German marque Audi and Austrian motorcycle manufacturer KTM are working on a yet to be named Lotus Elise fighter, similiar to Volkswagen’s EcoRacer concept. The photoshopped artist’s impression above is based on the Pontiac Solstice.
Rumours are that a 2.0 litre turbo FSI from the Volkswagen/Audi stables will be powering the sub-750kg lightweight car. The light weight would likely mean a carbon fibre chassis, and that together with the 2.0 TFSI’s 200 horses and above of power will give the Audi KTM roadster a 0-100km/h sprint of less than six seconds, while maintaining good fuel economy.
Despite the 2.0 litre TFSI engine rumours, I personally think Volkswagen’s 1.4 litre twincharged engine is also suitable for this car, especially if it focuses on lightweight and fuel economy. A 1.4 litre engine would definitely be lighter than a 2.0 litre, allowing for easier engineering of weight balance. The current 170hp is more than sufficient for a sub-750kg car, and if that is not enough, 200hp versions of the 1.4 are on the way.
