Delta E-4 Coupe electric car hits 150 mph (240 km/h)
The Delta E-4 Coup? is an all-electric sport model with several direct-drive electric motors and a chassis made of carbon
The Delta E-4 Coupe made its track debut on May 9 at the Silverstone Circuit to test its ability to reach speeds of up to 150 mph (240 km/h).
The sport coupe is a creation of Delta Motorsport, a company founded in 2005 by Simon Dowson and Nick Carpenter and based right there at the Silverstone facility.
The two-door coupe is a lightweight electric sport model that features a carbon composite chassis that weighs just 85 kg (187 lbs) and is powered by several direct-drive electric motors with 120 hp (90 kW) and weighing just 23 kg (51 lbs) each, producing a total of more than 600 Nm (442 lb-ft) of torque.
The Delta E-4 Coupe has a range of up 200 miles (322 km), which is believable given that lightweight construction, and a 0 to 60 mph (96 km/h) sprint time of under 5 seconds.
Good stuff. Where could we buy this thing?
DELTA MOTORSPORT LAUNCHED 150MPH ELECTRIC CAR AT SILVERSTONE
Delta Motorsport, a highly innovative UK engineering consultancy based at the Silverstone Circuit, has designed and built the battery-electric Delta E-4 Coupé from the ground - up. Delta's focus on light weight and high-efficiency systems means that the stylish two-door coupe has a range of 200 miles on a single charge and yet can accelerate from zero to 60mph in less than five seconds.
May 9th saw the launch of the E-4 at Silverstone where it was designed and manufactured, attended by Quentin Wilson and Robert Llewellyn everyone got to drive and discover the next generation of electric vehicles using the very latest technological advances to achieve a greater driving performance.
The company, which was founded in 2005 by Simon Dowson and Nick Carpenter, has considerable experience in the motor sport and mainstream automotive sectors as well as other high performance engineering and clean technology projects.
Dowson says: "We became involved with the design of hybrid and electric vehicles because they share many of the engineering challenges associated with motor sport - light weight parts, aerodynamic efficiency and innovative packaging solutions. We've had to re-think road cars from the beginning, looking at low cost composite structures, system efficiencies and novel occupant packaging."
The key to the E-4 Coupé's impressive performance and range is the integration of all these technologies into a single vehicle:
- The carbon composite chassis, designed by Delta and manufactured by KS Composites, weighs just 85kg - 2/3 less than a comparable steel structure despite being designed to pass EU crash tests.
- The high performance direct-drive electric motors were designed in partnership with Oxford University and spin-out Oxford YASA Motors and produce well over 600Nm of torque and over 120hp each while only weighing 23kg.
- The low, sporty seating position with the batteries mounted under the floor means that the car handles superbly but it also helps reduce aerodynamic drag.
Development of the car was supported by a grant for research and development by the Regional Development Agency for the East Midlands area, EMDA. Five vehicles have been produced for the Technology Strategy Board Ultra Low Carbon Vehicle Demonstrator Program, the vehicles are part of the EEMS Accelerate consortium which aims to showcase high performance electric vehicles with cutting edge British design and engineering.
The Technology Strategy Board is a business-led government body which works to create economic growth by ensuring that the UK is a global leader in innovation. Sponsored by the Department for Business, Innovation and Skills (BIS), the Technology Strategy Board brings together business, research and the public sector, supporting and accelerating the development of innovative products and services to meet market needs, tackle major societal challenges and help build the future economy.
The Delta E-4 Coupe will be taking part in the RAC Future Car Challenge on Saturday 5th November 2011, one day before the London to Brighton Veteran Car Run, the world's longest-running motoring event. The event showcases the very latest low energy vehicles in a 60-mile trial from Brighton to London, with the challenge of using the least amount energy over the route.
