Audi has unveiled a new e-tron concept at the Paris Motor Show called the Audi e-tron Spyder. The concept utilizes two electric motors producing 88 hp and 259 lb-ft at the front axle and a twin-turbocharged 300-hp 479-lb-ft diesel V-6 at the rear. Pushing the scales at 3,196 pounds, the Audi e-tron Spyder accelerates zero-to-62 mph in 4.4 seconds and on to a governed top speed of 155 mph. The concept can run on electric power alone for 31 miles at speeds up to 37 mph. If those limitations don’t suit your needs, the power of the V-6 can be called upon for extra range and motivation. Audi estimates the e-tron Spyder at a combined 106 mpg. View more pictures of the Audi e-tron Spyder concept here.
Audi unveiled the first e-tron concept at the 2009 Frankfurt Motor Show and promised that it would, if demand was high enough, put 1,000 units into production. Two months later, Audi notified the motoring public it had plans to produce a whole range of e-tron vehicles. In total, Audi has showcased three other concepts wearing the e-tron name: two e-tron concepts and the A1 e-tron concept, so you can guarantee that at least part of the e-tron range will make it into production.
The original e-tron concept used four motors and one battery to produce 3,319 lb-ft of torque (although Audi says that the actual figure is closer to 502 lb-ft ). The car tipped the scales at 3,527 pounds, had an estimated range of 154 miles, and was able to muster a zero-to-60 mph sprint of 4.8 seconds.
A second e-tron concept introduced at the 2010 Detroit Motor Show was slightly smaller, weighed considerably less, and used two electric motors instead of four for a total output of 204 hp and 1,955 lb-ft of torque (Audi has not confirmed a real torque figure for this car). The 3,000-pound car was good for a 5.9-second rush from standstill to a 60 mph and a range of 155 miles.
The A1 e-tron concept unveiled at the 2010 Geneva Motor Show was a more down-to-earth iteration with a lithium-ion battery providing 30 miles of propulsion before relying on a Wankel engine to extend that range an additional 100 miles from a three-gallon fuel tank. The single electric motor produced 61 hp and 111 lb-ft of torque, although those numbers could increase to 102 and 177, respectfully, for short bursts. Acceleration was not brisk, requiring 10.2 seconds to get up to 60 mph from a stop.
