2015 Volkswagen Jetta facelift price & specs – costs from £18,815

The facelifted VW Jetta is now on sale in the UK The Volkswagen Jetta – a VW Golf with a boot – is getting a bit of a facelift for 2015 (although you’d be hard-pushed to see the changes) and now, after its reveal at the New York Motor Show in April, it’s going on sale in the UK. Although the cosmetic changes to the Jetta are minor – the usual tweaks to the back and front, including a revised grill – VW claim the small changes it’s made result in a Jetta that’s ten per cent more aerodynamic (which makes you wonder why they didn’t do it earlier). The visual changes inside are just as minor, with a new steering wheel, new trims and new fabric options, with ambient lighting fitted to the Jetta GT.

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.
