Article by Christian A., on August 29, 2010

It was announced today by UQM Technologies, INC., a developer of alternate energy technologies, that the recently released eRUF all-electric sports car is powered by a UQM Power Phase 150 electric propulsion system.

The eRUF electric-powered sports car was developed by RUF Automobile GmbH, a well-known producer of high-performance cars and maker of the celebrated CTR-series of sports cars.

eRUF Model A can accelerate from 0-100 km/h (62 mph) in less than seven seconds and has a speed ceiling of 225 km/h (140 mph).

Estimated effective distance per charge is between 250 to 320 kilometers (155 to 200 miles) depending on the performance level of the Axeon plc iron-phosphate, lithium-ion batteries that are at the core of the car's powerhouse.

Alois Ruf Jr., owner and chief executive of RUF Automobile GmbH, remarked that the PowerPhase 150 propulsion system installed in the eRUF Model A – with its impressive maximum torque of 650 Nm – puts a number of conventional combustion engines "to shame."

He said that the torque output of the UQM electric propulsion system could be compared to that of the RUF Rt 12. On the other hand, William G. Rankin, UQM Technologies' president and chief executive, said it was their pleasure to have its PowerPhase 150 propulsion system chosen by RUF Automobile to power the RUF sports car, the first electric-powered sports car from Germany.

The letter “S” (Sport) after the “911” model name has been known to indicate its designation as high-performance version of this already remarkable sports car.

In 1992 at the Geneva Motor Show, unveiled the 911 Turbo S of the 964 generation. This marked the first time that a model featured the letter “S,” signifying its position as the highest-performing version of the 911 Turbo. This 911 Turbo S was powered by a turbocharged engine that could deliver up to 381 of power output from its 3.3 liters of displacement. Technically, the 911 Turbo S was derived from the 911 Turbo that competed with success in 1991 in the Supercar Series, as driven by Hurley Haywood.

Distinguishing this 381-hp Porsche 911 Turbo S on the exterior are features like the flatter rear wing and side air intakes at the rear section. Compared to a typical 911 Turbo, the 911 Turbo S weighed around 180 kg (or 396 lbs) less, thanks to its level of equipment and special modifications.

The superior output level of the 3.3-liter turbocharged engine was thanks to modifications like upgraded intake ducts, a modified camshaft and increased charge pressure, as well as optimized ignition and injection system. With 381 hp on hand, this engine allowed the Porsche 911 Turbo S to sprint from zero to 100 km/ in 4.6 seconds and reach a top speed of 290 km/h (180 mph). With only 86 examples produced, the first 911 Turbo S had a price of around DM295,000 -- a fairly high price at the time.

In 1993, Porsche started offering the 911 Turbo S Le Mans GT as a genuine racing model designed to challenge GT-regulated long-distance races. Built by the Racing Department in Weissach, the 911 Turbo S Le Mans GT was sold to customer teams taking part in the new GT class in long-distance races. At the time, Porsche to equip the 911 Turbo S Le Mans GT with a 3.16-liter engine with bi-turbo technology. Despite its air restrictor, this engine is able to deliver up to 474 hp of output. Compared to the previous 911 racing cars, the 911 Turbo S Le Mans GT derives fresh air through the outer edges of the rear wing.
