Beijing-based ‘clean energy’ company Hanergy has unveiled four solar-powered EV concepts, each featuring its thin-film, lightweight PV tech applied over roof and bonnet. The four, revealed at an event in Beijing, are said to “acquire power directly from the sun” and “do not depend on charging posts”: they’re said to generate 8-10kWhrs of power a day (based on 5-6 hours of sunlight) giving a range of about 80km, though they can be externally topped up as well.
The rather unique-looking vehicles [sorry, can’t find official-issue pics of these individually] are Hanergy Solar R (a sporty RWD two-door, with extra solar cells in its door panels); Hanergy Solar O (a city car, said to come with two rechargeable e-scooters in its boot); Hanergy Solar L (a gullwing-doored MPV said to weigh just 700kg); and Hanergy Solar A (an angular two-door with extra fold-out panels). Optimistic as these concepts may sound, there’s certainly some viable tech here which could prove useful for range-supplementation, if not to completely power a long journey in the near future. Report and snaps from the event, showing the cars more clearly, at China Car News.
- Much indignation in the UK EV world this week as Ecotricity announced its introduction of a £5-per-20min* fee for use of its Electric Highway rapid-chargers. Free for Ecotricity home energy customers, though… My thoughts: it is entirely unrealistic to expect ongoing free use of facilities which have been expensive to install and maintain, as well as free electricity for one’s motoring. However, the cost-per-mile analysis now puts use of these chargers in an unfavourable position re. diesel, and makes it unfeasibly expensive for PHEV drivers to have a quick zap-up (so they’ll be on the motorways using their ICE instead). Most worryingly for me, though, is that access to the chargers will now be only via smartphone app (iPhone, Android) rather than via RFID tag or on-the-spot credit card payments, which is going to cut down on accessibility and rule out usage by EV drivers who don’t wish to have a smartphone (and such people do exist – I’ve interviewed them). Predictably, operators of other networks and PAYG systems are meanwhile rubbing their hands and also keeping a very close eye as to how this pans out. One positive thing for all-EV drivers, though, is the lessening likelihood that they will be ‘Outlandered’, of course. *Subsequently amended – £6 per 30min the deal now, it seems.
- The folks at Zap-Map have now added the new Tesla Destination Chargers (slower than Superchargers) to their increasingly comprehensive charging map database; also, for FCEV drivers, hydrogen pumps (only 15 of those so far in the UK, though).
- BMW showed a grid-connected static home energy storage system – using second-life i3 batteries – at the EVS29 event in Montreal; more here. No word on when such a product will be ready to market.
- Nice feedback from the BlueIndy EV-sharing scheme in Indianapolis after nine months: 2, 100 registered members, 21,500 separate trips made, 230 cars and 74 operational sites (another 25 under construction), 70% of owners with annual membership and the rest less frequent users – going to and from the airport is a popular journey. Interesting thing is that users (average age 42) fall into three groups, with one portion being ‘service workers’ – low-paid people using the cars to access employment opportunities, which suggests a growing role for car-share in increasing mobility options for marginalised/low-income groups. Other users tend to be couples substituting for a second car, and occasional management-level businesspeople, apparently, and the scheme is now aiming to target students.
- On that note, BMW/Sixt’s DriveNow on-demand car-share has now opened in Brussels, its 10th European city (it’s also in Berlin, Hamburg, Munich, Dusseldorf, Cologne, Vienna, Copenhagen, Stockholm and, if we can still call ourselves European, London). Latest stats from the scheme include: over half a million journeys in Germany each month; average journeys between 8-15km and 20-40 minutes; over 600,000 customers. 20% of the fleet is now electrified.
- Report for the LowCVP and IMechE from the Institute of Transport Studies (ITS), University of Leeds, calls for strategic policy interventions – needed if potential for cleaner, cheaper, lower-energy car travel is to be achieved through combination of connectivity, [less importantly] automation, and vehicle-sharing. ITS reckons that vehicle-infrastructure comms can improve energy efficiency as well as improving journey times and road safety; impact will depend on further innovation in system design; full automation could help reduce practical difficulties of recharging/refuelling, and that much work needs to be done on increasing car-shares. It warns that autonomous vehicles may, however, lead to increased traffic and energy demand. Full report – Automated vehicles: Automatically low-carbon? – available here.

