Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.

We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.

It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.

And of course, there is a question of politics. Audi wants a gap between the base R8 and the V10-powered model. Fitting the more potent 4.0-liter would mean upping the power in the V10, which would place the top-end R8 a bit too close to the upcoming V10-powered Lamborghini Huracán.

We've reached out to Audi for a comment as to whether there's any truth to the Car and Driver report. As of publish time, though, we haven't received a response. Whatever the actual reason – or reasons – for keeping the 4.2 V8 around, we're just hoping the magazine is right. We're sure the turbo 4.0 would be a great engine in the R8, but our ear drums are particularly happy at the thought of this naturally aspirated, rev-happy eight-cylinder hanging on in today's increasingly downsized and turbocharged world.

      I dont know much about audi engines but is this the same v8 that in the RS5? I hear that is a spectacular high reving (8500rpm) NA V8 and i had heard the R8 had a lesser V8. So is the next R8 getting the RS5 V8?

      The reason all car manufactures goes to 4.0, is that China has huge tax for over 4.0 engines. You pay 50% more import tax and yearly for 4.2 than 4.0

      Thank god. The 4.0 TT is nice, but you can't beat the throttle response of an N/A engine.

      Aren't the V10 R8s and Gallardos almost exactly the same performance wise already? R8 beats a standard Gallardo to 60, but is about 5mph shy on top speed.

      In my opinion they should just skip the N/A V8. Seriously, a kid can pick up a used C5 Z06 for less than 20k bone stock and beat the R8 in a straight line, lol

      That 4.2L NA motor is PATHETIC. Anything less that the 4.0TT is a JOKE. Give the next Audi S4 the 4.0TT and I'll buy it.

      That is nothing but BS LIES from Audi. UGR, Heffner, etc are all running turbos on the Gallardo/R8 with ZERO problems. Only an uneducated idiot would believe Audi's lies. And, Ferrari, Porsche, Nissan, etc have no problem with throttle response on their turbo cars. Obvious marketing LIES like these insult our intelligence and the press NEED to call these companies out on their BS. That fact that the media allows GM to spew the ridiculous claim that their new A8 with a torque converter can compete with a DCT like the Porsche PDK is another example of BS LIES perpetuated by the media.

        >UGR, Heffner, etc are all running turbos on the Gallardo/R8 with ZERO problems Riiiiiiiiiiiiiiiiiiiiiiiiight, because aftermarket tuners totally test for all conditions possible the same way the manufacturers do during development. The fact that you think that engineers are lying is even more amusing.

        Check back with me when those tuners offer a car with a warranty as long and wide-ranging as Audi as well. It's easy to tune a vehicle when you don't have to be responsible for what happens to it thousands of miles and years down the line.

      Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Why - what happened? Is Audi dropping the price down to $20K so almost all of us can afford one? This only affects the 1% of the 1% who are car enthusiasts (or something like that). While I love a fast car as much as the next guy (more, actually), I'd rather hear that Subaru added 20 hp to the STI, or that MB dropped $10K off the CLA A45, or that the new Mazdaspeed 3 has been announced. So, sure, it's nice for Bill Gates, the insane Incognito guy who may want to beat up an R8 next, or maybe Zuckerberg. Sure as heck makes 0.00% difference to my life....

      They should of done V12 or V10 TDI in what should be called the R10.

      Given the lineage behind the R8 badge, Audi needs to find a way to get a twin turbo direct injection gas V8 in that car...

      Scratch those V8's, bring in a V12 turbo diesel hybrid!

      I am wondering how Audi are running into this problem, especially considering how tuning companies have twin turbo upgrades for the r8. I would think that Audi would be able to create a solution considering what the tuners have done. Then again tuners aren't held to the same regulations as car manufacturers.
