Superformance’s Shelby GR-1 May Use Mustang GT500 V8 With Over 700HP

The road-going Shelby GR-1 that will be manufactured by Superformance could use the same supercharged V8 engine as the all-new Mustang Shelby GT500.

Superformance surprised the automotive world earlier this month when it announced that Ford had given it the go-ahead to put the iconic Ford Shelby GR-1 concept into production. At the time, Superformance chief executive Lance Stander said the vehicle will be offered in electric and ICE-powered guises, but failed to reveal more.

Now, Stander has indicated that the mighty V8 of the Mustang GT500 could make its way into the GR-1.

“The plan is a supercharged V-8,” Stander revealed to Robb Report.

“It sadly won’t be a V-10 [like the concept]. Ford doesn’t have a V-10 apart from one they utilize in trucks, and we want the GR-1 to be a production car with a production engine – all coming from Ford.”

Asked whether this engine is going to be the same mill as the one found in the GT500, Stander laughed and said “You’re thinking on the right track.”

If this is indeed the case, the GR-1 will have more than 700 hp on tap from the 5.2-liter supercharged V8. In all likelihood, the engine will be paired to the same Tremec seven-speed dual-clutch transmission as the GT500 and, of course, drive the rear wheels. Stander added that a six-speed manual version is also on the agenda.

Speaking about the all-electric version, Stander said that Superformance “simply can’t ignore the market’s move towards electric.” He also revealed that a hybrid powertrain is also being considered.

Superformance plans on building the GR-1 under the Low Car Volume Manufacturers Act, which will permit it to build up to 325 units. The order book for the vehicle has yet to be opened and the company says it has already received far more interest than it did in its Ford GT40 replicas built in 2005 and 2006.
