Paris Auto Salon preview: Renault EOLAB

September 18, 2014 § Leave a comment

renault eolabRenault’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