Lots of column inches last week devoted to the Rolls-Royce Next 100 and Mini Next 100 concepts – interesting vehicles, of course – but this prototype took my fancy too. Olli is a 3D-printed autonomous-driving 12-seater shuttle bus, built by Local Motors, showcasing the IBM Watson IoT cloud-based cognitive computing/vehicle connectivity platform (including speech commands, speech-to-text communication, and 30 embedded sensors). Its design, developed in a crowdsourcing process, is by Edgar Sarmiento from Bogota, who will receive royalties as/when the vehicles go into production. Testing is to start in Washington DC with further trials to follow in Miami-Dade and Las Vegas; more Ollies are being made at the LM HQ in Phoenix. Olli is conceived as part of an ‘ecosystem’ including consumer smartphone apps, and can be shared, chartered and otherwise summoned as well as operating on pre-determined routes; it’s proposed for campus-type environment or developments but also to fill in the gaps in a city’s established transit infrastructure.
Anyway, the BMW group reveals: the Mini Vision Next 100 is a nice little thing, showing some more of the BMW Group thinking: it’s designed to be an on-demand, shared-service EV, which will adapt to the driver’s tastes and preferences, provide a kind of concierge service, bring itself to the user (or take itself off to park), and remain fun to drive. Full details on its design here, but further notes on it are that it has a high recycled-material content inside, including cellulose-derived trim. The Rolls-Royce Vision Next 100 is more of a flight of fantasy, a fully-autonomous (without even a steering wheel) proposal for the future ultimate luxury car, again electric-drive, with a virtual assistant.
Both cars – and the BMW Vision Next 100 (see previous post) – are the expression of BMW’s “six central hypotheses for individual mobility in the coming decades, based on key megatrends and future projections.” These six are: Mobility is becoming versatile (new forms and modes of mobility); Connectivity is becoming second nature; Mobility is becoming tailor-made; Technology is becoming human (including adaptivity, learning); Energy is becoming emission-free; Responsibility is becoming diverse (the CSR bit).
- The Hubject project (integrating charging infrastructures across Europe in a single platform) is collaborating with mapping providers HERE to provide real-time information on charging point status – fully-automated updates across the network on occupancy, availability etc. More here.
- Nissan is researching a solid oxide fuel cell (SOFC) powered by bioethanol, natural gas or multiple fuels: in this first automotive application of SOFC tech, the fuel reacts with oxygen in a reformer to create hydrogen, which then reacts in the fuel cell stack to produce electricity as per a conventional hydrogen fuel cell. The e-Bio Fuel Cell is said to give cruising ranges similar to those of petrol-powered cars alongside the driving experience of an EV. Sounds complex, and of course, there’s the issue of the source of the ‘bio’ ethanol, but Nissan’s pointing to region-specific applications where this can provide cleaner transportation within an existing fuel supply infrastructure, and an “ample power supply” to suit a wide range of needs, such as refrigerated deliveries. Some commenters are also suggesting that this could negate the need for hydrogen production/supply for fuel cell vehicles.
- Latest Navigant Research report on urban transport: car-sharing, with a growing proportion of EVs on fleets, is a growth trend, boosted by an increase in one-way on-demand services and underpinned by network connectivity. It expects almost all major manufacturers to be offering some kind of shared service by 2025, and customers are expected to use on-demand vehicles alongside ride-hailing services such as Uber. The shared fleets are also the key arenas for introducing autonomous-driving elements [i.e. for getting a car to come to you, or for parking itself when you’ve finished]. This is a familiar – and rather idealised – picture now, but more detail in this handy digest by Forbes.

Quick rundown of – my pick of – Tokyo motor show debutantes and show stars: first up, Nissan IDS, previewing the next-gen Leaf as well as Nissan’s upcoming autonomous tech (production, 2020). It features manual drive and a ‘learning’ automated Pilot Drive mode, said to mimic the driver’s own style and preferences; in this, the steering wheel retracts into the IP, and all four seats rotate inwards a little, under atmospherically dimmed lights. More clues to the next Leaf – or a new member of the Leaf family – include optimised aerodynamics, lower height, wheels pushed out further to each corner, super-thin tyres, and wheels with a fin-type design to smooth air flow. Oh, and a 60kW battery, wireless induction charging, reduced weight (thanks to a carbonfibre body) and the promise of “long distances” between charges. Automatic parking, too. More here. (And the dead cute Teatro for Dayz is – theoretically – electric and autonomous, too).
