Audi has added its 4.2 FSI V8 engine to its R8 Spyder range.
The 424bhp, 317lb ft unit now completes the R8 Spyder range alongside the launch V10 powerplant. It is capable of taking the soft-top Spyder from 0-62mph in 4.8sec and go on to reach a top speed of 185mph.
The engine is mated to Audi's R tronic sequential manual gearbox; the R8 features permanent all-wheel drive through Audi's quattro system.
Like the V10 model, the V8 Spyder features an aluminium spaceframe with carbon composites and an automatic retractable folding cloth roof.
UK pricing and on sale dates have yet to be confirmed.
