The Audi R4 will be based on the Audi E-Tron presented at the NAIAS Detroi Auto Show, and will be the next couple sports model placed between the TT and the R8 in the Audi line-up. That’s not to indicate, though, that it will be like the original E-Tron seen at the Frankfurt motor show, as it will have quite a different body shape rather than being a modified version of the R8.
The Audi R4 will be equipped with both four and six cylinder TFSI engines combined with electric motors. The batteries located directly behind the cabin should guarantee better weight distribution than the original E-Tron, but will still remain faithful to the technical philosophy of four electric motors per wheel.
According to reports from the 2010 Detroit Auto Show, Audi could also extend the ‘E-Tron’ name to include a full range of electric vehicles, without differentiating among segments. This would follow the history of the ‘Quattro’ name in the 1980’s, and would create greater identity for this kid on the block.