Latest news from Gordon Murray Design with its iStream Carbon chassis tech in the Yamaha Sports Ride Concept sports car; the structure is said to be affordable, suitable for high-volume production, and thus brings F1 lightweighting to everyday vehicles via the GMD iStream production process. The Lexus LF-FC previews the next-gen LS and features a fuel cell powertrain; Honda’s fuel cell rival for the Toyota Mirai is called Clarity and it’s coming to the UK; on a more conceptual note, the Mercedes-Benz Vision Tokyo (an autonomous minivan-like mobile lounge for young people in future megacities…) also features an ‘electric hybrid’ fuel cell powertrain with induction charging and total 980km range. And the all-electric Mitsubishi eX compact crossover concept has been well-received, too.
Away from Tokyo… Another autonomous electric bus has been launched this week: the Navya Arma, which can carry up to 15 people at up to 45kmph (on private sites, at the moment, its French makers suggesting industrial sites, airports, amusement parks, hospitals and tourist resorts as potential applications as well as urban areas). It can be induction-charged, and is now in production; three were seen in action at the ITS World Congress in Bordeaux, shuttling 1500 people on 2km trips between centres.
- Two US surveys: the Electric Vehicle Information Exchange questioned 990 EV owners and enthusiasts, and concluded that they were primarily “very well educated, upper-middle class white men in their early 50s with ideal living situations for EV charging”, reports USA Today. Almost all owners had their EV as their primary vehicle, but interestingly, “energy independence, and not environmental anxiety, was the primary reason that these respondents became interested in electric vehicles”. JD Power, meanwhile, has declared that EV prices must come down, and that public infrastructure must improve, if sales are to grow beyond a small proportion; this is despite large savings on fuel bills found in a survey of 7,600 owners who saved an average $147 a month on gasoline but saw their utility bills rise by only $18. One in three owners took advantage of discounted off-peak electricity tariffs; 43% charged their vehicle away from home, and when they do, 85% charge somewhere free. Average daily commute is 34 miles, and only 11% suffer range anxiety, apparently.
- And also across the Atlantic: Montreal is aiming for 1000 EV charging points by 2020, with the first 100+ in by next spring. Worth noting that this is in combination with Quebec’s plentiful hydro-electricity. Another snippet (via electrive-com): 50 Renault-Samsung SM3 saloons are going into a trial EV-share in Seoul; plus a fleet of 30 Toyota COMS micro-vehicles are going into an on-demand fleet on the island of Okinawa.
- Am liking the sound of the Power Road: not just incorporating solar panels and wind turbines on bridges and other structures, but generating more energy over its lifespan than it cost to make. This SINTEF project in Norway is looking at electricity-generating materials for EV charging, as well as locally-sourced, low-energy materials for construction.

We’ve seen this before in Munich, but the Light & Charge low-energy LED streetlight/EV-charger has been installed in the UK for the first time – at Mini Plant Oxford. It proposes an integrated solution for local authorities whereby street lights can be replaced with one of these without adding to urban clutter. Up to four LED modules can be fitted on each post, which has a modular design; these can be self-adjusting and reduce their output at timed intervals or when no-one is around, and light can be targeted and diffused to minimise glare or light pollution. From the EV-charging point of view, it’s been designed to be vehicle-agnostic and to be activated via swipe-card.
- Daimler/Car2Go is working with Bosch on a smartphone-app controlled automated parking system, hich will be tested in a parking garage; this is seen as an important step towards fully-automated driving as well as added functionality in the car-sharing business model. More here. And Jaguar Land Rover has today shown off a remote-controlled Range Rover Sport, driven by smartphone – not just for parking, but for negotiating tricky off-road conditions from a safe distance (within 10m), perhaps. This car is capable of doing a full 18-degree change of direction so even three-point-turns itself. The tech takes control of steering, braking, acceleration and gear selection, and JLR’s referring to the “Solo Car”. Also from JLR recently: the ‘Pothole Alert’ tech – identifying location and severity of potholes and adjusting suspension accordingly – isn’t just a shock absorber-saver. Interesting thing about this is that this is data to be shared with other cars and with road authorities, and is thus a step towards cloud-enabled internet-of-things-sort-of-things, as well as autonomous driving.
