Spearheading the return of a factory-backed SRT Viper Racing team to the American Le Mans Series (ALMS), the SRT Viper GTS-R is also intended to add a lot of halo effect to the SRT sub-brand under Fiat ownership.
The team is fielding two identical GTR-S cars, each powered by an 370kW/680Nm 8.0-litre V10 instead of the 477kW/813Nm 8.4-litre V8 that powers the street-legal versions.
