the only thing cooler than this was the BMW X5 LeMans concept years ago....

Any pictures of the interior? Mutec is realy good in modyfing the interior.

I like this better than the LeMans because it barely looks modified.

no, there's no way it's better, part of what you pay for is the look. They should have taken a 4.8is and worked from that body instead..more pictures would be appreciated if they are out there..

I would always take a plain jane exterior over a flamboyant one. There's nothing better than a sleeper.

Exactly. And it probably has a normal and practical interior. The X5 Le Mans had 4 bucket seats. Bucket seats have their place, but not in a car like this.

6.1L 450bhp. What the hell is wrong with them?

In a car like this it isn't about the bhp but torque that you want, the engine probably has a very smooth curve so even if you drive at low rpm, the moment you hit the gaspedal, the car will accelerate like hell...

So even it only has 450bhp for such a big engine, the bhp will be spread over the whole powerband.

I understand that but did not automatically assume it has lots of torque. The only specs given is horsepower.

So even it only has 450bhp for such a big engine, the bhp will be spread over the whole powerband.

If it has to spread between more mass then that means less bhp p/mass unit?

Not espacially, but most of the time, when european cars have a big engine (big in liters) and not that much bhp for it it's because it has more power underneath.

For example, the BMW E60 M5 has 507bhp for a 5liter engine (NA!), but it's competition, the Mercedes E55 AMG has 476bhp for a 5.4liter. But if you look at the curves of the car, you will notice that the AMG creates more power in lower revs, so, when driving both cars in a lower rpm at a higher speed (assume there are both manuals) the AMG will outrun the M5 the first meters.

Offcourse, this is all relative, cause when driven right, the M5 is faster. But in normal day use you can't always keep the revs up.

Also, in most of the time's, a lot of bph a litre is not good for the reliability of the engine. But that's in most of the time case of a turbo with to much pressure.

It would definitely surprise a lot of people if one was driven around here.
