Perhaps it would make most of its torque midrange, but that doesnt mean it wont make more Power at the top end, even if torque is tailing off.

I'm impressed they can make that much power, that they only have to rev to just over 5000rpm, they can get from 70-215 in 10 seconds and can a water temperature of just 76 degrees.

This lot need to show the masses of VAG engineers who built the Veyron how it's done.

Or more likely, it's all total bull..................
The engineering achievement of the Veyron was to build a reliable car that any unskilled, rich, show off can do 200mph in. If you don't care so much about driver friendly handling and can tolerate more frequent drive-train rebuilds there are hundreds, if not thousands, of cars built in sheds that are faster than a Veyron.

I have no trouble believing Hennessey have built a car that can accelerate like that despite their occasionally flaky reputation. If you want to do it more than a couple of times or put in a fast lap without skill on par with Walter Röhrl it might be a different story.

Correct. Obviously the headline figures are always going to grab the attention and stick in the mind, but the Veyron is so much more than just figures. Your granny could probably drive a Veyron to the South of France and back, in absolute comfort. The same couldn't be said of the Venom. Therein lies the difference.

Having said that, I'd be interested to see how tractable the Venom is and whether it's an on/off type power delivery - which I suspect it probably is.

It may be an 'interesting' experience taking one around some damp oily UK roundabouts, with any conviction. smile

6k is probably the top end for all intents and purposes..if it makes peak power @5500 and it drops off at 6000 what would be the point of revving it to 7500? It's all just guess work mind

Where's your sense of adventure? biggrin .. It's like a Speed 12 or a Cerbera. Sensible man says Cerbera. I say speed 12. Just because too much is never enough. smile

Why would it be? It has over 6 litres spinning what are probably a pair of GT30s of some sort.

Just a wee dab of 'oppo, I reckon hehe

It may sound like I'm being hyper critical of the Venom, I'm not. I absolutely love daft stuff like this, but I'm equally savvy enough to realise that it's probably going to be a bit of a pig to drive.

Still, I'm very glad there's still folk out there building mental stuff like this yes

True, technically there's no reason why it shouldn't be tractable with such high capacity. Time will tell I suppose...

The capacity may be high compared to most cars, but it's still putting out around 200bhp/lire; it's not going to be short of torque at low revs, but it's still going to have a damned steep torque curve when those turbos come on song.

I think the 725bhp supercharged one is probably a bit more... sensible. hehe

70-200 in 10 seconds is "only" averaging 0.6g. Even assuming no down-force, I'm quite surprised it's traction limited at the point of the last gear change. I think mid engined RWD setups are usually good for about 0.7-0.8g of traction? It did look like he was struggling to put the power down though, which does beg serious questions of the setup.

Or have I calculated something wrong?
Maybe he's getting lots of aerodynamic lift at those speeds?

How long would it take for a Veyron to do the same?

I am guessing that the 0-60 times is terrible due to lack of traction hence the reason they are doing a 70 - 215mph.

Also are we sure some one didnt just stick a mph sticker over the kph tongue out

That would be a pretty poor design given that the S2 Elise in original form generates negative lift at both ends. hehe

Well as for the 70-215 run I believe it was limited by the track they were probably on covering 0-215 would require a lot of land and of course they can't do it in public. I am pretty sure this is the worlds fastest and quickest car now. I also think hennessey has a very good reputation and a pretty extensive hostory of making the already great cars simply amazing. If you get a chance google some of his vipers.
