NHTSA probing coolant leak in Porsche 911?

In another embarrassing failure to understand what they're supposed to be regulating, the NHTSA has announced that they are investigating a “coolant leak” in Porsche 911s that were built with the GT1 engine block between 2001 and 2007. Maybe when they said coolant, they were talking about the oil that circulates in a 911 to keep the engine cool? Next thing you know, they'll be checking out fuel pumps on the Tesla Model S!

Hennessey Performance CTS-V wagon breaks its own record at the Texas Mile

Everything's bigger in Texas, and it appears everything's faster, too. John Hennessey and his company, Hennessey Performance, brought its tuned-up, 707-hp Cadillac CTS-V wagon--a.k.a., the Hammer Wagon--to the Texas Mile and posted a one-mile speed of 189.7 mph, a new record for the car. And that wasn't even terminal velocity, according to Hennessey.

Koenigsegg Agera R World Speed Records now official (video)

Koenigsegg Agera R gets Guinness World Speed Record - Video One of the speed records set back in September by the incredible Koenigsegg Agera R has now been ratified by Guinness - 0-300-0 km/h (0-186-0 mph) in 21.9 seconds. As we say every time Koenigsegg jumps in to vision with another bonkers car or speed feat, we’re amazed at just what a handful of men with beards (except Christian von Koenigesgg – who doesn’t seem to have a hair to his name) can do from a shed in the snow of Sweden. What makes Koenigsegg even more impressive is that it’s not just that they  produce a stunning looking hypercar, but that they do it all themselves.
