In the latest episode of Fifth Gear, Jason Plato has a go in BMW's flagship convertible - the F12 M6 Convertible, boasting 560hp / 501 lb-ft torque from its twin turbo V8 S63Tu motor, but weighting in at 4,530 pounds.
Plato praises the power delivery and sound from the new S63Tu based powertrain. He achieves 0-62mph in 4.3 seconds for the M6 convertible in his test.
Although the car weighs in at 4,530 pounds, it never feels like it to according to Plato. There's a bit of understeer in high speed cornering, but that can be somewhat alleviated by more aggressive throttle application, albeit resulting in a harsh transition from understeer to oversteer. Overall, Plato feels the M6 is a great driver's car which delivers really good fun.
The review starts at 7:07 of the episode.
