Back in 1990 the FIA made a pivotal change to Group C regulations when they made the switch from unlimited displacement engines with limited amounts of fuel to the specific displacement of 3.5 liters and naturally aspirated but with an unlimited fuel cap, essentially giving Group C cars Formula One-like power plants.

While the new version of Group C enjoyed strong manufacturer involvement from the likes of Mazda, Nissan, Peugeot and others, because of this sweeping change it made older entries in the class uncompetitive. This in turn made Group C cost prohibitive to many privateer teams, and along with a new format that alienated many endurance race fans with races lasting a duration similar to F1, Group C began a rapid decline by 1993 due to a lack of entries.

But before the walls came crashing down, a handful of manufacturers created new racers to run in the series, including this incredible XJR-14 built in 1991 for Jaguar by TWR. Utilizing the same Ford V8 engine the Benetton F1 car, the XJR-14 boasted an aluminum honeycomb and carbon fiber monocoque, pushrod suspension, carbon brakes and an advanced aero system that all contributed to making the Jaguar the car to beat in Group C – but few could do so.

This particular example was originally raced by Derek Warkick and Martin Brundle, and here it is mixing it up (and battling for first position with a Jaguar XJR-16) on the Monza Circuit for the 2015 Coppa Intereuropa historic weekend earlier this summer in full 1080p, 60fps glory.
