Production of the Tesla Roadster may have ended but the pure-electric roadster model from Silicon Valley showed the way to other companies – and we mean that in the literal sense, as the PG Elektrus is an all too similar proposal.

Created by German manufacturer PG and Düsseldorf-based automobile designer Michael Fröhlich, the roadster model is once again based on the Lotus Elise and features an electric motor powered by a lithium-ion battery.

However, the Germans went one-step further and dressed the body in a carbon fiber suite to reduce the car's weight. Another highlight is the solar panel mounted behind the driver that collects the sun's energy and converts it into electricity to power up the batteries – or so the company claims.

Lotus is a brand with a long and distinguished history – yet that's not enough if your present situation is dire. In the first eight months of the year, Lotus sales were merely a blip in the UK sales chart as only 272 cars were delivered, a 24% decrease to the already depressing 358 units of the same period in 2010.

However, all we get is a boxer and a couple of fuzzy images of an undefined car. Lotus has stated that it will show three new models in Frankfurt, but has only named the Elise S as one of them.

Lotus is gearing up for the largest and most important automotive event of the year that takes place in Frankfurt next month with the presentation of three brand-new models, one special edition version and two new options for its current lineup.

The British company announced that one of the new models is the Elise S that replaces the Elise SC with a more capable 1.8-liter supercharged engine delivering 220-horsepower, while also returning lower fuel consumption and CO2 emissions.
