BMW Sauber F1.07

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

I "hear" that Renault were down to 0.003s gear changes, so with say...40 shifts a lap, that is a theoretical loss of 0.12 seconds a lap.

BMW's seamless shift could be quite significant, provided it is reliable. High expectations for BMW and Redbull over the coming two years

Boy, a lot of people really ragged on the Toyota for loking like the same old thing (I wasn't in that camp BTW) but this BMW and also the Williams look pretty uninspired to me.

The BMW has got a whole new front end, new monocoque, new nose, new front suspension. It also has a new engine cover and reworked sidepods...

... just look at it, compare it to the old car...

I thought that 0.003s was widely accepted as OK and anything less than that would constitute a seamless shift which is not allowed by the FIA. In other words, I thought that "seamless shift" was actually a "virtually seamless shift".

darksnape, i dare yo to find me one single comment where a driver says "the new car sucks". if he says its already fast, it means its ok. if he says it seems to have potential, it means that its slow but hopefully they can find some speed.

The way I look at it ....... The car does not stop moving when it's changing gear so the time saved will be nothing like 0.12 of a second.

The gain is tiny tbh, most of the fast shifting is done while slowing down so nothing gained there. Shifting up, well there are only a few areas on each track where the driver would be flat out and able to advantage of the near seamless shift...

The gain for a seamless shift has been quoted by most teams as 0.2-0.3s per lap. Its not just the gain in actual shift time, but the smothness of the shift means drivers can up\down shift mid corner where previously the car would have been unsettled. Plus the engien lifts less so the flow throug the port sisnt slowed asmuch, this improves power take up after the shift.


BTW has anyone else seen the new front wing from the track testing of the car (not the launch or initial runs of the car), not just the blended cascades on the endplates but the two element wing with a slot moulded into the centre section of the flap forming a three element wing. Now thats clever use of CFD.
