"It pounces on corners, tracks flat through the apexes, and devours the straights with a burly snarl from the V-8. It laps up freeway kilometers at triple-digit speeds, the suspension digesting ripples and dips so thoroughly that the body remains almost inert. All the driver has to do is aim the 645 and it goes there. Fast." Sounds great, right? Absolutely, except for the fact that it isn't about this 640i. Keen BMW fans would probably be fast to note that this 640i doesn't even come with a V8. The above is fro m a review of a 645Ci that was published back in January 2004, 12 years ago. This new review , though, was.. let's be kind and say less flattering. As seems to be a pattern now for all BMW's, except the 2-series and M models, there's lots of disappointment. "Our car, equipped with BMW’s M Sport package, offered what seemed to be a slathering of faux sportiness." It only managed 0.86 g on Car and Driver's 300-ft...
Okay, this isn't a car but there's a reason why I'm writing about it. It has a supercharged 1.0 litre engine makes 296 hp. 296 hp may not be too impressive in a car but one has to remember that this isn't a car. It's a bike and it weighs just 476 lb in full trim and a 90% full tank. That's a weight to power ratio of 1.6 lb/hp. I'm having a hard time wrapping my mind around that number. To put that number into perspective, a 2013 Mustang GT500 has 5.9 lb/hp. A C6 Corvette ZR1 has 5.3 lb/hp. A 2015 Porsche 918 has 4.2 lb/hp and that's with the electric motors running at full song. The insane Hennessey Venom GT with its twin-turbo LS7 7.0 litre engine has 2.2 lb/hp. I can't even begin to imagine what 1.6 lb/hp would feel like. I would also be curious about how fast you'd have to be going to be able to use that power. I used to have an 09 Cobalt SS. It had GM Stage 1 and a few bolt ons which would put it at very close to that 296 ...
