Renault’s EOLAB concept previews nearly 100 different technologies destined for production-fitment within the decade – including a hybrid powertrain. It also showcases Renault’s thinking for an affordable B-sector (supermini) car for “within 10 years”, i.e. a future-generation Clio, and has been developed with mass production in mind. It’s capable of 1 litre/100km (282mpg) fuel economy plus 22g/km CO2 emissions, aided by a 400kg weight reduction from the current Clio (to just 955kg) and a 30% reduction in aerodynamic drag. Features include a magnesium roof (just 4.5kg) and a steel, aluminium and composite bodyshell; the brakes are lighter and smaller, as is the centre-exit exhaust system, ‘tall and narrow’ tyres lessen rolling resistance, lighter window glass, thinner and lighter-weight seats, cabin fittings and trim, and variable ride height further aids aerodynamics.
Renault says that the hybrid powertrain will complement the EVs in its range, and that the EOLAB has an all-electric range of up to 60km at up to 120kph; the three-cylinder, 999cc (75bhp) SCe petrol engine works with a compact 40kW/200Nm axial flux motor, 400V 6.7kWhr lithium-ion battery and a clutchless three-speed transmission (first two gears for electric drive, the third engaged with the engine, giving a combination of nine gears in different modes). It foresees a ‘weekday’ (all-electric) mode for everyday commuting and errands, and ‘weekend’ combining petrol and electric power for longer-distance travel. No more details on charging as yet, but a key feature will include a driver interface specifically designed to engage drivers with their energy consumption and to encourage them to drive more efficiently. And the asymmetric 3-door layout with two rear-hinged doors on the right? To aid safety of passengers getting in on the kerbside, apparently (LHD).
- Another Paris preview: Peugeot Quartz, a crossover concept with plug-in hybrid drivetrain. This comprises the PSA 1.6-litre THP turbo engine (270bhp, 330Nm), six-speed auto transmission, an 85kW e-motor driving the front axle and a further 85kW motor to the rear; there are three driving modes, Road (engine plus front motor for maximum battery-charging during deceleration), Race (engine plus both motors), plus the all-electric mode with a range of up to 31 miles.
- Citroen, meanwhile, is to show a C4 Cactus concept called Airflow 2L – said to achieve fuel economy of over 2l/100km (141mpg). This prototype is 100kg lighter than the standard model, shows a 20% improvement in aerodynamics (thanks to side deflectors, active wheel shutters and auto-adjustable front bumper air intakes, modified wheel arches, spoilers and rear-view cameras in place of door mirrors), and has PSA’s Hybrid Air tech to reduce fuel consumption by 30%. Further details include lower rolling-resistance tyres, a smoother floor (featuring lighter-weight composite materials), carbon-based composite and aluminium structural elements and components, a polycarbonate sunroof, and LED light modules in place of the standard headlights. The drivetrain has the three-cylinder petrol engine plus two compressed-air energy storage tanks, which drive a hydraulic pump/motor unit to give an ‘air power’ zero-emissions mode in addition to air-assisted progress and petrol-only. It’s ‘medium-term’ with respect to the production-readiness of its technologies, apparently.
- A concept of a different kind: Stella, by students at TU Eindhoven, is a solar-powered four-seater capable of capturing more energy (to sell back to the grid) each year than it actually uses. An entrant in last year’s World Solar Challenge, it’s out and about in the SF area right now for the USA’s National Drive Electric Week, reports Autoweek.
- A lightweight micro-EV last seen at the Geneva Auto Salon, the Eon Weez, is ready for production, reports Automobile Challenges. Under the French quadricycle legislation, it can be driven licence-free. Interesting thing about it is its central driving position – like the McLaren F1, they report, though it’s rather more a la the ill-fated mia electric…

The Cité lib by Ha:Mo (harmonious mobility) project launches in Grenoble on 1st October, for a three-year trial; this puts 35 Toyota i-Road three-wheelers and 35 Toyota COMS micro-vehicles on the French city’s streets in a short-distance car-share programme. Partners include local authorities, EDF, SODETREL (an EDF subsidiary installing, managing and maintaining charging points) and the local car-share operator, Cité lib, with Toyota’s Ha:Mo management as trialled in Japan. It’s a one-way ‘free-floating’ system, with access to 27 charging stations where vehicles will be dropped off and plugged in, and the concept is to link people with local transport hubs for onward/inward journeys. “Urban mobility solutions will be a key growth for Toyota in the future”, says Takeshi Uchiyamada, Toyota Motor Corporation chairman. In the trial, data on technical issues and user behaviour will be collected.