- On a related note – insights from McKinsey give 10 ways autonomous vehicles could change the automotive industry. Full read here, but they’re looking at three distinct eras. In the present, they’re already making inroads in industrial applications; new mobility models are emerging; and carmakers are assessing the market. As consumers start to adopt them, changes appear in the aftersales sector; supply chains and logistics are redefined; and the insurance market starts to cover tech failures rather than individuals. Once they predominate, they could free people up for 50min a day; parking space is reduced by billions of sq/m; crashes – and related costs to society – are reduced by 90%; and they accelerate robot tech in general.
- 1.3million Americans had joined a car-share by the end of 2014, according to the latest data out of Berkeley; this report from the Freep looks at that, noting that Airbnb-style peer-to-peer car-sharing is also a growth area – but that actual car sales are also growing again too, including to millennials/Gen Y. Another interesting point is illustrated by data from Zipcar – whose members include a sizable proportion of 50-69 year-olds – which suggests that older Gen X/boomers are moving back to city centres and getting rid of private vehicles. Which turns around a few ideas that have been floating about in recent years. More on vehicle-sharing from the TSRC, UC Berkeley, here.
- The Bollore Bluecar EV (previously built in Italy) is to be built at Renault’s factory in Dieppe, with a co-operation agreement signed between the two industrial groups. The Bluecar is, of course, headed to London for the EV-share (finally) announced last week. Where it will be painted red, incidentally. A 50-car fleet is to be launched early next year, with a (much-needed) overhaul and expansion of the city’s malfunctioning charging infrastructure also promised.
- Next year, Scania is to start testing hybrid diesel-electric heavy-duty trucks charged via an overhead pantograph system; a 2km test stretch of road is being built as part of the Electric Roads initiative. Later in the year, a similarly-equipped bus will also begin trials; this can be fully recharged in 6/7 minutes from equipment at a bus stop. More here.
- More bus news: Route 55 in Gothenburg has electrified with three all-electric and seven hybrid buses from Volvo (obviously) up and running; there’s flash-charging at bus stops, using renewable wind/solar electricity.
- And VDL Bus & Coach (Netherlands) has unveiled its articulated Citea SLFA Electric, due to go on duty shortly in Cologne; again, this has capability for ‘opportunity charging’.
- New BMW 7-Series: plug-in hybrid variant, 740eLe (long-wheelbase only), does up to 40km in all-electric mode (up to 75mph) and its averaged-out figures (meaningless though they are) are 134.5mpg and 49g/km of CO2. xDrive AWD versions also available.
- EU first-quarter figures for alt-fuel vehicles include a rise in all-electric sales, which more than doubled to 24,630 Jan-March 2015.
- Tesla: not as disruptive as you might think, according to Harvard Business School Professor Clayton Christensen, who points to ‘neighbourhood’ EVs – micro-vehicles – as the real innovations with potential for disruption. Mmm. Anyway, comes off the back of Newsweek’s ‘green’ rankings which puts Tesla as only the eighth-placed carmaker, behind BMW, Toyota, Daimler, Nissan, Ford, Volkswagen and GM in an analysis taking into account factors including energy and water use in manufacturing. Not that I imagine Elon Musk is losing any sleep over either of these judgements.
- Commuters want seamless connectivity on their journeys, according to a report from the Ericsson Consumer Lab, and to be able to take charge of their travel decisions with real-time info and personalised services. Some useful stats on use of apps by people taking different transport modes, in the various cities studied (London, Sao Paulo, New York and Shanghai). Also, feedback on rapidly-developing consumer trends in app use and expectations of iOT/connectivity in this video.

A very quick Shanghai Motor Show round-up of stuff not previously covered/mentioned, in no particular order. Volkswagen: followed up the Geneva Sport Concept GTE with the C Concept GTE – stretched to a 5m-long four-door luxury “coupe” bodystyle, with a 245hp plug-in hybrid powertrain (four-cylinder TSI engine, eight-speed auto gearbox, 124hp electric motor). This can do up to 81mph in all-electric mode, with an all-electric range of up to 31 miles/50km; averaged-out economy is 122.8mpg and CO2 emissions 55g/km. Another plug-in hybrid: Qoros 2 SUV PHEV, a chunky little concept with hands-free and optional inductive wireless charging; and the latest in Audi’s Prologue series, the plug-in Prologue Allroad (previewing the next A6 Allroad) with 4.0 twin-turbo plus electric motor giving 724bhp. Toyota unveiled a series of Chinese-market hybrids and EVs; Cadillac supplemented its CT6 saloon with PHEV capability; BMW launched the X5 xDrive40e PHEV; the Chinese will be offered a hybrid Nissan Murano, and a plug-in hybrid Audi A6 L e-tron and Q7 e-tron 2.0 TFSI quattro. One of the more interesting and forward-looking concepts, however, was the Chevrolet FNR (“find new roads”, pictured) from GM’s Pan Asia Technical Automotive Center in partnership with SAIC Motor, which featured in-wheel electric motors, wireless charging, autonomous-driving capability with sensors and roof-mounted radar, and an interior which enables 180-degree swivelling of the front seats when in self-driving mode.
