BMW’s Green Sports Cars 2010

“It’s the sports car of the future, the way BMW imagines it.” That’s how Adrian van Hooydonk, director of BMW’s group design, describes the “BMW Vision Efficient Dynamics” two-door concept vehicle to be unveiled at the upcoming Frankfurt Auto Show. Think of it as a showcase of the many fuel-efficient technologies that BMW has in various stages of development. Some of the technologies already appear in production vehicles, while the feasibility of rolling out other systems stretch the future to the point of never.

BMW’s overarching goal was to combine breath-taking speed and groundbreaking efficiency. In the BMW Vision, that boils down to 4.8-second 0-to-60 miles per hour acceleration and 63 mile to the gallon.

First, BMW engineers use the rear-axle to combine a turbo-charged small diesel engine and the mildest forms of hybrid technology. That kind of combo comes standard in BMW 1-series cars in Europe. The Vision's setup is a little more similar to the BMW 320d, also to debut in Frankfurt, which uses a 2.0-liter four-cylinder diesel to deliver 162 horsepower, while promising more than 57 miles to the gallon. The BMW Vision takes it a step further by downsizing the engine to a 1.5-liter three-cylinder diesel engine mated with the more robust hybrid system found in the pricey BMW ActiveHybrid7, expected in the US early next year.

Not satisfied with 162 horsepower, BMW adds a second motor to drive the front wheels exclusively by electricity. When both motors and the diesel engine are called into service, the overall system can put out 356 horsepower. The BMW Vision is lightweight and aerodynamic. The design features an aluminum chassis and suspension, and an outer skin made mostly of polycarbonate glass. The car’s slippery design boasts a drag coefficient of 0.22—beating out the Toyota Prius’s 0.25.

To mitigate the fuel efficiency penalty paid for power, the BMW Vision utilizes plug-in hybrid technology. This is where the Vision becomes more of a fantasy. The combination of diesel and hybrid technologies is widely viewed as cost prohibitive. Adding enough battery power to allow the BMW Vision EfficientDynamics to travel for 30 miles of all-electric drive, as BMW is promising, would send costs through the roof.

BMW also indicates that the Vision only needs a 187-pound 10.8 kWh battery to achieve the 30-mile all-electric goal. To pull that off, the Vision, according to BMW, will discharge the battery pack's capacity by 80 percent, which is likely to significantly reduce the longevity of the battery. (The Chevy Volt will use about 50 percent of its capacity to help ensure a lifetime of use.)

Ferrari's latest the 458 has 570bhp and goes faster 2010

There are two things that Italy does better than anyone else: outrageous politicians and sports cars.

And while old Silvio has been up to his tricks, Ferrari has been busy building a fabulous new mid-engined sports car to replace the F430, itself a bit of a stunner.

The new car is called the 458 Italia. From the first bit of the name we can deduce that it's powered by a 4.5-litre eight-cylinder engine.

The new engine is direct-injection and has a whopping 570bhp at a screaming 9,000rpm.

It's more powerful than the F430 engine yet it is cleaner and more economical, not that economy is going to bother an owner that much.

What is important is driving slowly past nightclubs and attracting attention by blipping the throttle.

Many car companies claim to learn lots from racing and include the lessons in their road cars. Often it's just marketing talk but with Ferrari it's believable.

The Italia is full of hi-tech gizmos. For starters it has a seven-speed twin-clutch gearbox that changes gear faster than a blink, an electronically controlled differential and something called F1-Trac - a traction-control system that maximises acceleration out of corners without the risk of you flying off into a field.

The major controls are mounted on the steering wheel and by major we don't mean the stereo controls. Ferrari gives you a host of buttons to press that change the traction-control settings, throttle response and lots more. Just like on Raikkonen's F1 Ferrari racer.

As with the F430 the Italia's body and chassis is all aluminium, put together using aerospace technology including hi-tech glues. The Italia's dry weight is 1,380kg (a bit naughty that, as most manufacturers weigh their cars with oil and water in them).

A bloke called Michael Schumacher has played an active part in developing Ferrari's new sports car including helping to design the car's racer-like instruments.
