Renault ZOE e-sport conceptMarch 7, 2017
The Renault ZOE e-sport concept has twin electric motors providing four-wheel drive, almost 460bhp and torque of 640Nm, delivering a 0-62mph of 3.2 seconds.
Based on the all-electric ZOE’s supermini platform, the ZOE e-sport concept revealed at the Geneva Motor Show draws on Groupe Renault’s three years of success in the FIA Formula E Championship. This all-electric single-seater series, fought on challenging street circuits around the world, has proved a popular and accessible way for the public to enjoy high-performance electric racing.
The two-seater ZOE e-sport concept echoes the styling of the latest Renault single-seater race cars, and its colour scheme reflects the livery of the e.dams team. The lightweight body structure is made of carbon fibre, and the car tips the scales at just 1,400kg, including the battery (450kg). This minimal weight, in addition to excellent aerodynamics, power close to 460bhp and torque of 640Nm, helps the car to accelerate from standstill to 62mph in 3.2 seconds.
The ZOE e-sport concept’s stiff, lightweight structure allows for high performance, with superb grip and handling. Like the Renault e.dams Formula E single-seater, the bodywork is made from carbon fibre. The chassis features a tubular steel roll cage with protective Kevlar panels. It complies with FIA safety standards, allowing the ZOE e-sport concept to be used on race tracks.
Efficient aerodynamics are achieved with the aid of a front air dam, flat undercarriage, a Formula E-inspired diffuser and a large carbon fibre tailgate spoiler with a linear braking light.
Inside, the ZOE e-sport concept has two Recaro bucket seats equipped with competition harnesses and a driving position that is ideal for track driving. A rectangular steering wheel gives drivers the broader field of vision enjoyed by Renault’s Formula E drivers.
As in Formula E, the driver can adjust the powertrain settings and control energy consumption. The dash panel features three zones that permit management of the gearbox, driving mode (four options available) and brake distribution.
The ZOE e-sport concept’s powertrain is inspired by technologies developed by engineers at Renault Sport Racing and Renault e.dams.
Two motors deliver a total of 340kW – almost 460bhp. By comparison, rules laid down by motorsport’s governing body the FIA, limit Formula E single-seaters to 270bhp. The two motors are identical, with one at the front of the car, the other at the rear. And, as in Formula e, they feature high-capacity permanent magnet technology to maximise energy efficiency. To exploit all this power, the ZOE e-sport concept’s battery has a capacity of 40kWh.
As in Formula E, an air-and-water cooling system with a front-mounted radiator is used to make sure that the battery and control systems operate at the ideal temperature.
The ZOE e-sport concept also benefits from Renault’s Formula E experience in terms of optimised power delivery to the wheels. Renault-developed power electronics govern battery energy accurately and dynamically to meet the driver’s needs at any time. Energy management is completely configurable and adjustable after each drive or during race weekends.
The electronic settings offer four driving modes that adapt, depending on whether the driver wants performance or a longer range. They can also be tailored to suit different types of circuit and driving styles, adjusting the power delivery between the two motors to place greater emphasis on front- or rear-wheel drive.
Renault e.dams is the team with the highest number of titles in the FIA Formula E Championship, setting the standard in the discipline with two Team crowns, one Driver’s title, plus 10 race wins.
