We tossed it over the back fence back in January, and now the UK web car daily AutoExpress has caught it. They've supposedly uncovered that Audi's made a decision on the deets for the oil-burning torque-heavy version of the supercar that we've been tweaking as of late. They claim the Brucegasmic automaker will drop the 4.2-liter V8 TDI engine that's currently powering the Q7 SUV into the engine bay of the R8. In The Q7, it produces 322 HP with 561 lb-ft of torque but AutoExpress claims this morning they'll be further tuning that engine up to 350 hp and 590 lb-ft o' torque. When hooked up to either the R8's six-speed manual or the six-speed R-tronic tranny, they're betting the R8 should be capable of about a five second 0-60 time with a top speed of 160 mph. But here's the kicker — it'll get 30 mpg. Both quick and fuel-efficient and wait, there's more — the diesel version supposedly will drop with a price tag around $30,000 less than the petrol version in Europe. Maybe we'll wait to spot the diesel version rather than the silly little gas one Audi has traipsing around town.