- Here’s a nice thought to start the week: drivers are more motivated to employ eco-driving techniques by environmental concerns than by financial savings, according to a study reported here. Three groups of Dutch motorists (305 in total) were told six things they could do to save fuel/emissions; one group was told about the specific CO2 benefits, one about the financial, and the third given no info at all, and the lot told about the CO2 savings thought making the effort would be the most worthwhile. Even small ‘green’ gains were thought worthwhile, but small cost-savings not thought worth the effort.
- The first Motiv Power Systems electric garbage truck has gone into operation in Chicago, reports Clean Technica; this has a 9-tonne payload, is to work a 60-mile refuse and recycling round, and is the first of a fleet for the city.
- The problems of the Wankel rotary engine have been solved, apparently: Libralato Ltd‘s rotary – tested at Loughborough University – gets 40% efficiency, but is 50% smaller (and 30% cheaper to make) than a conventional ICE. It features a new thermodynamic cycle and engine mechanism, with a new switched reluctance motor (containing no rare earth magnets), and 48V operating electrics, and has been designed with a PHEV powertrain in mind. Libralato calls it the ‘Town & Country 48V Hybrid’ powertrain, or TC48, and says it would give (in an average car) a 15-mile all-electric range in town, and 54mpge (US) out of town. More here.
- New EV registrations in Q2 2014: 2746, a 141% rise on the same period last year. Calculations are that the total EV fleet of all ages in the UK (including PHEVs and vans) is now over 13,200 (thanks, NextGreenCar, who’ve added up the numbers). More here.
- Mercedes-Benz: sceptical of the concept of increasing urbanisation, planning for continued dwelling in the ‘burbs and indeed, a future of ‘mega-suburbs’, reports Fast Company.
- A smartphone app to simulate EV-driving: e.CODRIVER, developed at the University of Ghent, predicts the suitability of different EVs dependent on your driving needs and style (put phone on your dashboard). It can be downloaded free from Google Play.

And something backing up my suspicions that on-demand car-sharing (as distinct from fixed-location car clubs) may not be the urban transport panacea its advocates position it as being: a German study claiming that it created more traffic on urban streets in Berlin, was used in favour of public transport or cycling and mainly for short leisure journeys (an average 5.8km). Vehicles also spent nearly 23 hours a day parked and stationary, only a half-hour or so more than than average private car. There’s been criticism of the methodology (Car2Go claims its vehicles work 150 minutes a day) and of the study’s concentration on usage statistics without looking at behaviour change, however.
- Nissan, BMW, Volkswagen and Renault are co-ordinating in the EU-funded Trans-European Transport Network (TEN-T) programme to develop a multi-standard, interoperable network across the UK and Ireland, including over 70 rapid-chargers on major trunk routes; also involved in the project are Zero Carbon Futures (Sunderland) which will manage it, Irish energy co ESB, and Newcastle University, which will lead the research programme.
- Controlled Power Technologies (CPT) has been demonstrating its 48V hybrid tech at the Low Carbon Vehicle event at Millbrook this week: this is a proposal using low-cost ‘switched reluctance’ (SR) motor-generators, which are simple stepper motors in which a non-permanent magnetic field is induced. These are said to be very controllable, efficient across a wide speed range, and need no expensive permanent magnets or rare earth metals. CPT has also developed its latest LC Super Hybrid demo cars for advanced regenerative braking and advanced engine torque-assist from the SR motor-generator, and is seeing a 17% fuel economy improvement (to 57mpg) compared to the standard 1.4-litre Volkswagen Passat on which the demo car is based; CO2 emissions are down close to 115g/km but performance is said to emulate that of a 2.0-litre engine. CPT is also showing off the ADEPT concept developed in partnership with Ricardo (see below), as well as COBRA (Controlled Boosting for Rapid response Application), using the SR machines in electric superchargers for buses and commercial vehicles – a means of enabling engine downsizing and higher gear ratios as well as improving diesel emissions. This is being retro-fitted in a number of transport fleets.
- California-based Local Motion (San Mateo), vehicle-sharing tech provider to companies including Verizon, ride-share service Breeze, London’s EV-taxis Thriev, EDF and 1-800Courier (for Google Shopping Express deliveries) says it is scaling up deployment to nearly 90,000 vehicles; its fleet management/deployment/optimisation software includes keyless entry/access, enabling quick driver changeovers, and is said to facilitate fleet introduction of EVs. A name to remember…
- Another police alert: the Italian Carabinieri have taken delivery of 23 Mitsubishi i-MiEVs for use in city centres, on islands and in low-emissions zones, reports AutoblogGreen.

