I was comparing sedans, but if you want to compare the ZR1 to another sports car, compare it to the 911 Turbo. The Vette gets 13/20 mpg, the 911 gets 15/25. The Vette's 6.2 liter engine gets it from 0-60 in 3.4 seconds, the 911's 3.8 liter engine does 0-60 in 2.9 seconds. The ZR1 is 97 dBa at full throttle and 80 dBa at 70 mph, the 911 is 83, dBa at full throttle, and 72 dBa at 70 mph. The flat six is just more refined, quieter, more fuel efficient and faster.

I always love 911 fanboys. 0-60 2.9 really? that's only with launch control ON without it slower than 3.4 0-60 second. Also have fun with those 0-60 in 2.9 when you blow your tranny and it's not under warranty since you used launch control too much

What's MSRP on a 911 turbo again yup 140k+, 4-5k of bolt-ons on that Zr1 you are blowing the 911 turbo out of the water with an extra 35k+ in your pocket.

Really a flat 6 TT is more efficient than a LS9/LS7 lol obviously not to mention all MPG tests the turbo is out of boost pretty simple to get MPG ratings low.
