+BR2+: The day they stop making V8s will be the day I lose interest in cars. Nothing can beat that sound, engine and exhaust note of a V8 engine is music to my ears.

If the 911 gt3 RS gets a turbo, what becomes of the gt2 and gt2 RS?

Same, Charger is ruined, Its a great looking car, But should never have been a 4 door saloon, Dont even get me started on the Dart, Bmws M/// Division losing its high reving N/a engines n going Turbo'd and fake sound bullshite...Mercedes non 6.0L+ Turbo'd, Audi v8 to V6s, Ferraris Long history of N/a now getting Turbo'd, Fkn ZO6 SuperCharged and a 6.2 instead of a 7.0, Cadillac V6, Porsche losing interest in Manuals and thinking of Turboing the 991 GT3 RS...Pretty soon there wont be any V8s at all.

Its getting ridiculous.

@BR2+: I totally agree with you, I'm especially tired of legendary muscle cars being brought back into production as 4 or 6 cylinder, front wheel drive shadows of their former selves.

Man, screw these Turbo'd 2.0L V6s and Eco InLine 4s, Bring back the Big blocks, the 427s, 442s, 402, 376, 409, 425, 426 etc, Its fine if you want a engine like a smaller liter and displacement, But my god bring back the Soul, Bring back what made the car, The Car, The Benz 6.3 hell even the 6.8, Bmw Natural V8, Im so sick of this MPG bullshit.

They talk about giving the next M3 an InLine 4, And the next RS4 a V6? Cmon! Its fine if you want that in a lesser version, But it does not have to be all the time

@ Shaggy. This 427 was a stroked 409 "W" engine. Not the 1965 and up Gen IV, 396, 427, 454 etc. Completely different block.

Those old school Impalas were beasts, not like todays Impalas, the ones Chevrolet builds today are pathetic.

Actually Chevrolet sold 57 of these beasts to drag racers. Aluminum hood, front fenders, brackets, and other lightweight stuff. No insulation, reduced backing for the bumpers, etc. Street legal, and frequently driven to and from the drag strip, but purposely engineered to beat other factory super stock drag cars.

I didn't think Chevrolet had a 427 until 1966.
