New Bentley Continental GT Speed is the most powerful Bentley ever thanks to a new 771 hp hybrid V8. With the retirement of the W12 engine, Bentley are now moving into the hybrid V8 scene, and they have certainly delivered an impressive start on that front. The 4.0L twin turbo V8 has been combined with a 187 hp electric motor to produce a combine power output of 771 hp and 738 lb-ft of torque. Dubbed the ‘Ultra Performance Hybrid’, the power and torque boost should be useable across the entire rev range.
