I'm guessing he's saying kph? Top speed aero limited to 146 or so I think.
With Top Gear taking too long of a break (heck, even the US series!), I've been trying to watch 5th Gear. I'm not getting in to it. It's not bad like that Car Show with Adam what's his face. But it's a bit boring? Jeremy power slides cars around with a huge grin on his face and proves nothing. 5th Gear tries it, and they turn it into a nerdy science thing instead. They just strip some of the fun out of it somehow. I can't explain.
And a 0-60 drag race with 450-500+ hp cars? It's all launch. They need to do 1/4 mile or 1/2 mile to show which car really has legs instead of which can get out of the hole the best.
