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.

Porsche unveils 2015 911 Targa

Porsche has given its latest 911 Targa a heavy dose of retro appeal through the adoption of a series of classic styling cues that hark back to that of the original model launched in 1965. Unveiled at the Detroit auto show, the new 911 Targa is based around the same aluminium bodyshell and four-wheel drive mechanical package as the 911 Carrera 4 Cabriolet, alongside which it will be produced at Porsche's Zuffenhausen factory on the outskirts of Stuttgart, Germany. Among the traditional styling elements Porsche's design boss Michael Mauer has chosen to resurrect on the new car is a fixed B-pillar hoop, or Targa bar as it has come to be known over the years.

Bentley brings even faster Continental V8 S to Detroit

Bentley first showed the Continental V8 S at the Frankfurt Motor Show a few months ago, but the slightly more powerful V8 Continental makes its North American debut in Detroit. More horsepower is always welcome, and the handsome new grand tourer delivers precisely 21 more. While Bentley has been concentrating on W12-powered Speed models -- even suggesting that it might be an entertaining drive on a racetrack -- the V8 range has been bolstered by its own modest performance enhancements: 21 more horsepower and 15 more lb-ft of torque bring the 4.0-liter engine's figures up to 521 and 502, respectively.
