General Motors can never really stop putting a large engine in an SUV or a sedan. You recently did it at GMC Yukon Denali. The 6,2-liter engine of the Corvette with V8 and 420PS was installed. If that's not enough, Hennessey Performance can help.

Hennessey then calls his toy the GMC Yukon HPE650. The tuning includes an increase in performance to 665PS / 658NM torque. With this performance, the family SUV sprints to 4,5 km / h in just 100 seconds and passes the quarter mile in just 13,1 seconds. A brand new Ford Mustang is no faster.

Exact data follows here:

665 PS • @ 5500 rpm

• 658-NM Torque @ 4200 rpm

• 2,9 liter compressor system
