Modified Cadillac CTS-V Engine Fails at 218 Mph

This car raised the speedometer needle to its upper 200 mph line and kept it stuck there, its acceleration continuing, but the speedometer unable to correctly estimate speed anymore. So it took a GPS-based speedometer to record the 349 kph (218 mph) that this Cadillac CTS-V managed to achieve on German highways.

Naturally, it's not a standard Cadillac. It's a modified one that's got two huge turbos on the V8 under the hood, thanks to which it delivers around 1,300 hp (1318 ps).

The car accelerated with intensity on the German motorways, it made an absolutely fabulous sound, but all the pleasure came quickly and at a price, in the form of an open hood and the Cadillac stopped on the side of the highway.

The owner, however, wasn't too bitter, knowing the car's quirks, and even said he was preparing it for even more power.

This experience shows that it's not the provision of high power that's the problem, but the balance between high power and engine resistance with that increased power. Watch this Cadillac's incredible 349 kph run on German motorways in the video below. You might want to turn on the sound.
