Concept Car of the Week: Chevrolet Express (1987)

A fantastic selection of concept cars from the ‘80s were featured in Back to the Future II such as the Pontiac Pursuit, the Ford Probe or the Saab EV-1, but my personal favorite was the Chevrolet Express that almost ran over Marty upon his arrival in the year 2015. Before being a movie extra, the Express was presented in 1987 as another attempt from GM to adapt aircraft engineering to automotive requirements. GM had been experimenting with gas turbines for more than 20 years, dating back to the 370hp XP-21 Firebird from 1954, but that concept was quite primitive compared to its younger brother.

Rinspeed to debut autonomous XchangE concept at Geneva motor show

Dutch coachbuilder Rinspeed has built a reputation for imagining and creating cars from 10 years in the future and making them a reality, either for well-heeled customers or for auto show crowds. So it came as no surprise when it revealed its newest project slated for the 2014 Geneva motor show, meant to preview the interiors of the self-driving cars of tomorrow. Yes, that's a Tesla Model S underneath with a (mostly) muted restyling of the front fascia, though it is really the interior that's meant to be the showpiece.

Lincoln MKR concept

By Tim Pollard Motor Shows 02 January 2007 11:49 Lincoln MKR Concept: the lowdown Lincoln will slide the wraps off its answer to the Mercedes CLS at the Detroit Motor Show next week: this luxurious and wedgy MKR concept. It’s the work of ex-Volvo British designer Peter Horbury, who now heads Ford’s Amercian design division, and hints at how Lincolns will look in the years ahead: the Viking-hat grille is straddled by pencil-thin LED headlights, while the flanks of the car are notably uncluttered. Don’t expect to see the 21-inch wheels and ‘Lincoln star’ patterns in the tyre treads on production cars any time soon, though.
