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.

New SEAT Ibiza Cupra: Beijing 2012

2012 SEAT Ibiza Cupra The new 2012 SEAT Ibiza Cupra – called a concept but heading for showrooms – debuts at the Beijing Motor Show. SEAT are calling the Ibiza Cupra they’ve debuted at the Beijing Motor Show a Concept, but it’s not really a concept or a new Ibiza Cupra – it’s just the Ibiza Cupra with the updates the rest of the Ibiza has had for 2012. That means a bit of a nose job with glitzy new headlights with LEDs, new grill and big air vents, a revised bumper at the back with tweaks to the lights and some new alloys.
