As others have said, Cd is the drag coefficient.

Hey! I just had a great idea for a low-budget movie! We'll need half a dozen jokers to play the highway patrol, half a dozen douchebags to play the drug-running local cops, a token cute girl, and Brian Cox to play the grumpy chief!

BMW already has a history of putting sensitive electronics near a heat source. Case in point: the BOSCH ABS/DSC control module in my E39 530i (and indeed other inline-six E39 cars, maybe other models too) that was mounted too close to the engine with insufficient heat shielding, necessitating a $1200 replacement…

For race- and performance-oriented cars, the 'Ring is probably best. But for regular cars that normal people buy and use every day in the real world, Los Angeles. Traffic, heat, crappy roads, fender-benders, stoplight dashes, etc. make it a perfect real-world testing ground. Plus, there are already leventy billion…

Cayenne video at 0:20 - watch it closely. It doesn't swerve to avoid the truck, it teleports past it.

Is the camera there only for parking purposes? It would be cool if you could activate it at will for another view of your high-speed jaunt through the desert. Bonus points if you can record video to an SD card or USB drive, but somehow I doubt any auto manufacturer would include that feature as it'd be too likely to…

Oh my God. Really really nice work!

My bad. I thought I read something somewhere (maybe here) that said it was a turbo I4. Should have done my homework.

There hasn't been a true M3 since the E46.

BUT, while the 2011 Miata starts at $24k, the 305hp 2011 Mustang V6 starts at $22.3k and therefore my vote goes to the Mustang.

According to U.S. News and World Reports ([usnews.rankingsandreviews.com]), it's - you guessed it - the Miata.

Agreed. The front end is all 350Z.

I love that gif.

The torque-steering... *shudders*

I think the 430 is an all-around better-looking car. I wouldn't refuse a 458 if someone gave me one; I'd just turn around and trade it for a 430.

Was that wheelspin on the upshift at 120mph (0:31)??? Whoah.

Hell hath no fury like the AMG 6.3 V8.

If I had seen your posts before I wrote mine, I would have just plussed-one as well. There's an E39 M5 that lives in my apartment complex, and one day bumped into the owner as he was emptying the trunk and I asked him how bad the maintenance was. He said he's never done anything to it other than change the oil, and…

When I was a sophomore in college, that was my dream car. I swore that when I graduated I'd move back in with my parents, get a decent engineering job, and save every penny until I could afford one. My, how things change.