GM CEO Mary Barra has confirmed introduction of V2v-equipped models in two years’ time, and spoken at length about connected-car technologies at the ITS World Congress – full transcript of her speech here. To underline GM’s intentions, the latest prototype version of the EN-V 2.0 two-seater micro-EV (25mph top speed, 25-mile range) is on display – featuring autonomous-driving technologies, being fully fitted out with cameras, sensors and V2X communications including pedestrian-detection and sync-ing with traffic lights. Oh, and it’s gained a Chevrolet badge.
- Renault and Bolloré have announced their joint venture (30:70 respectively) for complete EV-sharing solutions (vehicle supply and operation) and development of a new Renault specifically for car-shares. Renault’s Dieppe factory is to start building Bollore’s Bluecar EVs from mid-2015. The existing Bollore car-share networks in Lyon and Bordeaux will gain Twizys on their fleets in addition to the Bluecar, with Renault vehicles to make up 30% of the vehicles offered ‘as quickly as possible’. The Renault under development – though still at a feasibility-survey stage – is to be a smaller, three-seat EV with Bollore’s 20kW lithium-polymer battery, smaller than the Bluecar; this could also be sold to municipalities, companies and consumers, says Renault, though its main raison d’etre is ‘to support the expansion of car-sharing initiatives’.
- Final conclusions from the 2011-2014 e-mobility NSR (North Sea Region) research programme have been published. Main pull-outs: Electrification a dynamic process – difficult to make long-term predictions. Realisation of public charging infrastructure a prerequisite – but must look at each scale, micro to macro, sort out interoperability. Need to combine actions of all actors, consumers, energy providers, distributors – overall system efficiency – but changing individual consumer/user behaviour also important. Lack of awareness/information gap biggest problem (info centres recommended, user simulation app). EVs good for urban freight, especially last-mile deliveries. Full report for download here…
- ‘Eco-routing’ navigation cut EV energy consumption by up to 51% in a trial and subsequent simulation by UC Riverside, though there were trade-offs for distance travelled, and, especially, journey time, which were in some cases not viable. The team thinks its system and algorithm for calculating optimal routing has potential for commercialisation. More here.
- GKN has three new technologies on display this week at the LowCVP event, Millbrook. First up, the battery-alternative Gyrodrive flywheel hybrid system for buses, said to give 20% fuel savings, be suitable for retro-fit and to last the lifespan of the bus itself; a new version of the GKN EVO e-drive system for passenger cars and delivery vehicles, integrating an axial flux motor with single-speed transmission and promising much higher torque and power density in a smaller, lighter package; and a downsized engine to act as a range-extender, incorporating the axial flux tech on its crankshaft in an integrated package. More here.
- Ricardo is demonstrating its ADEPT (Advanced Diesel Electric Powertrain) prototype at the LowCVP event. Fitted in a Ford Focus, this comprises the CPT ‘Tigers’ (turbine integrated exhaust gas recovery) plus Speedstart belt-integrated starter-generator and a lead-carbon battery pack, with 48-volt electrics. CO2 emissions are said to be under 70g/km, but the cost of the package considerably less than a full hybrid system. More here.
- The Mini ‘Superleggera’ electric roadster concept could be a goer for production, with a decision to be made early next year, reports Reuters.
- A stealthily quiet patrol car: Volkswagen has developed a police-specification e-Golf, with an 81-118-mile range sufficient for urban duties. It’s to go on display at a trade fair in Leipzig shortly, reports Autoweek.
- Electric vehicles could play a key role in a paradigm shift away from centralized electricity generation to solar microgrids, thinks Swiss bank UBS, which is advising its investors accordingly…
- How smartphones and apps are changing our ‘spatial thinking’ in terms of the way we relate to maps and journey-making: interesting piece at Citylab.
- “Electrifying America’s fleet of transit buses would put a far larger dent in carbon emissions than putting a few hundred thousand Teslas on the road”, argues Daniel Gross at Slate in a piece about bus-maker Proterra.
- Verizon has developed a provider-agnostic car-sharing app which integrates a number of its services. Verizon Auto Share features ‘scan & go’ QR code tech, with cloud data storage, and can be customised by service providers or clients. More here. And Valeo has partnered with French car-share tech firm VULOG to develop a Bluetooth-based smartphone access system for car-sharers, with the aim of creating a seamless and convenient user experience – more here.