- A step forward in synthetic fuels: an Audi test facility in Dresden has produced its first batch of ‘e-diesel’, synthesised from carbon dioxide from a biogas plant. The process needs only ambient air, and works in stages: water is heated for steam, which is broken down into hydrogen and oxygen by electrolysis (using renewable energy); the hydrogen then reacts with the CO2 to produce ‘blue crude’, a long-chain hydrocarbon compound, which is then refined. This end-product is said to be free of sulphur or aromatic hydrocarbons, with a high cetane number,and it can be mixed with conventional diesel as well as used ‘pure’. The overall high-temperature process is claimed to be 70% efficient, with the added bonus that it can be incorporated into electricity grid stabilisation. Audi is aiming to produce over 3000 litres in coming months and then scale up the principle; petrol made in a similar way is also under development. More here. A classier news-release approach than Toyota’s talk about ‘hydrogen bullshit’, perhaps (hydrogen from cattle manure).
- Audi has also delivered 40 A3 e-tron PHEVs for testing in three trial programmes in Berlin, Munich and Stuttgart: these are to look at private consumer use, expectations and charging. More here.
- Montreal is to get a municipal EV-sharing scheme: 250 cars to hit the streets by next spring, with the aim of 1000 by 2020. Importantly, this will be powered by Quebec’s abundant hydro-electricity. More at Treehugger.
- Barriers to EV adoption: vehicle cost, current battery tech, lack of consumer knowledge, reports the US National Research Council. Findings summarised here.
- Siemens has launched a cloud-based wi-fi enabled EV charging station that enables vehicle owners to activate and control/monitor vehicle charging remotely via mobile or web app, integrating into demand-management and grid-balancing incentives. More here.
- Millennials: buying cars again, and more than GenX, though mileage and driving rates are down across the board and there’s much variation between cities/location. Summary here.

Its retro design might not be for everyone, but the Dutch-made Meijs Motorman electric scooter is, according to Wired, “taking over Europe”. No bad thing, the use of clean two-wheeled commuting solutions, and stylish, design-led products in the marketplace can only help raise the profile of e-scooters, mopeds and electromobility in general. Prices start from 4,750 euros (excl. VAT), with customisation options available from this Maastricht-based bike-builder. Rather nice-looking, in my opinion, but then I do like a bit of stripped-down vintage-look styling with the benefit of modern technology, modern maintenance demands and modern-day attention to air quality.
- BMW’s confirmed UK sales in the autumn for the X5 xDrive40e, a plug-hybrid (why am I less excited about this than the above e-scooter?). Its total output is 313hp (245hp from its four-cyl 2.0-litre petrol engine, 113hp from its e-motor), with combined CO2 emissions of 77g/km and fuel economy up to 85.6mpg; it’ll still do 0-62 in 6.8 seconds and 130mph (up to 75mpg in all-electric mode). All-electric range, varies – “short, everyday journeys in urban areas can easily be completed with zero tailpipe emissions”, says BMW, promising an equivalent 94.2mpg for 15 mile-odd trips in city traffic or a return of 43.5mpg over a commute of up to 37 miles. In the optimised MAX eDrive mode, 19 all-electric miles are possible. However, long-distance (and higher-speed), fuel consumption is “above 25.7mpg”, more in line with a conventional SUV of this size. There’s eight-speed Steptronic transmission and permanent all-wheel drive, too, and a battery-save mode enabling a build-up of charge (giving range) for later deployment, i.e. when entering a zero-emissions city centre zone (when such things arrive and are enforced). Owners are further offered the BMW 360° ELECTRIC service, with a choice of Wallbox home chargers, membership of the ChargeNow scheme, ParkNow Longterm parking/charging space-booking and further customer services. More details here.
