RUF Automotive producing electric Porsches for field tests

RUF Automotive, the German firm so adept at modifying vehicles they are considered a manufacturer, is developing electric Porsches for field tests this year. The vehicles will be produced in association with Seimens AG and adapted from 911 models. Data derived from testing will be provided the German Field Ministry of the Environment, who is sponsoring the trials.

The cars developed will test three modes of operation of interest to the ministry. The first utilizes a single motor and Porsche gearbox while the second is a two-motor variation with a 2-speed gearbox and limited slip differential.

The third of the 997 Carrera-based vehicles will employ twin motors and two gearboxes to create independent rear-wheel drive.

The single engine version will have a lithium-ion (LI) storage capacity of 29 kWh and will generate slightly over 240 horsepower. This will give the electric Porsche a top speed of 136 mph and a range of 93 miles. It can go from 0 to 60 in 7 seconds.

The second model will use transversely mounted synchronous motors and an automatic 2-speed gearbox. A temperature controlled LI battery is employed boosting capacity to 36.6 kWh. The car will have a range of 124 miles, an equivalent top speed and the ability to go from 0 to 60 in 5 seconds.

The third variation utilizes torque vectoring to provide independent drive from the rear wheels and also features the temperature controlled LI battery. This vehicle will have a top speed of 111 mph, equivalent range and will also get from 0 to 60 in 5 seconds.

The 10 examples of the three different variations will be ready for testing by the end of June.
