Bosses at Audi have confirmed that the all-electric R8 e-tron is close to being signed off for production, meaning we could be seeing these revolutionary models in a showroom soon.
AOL Cars was lucky enough to get behind the wheel of the 380bhp mean machine last year to experience the shove that a mammoth 48.6 kWh battery cell provides when it is mated to two electric motors.
The results were impressive - the 0-62mph sprint took just 4.2 seconds and cornering was a doddle thanks to the awesome Quattro four-wheel-drive system and beautifully balanced chassis.
Despite this, Audi big cheeses were adamant that the R8 e-tron would never enter production, citing the fact it was too ex-expensive to produce (each prototype cost around £850,000) and that customers would be concerned about the limited range.
But Audi technical chief Ulrich Hackenberg revealed at the Detroit motor show that the battery technology of the R8 e-tron had been improved upon, making it more accessible to customers.
Hackenberg also said that plug-in hybrid technology is due to play an important role in shaping Audi's future – especially with the A3 e-tron just around the corner – so it is important the German marque has a flagship model in which to show off the technology.