- Ford’s car-sharing trial in London is going well, reports CleanTechnica, with users of the 17p-a-minute City Driving On-Demand service initially opting for the ICE Fiestas, but switching to the Focus Electrics when they are familiar with the app-driven booking process – and not going back.
- Research at Imperial College, London, has untangled (some of) the chain of cause-effect linking diesel particulates and respiratory distress – the diesel particles are found to activate sensory nerves in the airways. More here.
- And a new study from NYU (outlined here) linking fine particulate matter (PM2.5) with artery-narrowing and strokes: PM2.5s mostly come from diesel exhaust (as well as from non-transport sources such as wood-burning stoves) but gasoline direct-injection engines are increasingly the culprits as well (more on that here). T&E reports that EU-wide, vehicle traffic contributes a fifth of PM2.5s to the atmosphere.
- Congestion on UK roads is the worst it has been for over 10 years, according to a survey by the Freight Transport Association (and they should know…). The FTA is noting an increase in domestic road freight but a 55% rate of decline in reliability on the motorway network; also, an expectation of “robust growth in domestic road freight activity” in most industry sectors and regions in the first quarter of this year. Its proposed solution is more investment in the road network, however, rather than, um, fewer vehicles (of all types?) and smarter use of the roads we have. Reminder, too, that transport issues ain’t just about cars.

Mitsubishi has released more details of its small SUV concept, a plug-in hybrid, prior to next week’s Geneva Auto Salon. The XR-PHEV II has a new powertrain promising a motor output of 163hp (no details yet on the engine) and overall emissions below 40gkm, and is front-wheel-drive despite its mini-Shogun styling; think next-generation ASX urban crossover. It has all-electric, series hybrid and parallel hybrid modes – designed for prioritising all-electric operation, with the engine acting as a generator, but the engine can also kick in to supplement the motor power.
- Toyota is putting its i-Road into action in an EV-share in central Tokyo next month, in partnership with Park24’s Times Car Plus service. A trial – supplementing Toyota’s programme in Grenoble, France – will run till the end of September to gauge user feedback, activity patterns and ease of usage.Toyota expects the cars, to be located at the Times Station, Yurakucho ITOCiA shopping centre, to be used one-way to businesses, shops and sight-seeing locations; they can be returned to any of five central bases. Times Car Plus members opting into the service will pay 412 yen (about £2.25) per 15 minutes with max hire time two and a half hours. There are around 430,000 members of this mobility service (operated by car park network Park24) across Japan.
- Springer has published a book on Electric Vehicle Business Models, including case studies and research on car-sharing, wireless charging, grid-balancing, marketing (‘technology push vs market pull’), and cost of ownership; more details and samples here.
- Volkswagen’s Geneva concept previewing the next CC is to have a (petrol) plug-in hybrid powertrain, reports Autocar, but the Audi Prologue Avant (next-gen A6 Avant estate) is diesel-electric – 3.0 TDI engine, 353hp, plus 100kW motor and eight-speed tiptronic transmission, delivering 0-62 in 5.1 seconds, 155mph, 176mpg overall, 43g/km and a 54km range in all-electric mode. Wireless induction charging capability, too.
- Zap-Map.com has launched a mobile app (£4.99, iOS, Android to follow) enabling UK EV drivers to search for public charging points (by rated power, connector type or compatibility with their vehicle as well as by postcode or location), and to provide feedback and ratings , i.e. on correct functioning. It’s the first of a series of apps the Zap-Map/Next Green Car team (managers of the government-funded National Chargepoint Registry) are developing to support electric car drivers. More here. This follows debate on EV user forums about the ins and outs of repurposing and selling data from OpenChargeMap and other OS databases…
- Some notes from a DEMAND Centre workshop on energy demand in relation to time use and social practices, including with relation to mobility and car-dependency; research presentations looked at factors including sequence patterns of activities and energy/mobility-intensive activities and practices.
- Proterra has upgraded its e-bus battery packs to deliver a range of 180 miles; more at Green Car Congress.
- Not all biofuel bad: the Greater London Authority is planning to get vehicles used on council fleets running on a blend with used cooking oils, fats and greases, and Hackney is to trial blends of B20 and B30 in its LCVs by the end of the year, reports Fleet News. This could also help tackle the problem of ‘fatbergs’ clogging the capital’s sewers.
