12 December 2005

DaimlerChrysler’s division has developed a series of test cars that a range of advanced and alternative-fuel gasoline and diesel hybrids, and electric.

These follow on the of the crosstown hybrid showcar presented at the Frankfurt auto in September.

The crosstown hybrid. The smart car prototype combines an motor (with an output of up to 23 kW) the 45 kW (61 hp) gasoline engine from the fortwo.

The result is a 15% reduction in consumption to 4.3 liters of gasoline per 100 (55 mpg US). The smart crosstown offers approximately 10% better (the production car requires seconds to accelerate from 0 to 100

The mild hybrid system start-stop capability as well as during acceleration and during changes.

Instead of using a automatic transmission and torque the smart crosstown works a manual transmission mechanism friction-disc clutch. The advantages of compared with a fully transmission lie in the much higher lower weight, more dimensions and lower production

However, unlike an automatic this principle causes interruptions between opening and the clutch for gear shifting. In the crosstown these are bridged by the motor. For a few tenths of a second it the propulsion power needed, harmonious, steady acceleration the whole gear spectrum.

smart fortwo micro A micro hybrid version of the fortwo uses a belt-driven generator in combination with the 45 kW (61 hp) engine to reduce fuel by 5%.

The micro hybrid version no regenerative braking, nor any tractive It does provide start-stop

With the micro hybrid the fuel consumption level of 4.7 per 100 kilometers (50 mpg US) is reduced by 0.25 to less than 4.5 liters (52 mpg In urban traffic, the smart micro hybrid uses a 13% gasoline.

The diesel hybrid combines a 20 kW motor with the 30 kW (40 hp) diesel The design is much the same as hybrid, with the electric providing start-stop functionality, assistance, shift delay and regenerative braking.

Because the car’s shift are bridged by the electric motor, it needs 17.8 seconds to from zero to 100 km/h. ten percent—two seconds—better than a conventional diesel drive.

fortwo cng. The bi-fuel of the smart allows drivers to between gasoline or natural gas The modular design of the fuel means that the entire natural gas tank (2 x 16 litres) and the tank (12 litres) fit in the car’s The volume of the car’s interior and compartment remain, as in the case of the drive model, unimpaired.

The car consumes approximately 3.2 kilograms of gas (or 4.7 liter of petrol) per 100 kilometers, it a range of 385 kilometers (239 km with natural gas, and 255 km gasoline. The gasoline model, a tank volume of 33 litres, on a purely calculative basis, some 700 kilometers without a stop.