- The EPSRC is putting up £6m-worth of funding for two low carbon vehicle projects: the ELEvate programme at Loughborough University to develop fuel cells and batteries for energy storage plus integration of grids, vehicles and devices, and the Ultra Efficient Engines and Fuels project at the University of Brighton, aiming for a one-third efficiency improvement from ICEs and near-zero emissions.

The latest iteration of Peugeot’s Exalt concept (last seen in Beijing in April) is going to the Paris Auto Salon next month. This big five-door saloon weighs just 1700kg and features a plug-in hybrid drivetrain delivering a total 340bhp from its 1.6-litre turbocharged petrol engine and 50kW electric motor, via a six-speed automatic gearbox and four-wheel-drive with regenerative brake energy recovery. Changes from the Beijing show car include a different ‘shark skin’ aerodynamic finish to the rear paintwork, and an interior trim made from recycled newspapers (in place of the earlier car’s ebony) – its pinkish tinge comes from certain business publications, apparently. In place of carbonfibre, there’s basalt fibre. And the finishing touch? A foldaway electric scooter (‘HYbrid-kick’) stowed under the boot floor as a last-mile solution.
- A blog from the New Cities Foundation explaining California’s PATH (Partners for Advanced Transportation Technology) research at UC Berkeley, and the ‘Connected Corridors’ programme: developing a framework to integrate traffic and incident management with personalized route guidance, in partnership with Caltrans and using V2V and vehicle-to-infrastructure (V2I, or V2X) communications. They argue that “transportation assets have been managed in silos” and that a holistic approach needs to be taken involving all transportation modes; while the focus is on reducing congestion and improving safety, while moving people – an goods – in as efficient a way as possible, reducing vehicle emissions is also a consideration.
- “The most important transportation innovation of this decade is the smartphone“, argues Eric Goldwyn (Columbia University) at Citylab – also making the case for public authorities to take control of app provision and multimodal integration, rather than leaving it to start-ups and to independent corporations such as the Googles of this world. Goldwyn looks at regulation and public policy, with reference to the ongoing Uber controversy, and cites Prof Elliot Sclar (Columbia) in calling this a missed opportunity for cities, which should be taking leadership, especially as more and more privately-operated transport options come into the frame.
- On a different (though not entirely unrelated) note, a big report from UCL on transport and poverty: the authors discuss spatial mismatch (the dynamics between housing, jobs and transport networks, i.e. more affordable housing being in areas with poor or expensive transport connections), transport-related social exclusion and social justice, to examine issues such as the dynamics between poverty, transport behaviour and mobility, car-dependency (with particular focus on low-income groups in rural areas), risks of death on the roads and exposure to air pollution, and the impact of schemes to improve access to transport and mobility for key services, education, finding work and soforth. Lots of useful references and data.
- So transportation design students at Art Center College of Design, Pasadena (training ground for many of the world’s best-known car designers) are being asked to take a different approach, reports The Guardian: rather than drawing stand-alone cars-as-products, they’re being told to look into the whole automobility system (as students have long been doing at the RCA in London), and address issues such as parking and the idea that vehicles spend 90% of their time idle, the land use that this entails, and the inherent all-round inefficiency of the private car. (This is in California, note).

Picture: Mitsubishi Outlander PHEV Concept-S, a sported-up version of the Outlander plug-in hybrid (one of Europe’s most popular plug-in electrified vehicles), to make its debut at the Paris Auto Show next month.
Some reading for the day: Latest report from ITS America (Intelligent Transport Systems) estimates the fuel and oil savings which could be delivered by the introduction of various technologies, including intelligent cruise control, traffic signal coordination, smart parking info, GPS tracking and wireless monitoring of fleet vehicles, optimised navigation and vehicle platooning. It also claims that plug-in hybrid and electric vehicles could bring fuel savings of 409.8million and 361.5million gallons per year respectively, though with current sales trends, petrol-electric hybrids “represent the most significant fuel savings” over the next ten years. Full report, focusing on four case studies, here.
- Interesting article at CityLab on the carmakers’ attempts to woo Millennials – yep, apps, tech, smart accessories, etc. But not a note on the other reasons this age-group aren’t driving (in the US, at least) – increasing urban-dwelling, their financial insecurity; it’s surely not all about them being more into their iPhones than cars? Point made about grabbing their interest now with a view to capturing them in 15 years’ time when they do come into the car market, though (as if this is a good thing. Opinions – from sustainable transport world, the automakers – may differ, obviously).
