One of the real live wires at the 2010 Paris Motor Show will undoubtedly be the Audi e-tron Spyder, a two-seat open sports car study with plug-in hybrid drive capable of delivering 128mpg economy and 59g/km emissions from its 300PS twin-turbo V6 TDI engine and twin electric motors.
The Audi e-tron Spyder's low total weight of only around 1,450 kilograms, combined with the high-torque TDI and the two electric motors results in impressive performance. The car accelerates to 62mph in just 4.4 seconds, and top speed is electronically governed at 155mph.
The Audi e-tron Spyder can combine the powerful 650Nm torque output of its TDI engine with the 352 Nm developed by its two electric motors during acceleration in a process known as "boosting."
The intelligent distribution of power allows for optimal dynamics in every situation. The targeted application of power to the front wheels improves longitudinal dynamics while also improving lateral dynamics when cornering. This is because torque vectoring - the 'on demand' distribution of torque between the left and right wheels of the two axles - enables an exhilarating degree of driving precision and excellent agility.
Thanks also to its low weight, short wheelbase and perfect 50:50 weight distribution for dynamic handling, the Audi e-tron Spyder has all the drivability of a go-kart - good on bends and neutral right up to the very high handling limit.
The combination of a highly efficient TDI and electric drive also provides for excellent fuel economy and amazingly low emissions. The Audi e-tron Spyder can cover up to 128.4mpg, corresponding to CO2 emissions of 59 g/km. A range of more than 621 miles is possible with the 50-litre tank.
The open sports car can also drive strictly on electric power and thus with zero emissions over distances of up to 31.07 miles and at speeds of up to 37.28mph - an obvious benefit in urban areas.Published 1 October 2010
