(Geometry and Functions in ‘N’ Adaptations)
The polyethylene-coated Lycra fabric is stretched across a mesh work formed from metal wires, with moveable aluminium structures electro-hydraulically controllable to allow the flexible fabric skin take on new shapes. The fabric can resist water, high or low temperatures and doesn’t swell or shrink.
The headlamps are hidden until the driver turns them on, only instead of popping up cheesily, like an ’80s Pontiac Firebird, the skin opens to reveal BMW’s traditional round lights. Not that anything needs to open to see the light; the turn signals and taillights operate behind the fabric, shining through when activated. The eight-cylinder engine hides under a 1.6-foot-long slit that opens and closes in a manner that BMW likens to the top of an old-fashioned doctor’s bag.

Speculations on the engine- turbo charged fuel injected v8-v10
(going buy size of the car and also looking at other BMW cars)
Considering the Gina's light weight and aerodynamic build the top speed should be very high
with a fast acceleration.

Have the German carmakers gone completely power-nuts? They sure have and nothing seems to be stopping them. New reports are stating that BMW has decided to pick up Audi’s (RS6) glove and introduce the 2009 M5 with a twin-turbocharged version of the current 507 Hp 5.0-liter V10 engine that could easily surpass the RS6’s 580Hp. MSN-Cars website supports that it may very well have proof of this through a series of spy pics featuring a faintly camouflaged BMW M5. And while one can’t be 100 percent sure of what we’re seeing in the spy pics, we can only think of one good reason other than that BMW is trying out its forthcoming DSG transmission, and that is a revised engine.

New 7 turning it up to 11
A sleek new 7-Series is being rolled out by BMW for 2009 and once again raises the bar for full-size luxury sedans. This fifth generation model will come in 750i and a longer wheelbase 750Li model, both of which will be powered by a new 4.4-litre twin turbocharged engine - the same one being used in the new BMW X6.
Other highlights include a 6-series automatic transmission, an entirely new suspension system, and several technologies new to the 7-Series including Lane Departure Warning, Active Blind Spot Detection and High Beam Assistance. High Beam Assist automatically turns off the high beams when an oncoming car is detected, and turns them back on once the car has passed.
The new-look 7-Series definitely sets itself apart visually from the previous generation model. It has new-look 'kidney grilles', front side panels that include a chromed 'gill' that integrates the side blinker, and a chrome band that connects the taillight clusters, which continue the L-shape that has become a BMW tradition.
BMW doesn't skimp anywhere, not even in the rear seats, where both left and right passengers will have their own climate controls. In addition, the long-wheelbase version not only adds more legroom for the rear passengers (140 mm.), it also provides more rear head room thanks to the model's own specific roofline. A special package available on the 7-Series also adds individual colour monitors to the back of the front seat headrests so the rear passengers can watch a DVD.
Driving dynamics are very much adjustable by the driver, from shock-absorber firmness and engine throttle response, to transmission shift characteristics, power-steering assist level and dynamic stability control mode.
An all-new (for BMW passenger cars) double wishbone front suspension is used in the 7-Series. It uses lightweight aluminum for links and other components, to help enhance the suspension's response and riding comfort over rough surfaces.
In terms of safety, the 7-Series makes use of the usual array of airbags (front and side impact airbags, front/rear head protection airbags, active head restraints on the front seats and knee airbags), but it also uses adaptive brakelights, whose lighting intensity increases the harder the driver brakes, warning vehicles driving behind the car. Once again the 7-Series uses night vision with infrared sensors, allowing the driver to see at night at lengths of up to 488 meters over a 36-degree-wide range.
The new twin turbo V8 develops 400-horsepower over a range from 5500 to 6400 rpm and 450 lb-ft. of torque over a range of 1750-4500 rpm. Quite the numbers, especially when considering the previous 7-Series' 6.0-liter V-12 develops 438-horsepower and 444 lb-ft. of torque.

The BMW hydrogen car is is BMW fist dual gas or hydrogen car put in production. The car is vary similar to the BMW 760Li in the way it looks and feels, even the engine is replicated but
modified to use both gas and hydrogen. Unlike other hydrogen powered vehicles made by other manufactures the BMW hyro 7 doesn't use fuel cell technology which uses hydrogen to make electricity but rather directly ignites the hydrogen in its internal combustion engine.
hydrogen vs gas energy
One of the problems associated with hydrogen is its low energy density and the amount of consumption it takes for power compared to (Gasoline 34.6 mj/l, liquid hydrogen 10.1).
another problem with hydrogen gas is the amount of energy needed to store it because in order
for liquid hydrogen to remain in a liqiud state it must be kept a vary cool temperatures ( below 253 °C (−423.4 °F).), and when fuel is not being usesed the tank warms and the hydrogen starts
to vaporize, and when the tank’s internal pressure reaches 87 PSi the tank will safely vent the building pressure. Over 10-12 days, it will completely lose the contents of the tank because of this.
