HAMBACH, France - The Smart car will be powered by a 0.6-liter, three-cylinder, turbocharged gasoline engine. The all-aluminum unit was engineered by Micro Compact Car in Renningen, Germany, and manufactured by Mercedes-Benz at its Marienfelde plant near Berlin.
The SOHC engine has two valves per cylinder, twin-spark ignition, an air-to-air intercooler and 32-bit electronic engine management system. It produces 55ps at 5,250rpm, and 80Nm of torque in a broad range of 2,000-4,500rpm.
The Smart has a top speed of 130kph. The car's overtaking ability has been improved by an 'overboost' feature.
This increases the turbocharger pressure momentarily, raising the maximum torque by around 10 percent.
The engine, called the Suprex-Turbo, weighs 59kg in production trim. It is mounted transversely under the floor at an angle of 481/4 and drives the rear wheels via a standard six-speed sequential transmission.
The Soft-Tip transmission is produced by Getrag, and allows Tiptronic-style gear changes without the need for a clutch.
The Smart's fuel consumption is nearly 30km per liter.
A direct-injection turbodiesel version incorporating Bosch's common-rail injection technology will be launched in March 1999.