- Mini-media round-up: today, the Telegraph’s motoring team’s come out broadly in favour of ‘shared space’ road zones in city centres (something I’ve written about in the past…), following the well-argued ‘motorists have ruined England’ piece and advice to get kids cycling to school… Is this some kind of an indicator? (Probably not: but some evidence of a broadening of debate on transport matters in the conservative press?). Meanwhile, the Morning Star’s calling for re-nationalization of bus services, pointing out that inequalities in mobility exacerbate inequalities in services, access to jobs and soforth in remote rural areas (this is an issue in deprived urban districts, too, of course).
- South Korea has delayed a vehicle ‘smog tax’ in response to pressure from its domestic car-makers. Lobbyists claimed that the tax would cut Hyundai’s sales by 10%, according to this report.
- UK car sales: 72,163 in August, 9.4% up on August 2013, the 30th successive month of growth, over 1.5million new cars sold so far this year… The greater surge has been in private registrations – a rise in consumer confidence, says the SMMT – but fleet is also up. Alt-fuel vehicles (including EVs and hybrids but also LPG/CNG) have accounted for 27,887 sales year-to-date (up 48.7% on this time last year).
- Renault-Nissan is supplying 200 more EVs to Orange in France, mostly to be shared by employees and booked via Orange’s Auto Partage app. The fleet – Zoe superminis, Kangoo ZE vans, the Nissans e-NV200 and Leaf – will join the 30-odd Renault Twizys Orange is already running.
- Tech problems are the most common issues reported with new cars, according to a survey by JD Power, with voice-recognition and Bluetooth connectivity the glitchiest. The survey warns that consumers, though interested in such systems, are frustrated when they don’t work, and are unwilling to pay much more them. More here.
- However… Daimler has snapped up a couple of transport apps, mytaxi and RideScout, to add to its Moovel transport services unit (which also includes Car2Go and Park2Gether). It had owned a share in mytaxi – an Uber rival but for the booking of licensed taxis – since 2012; RideScout, functioning now in 69 North American cities, gives info for a range of transport options including car-sharing (Bloomberg, via Detroit News).
- EVs: a likely market is as second or third cars for wealthy families, says Jaguar-Land Rover head of product development Wolfgang Ziebart. “We see some Range Rover owners or owners of high-end Jaguars as potentially being attracted to electric vehicles”, he notes, suggesting a two-part market with the other sector being EVs as inner-city transportation, in which JLR is less interested. Other JLR plans: increasing the all-electric range and capabilities of its hybrids (Automotive News Europe).
- Propane: can be synthesized for transport fuel from e-coli bacteria, according to a team from University of Turku, UCL and Imperial College, London. Though it is a long way from commercial production, the metabolic pathway identified also has potential to incorporate ‘solar-powered’ cyanobacteria. More, incl. academic citations, here.

An interesting research paper from Lisbon in this journal (open access): 25 EV drivers (private and fleet) tracked for a year, giving feedback through interviews and online diaries. Environmental and economic factors were the primary motivators for the private drivers to go electric, while the fleet drivers cited their company’s image. Over the year, a well-to-wheel analysis showed an estimated 35-43% reduction in energy consumption by the drivers, and a 58-63% fall in CO2 emissions. Full paper here. (OK, I know this picture doesn’t show Lisbon. Generic EV-charging pic, taken in my ‘hood).
- Latest e-motorbike and e-scooter forecast from Navigant Research: 55 million to be sold worldwide from now ’til 2023. Though China is the primary market for electric two-wheelers right now, from 2015 growth is expected in other regions; the report also identifies successful niches in the fleet market such as law enforcement and small cargo delivery.
- An important step in solving home-charging access for EV drivers: in California, a bill has been passed giving rental tenants the right to install charging equipment (as long as they pay for it themselves, have suitable insurance, and gain their landlord’s approval), reports Charged EVs. The state has also just approved $1million of funding to support infrastructure, including fast-charger installation, in Encinitas and Sonoma County; more here. And China’s planning to plough $16billion into developing charging infrastructure, reports Bloomberg. Oh, and Rotterdam: a 2,500 euro scrappage grant to crush dirty older vehicles – in addition to the nationwide Dutch scheme giving 3,000 euros towards purchase of an EV, plus further local incentives (a slightly different scheme in Amsterdam, for example) of up to 7,000 euros. More here.
- LG Innotek has developed a motor for DCTs which is rare earth-free: the motor enables fast and smooth switching between gears, and is said to give a 4% reduction over a conventional DCT (dual clutch transmission). Press release posted here.
- Experiments in nanotech at MIT into a thermopower wave process suggest that electrical pulses of energy could be generated from burning liquid fuel, in an energy-dense and low-emissions process. Some details at Transport Evolved.
