Whenever we hear about a new Gran Turismo 6 (review) update, it invariably piques our interest as we know that a bevy of new concept cars are on the way.

As expected, the same goes for the driving simulator's latest update offering (1.17), with three new vehicles added to the Vision Gran Turismo garage. Also included is a fix to one issue found after installing the previous update, namely that Championship races in B-Spec mode could not be resumed.

Now onto the eye candy, with the Lexus LF-FC GT “Vision Gran Turismo”, Alpine Vision Gran Turismo and Alpine Vision Gran Turismo Race Mode all making an appearance. Let's run through the Lexus first, which is based on the LF-FC concept that debuted at the 2012 Detroit Motor Show. Designed to push the envelope as far Grand Tourer cars can go in the game, a cinematic CGI trailer has accompanied its release.

The Lexus is truly great to watch, but the two Alpine Gran Turismo concepts have certainly stolen the show in this latest update. GT6 developers Polyphony Digital teased their arrival a few months ago, and graciously decided to include in this latest update. Inspired by Alpine's Le Mans winning cars of the 1960s and 70s, these two new concepts look like a modern day interpretation of Speed Racer's iconic Mach 5. Click on video for these two in action.
