With its slightly higher power output but more weight to lug around, the G70 diesel gets very close to the 320d’s performance figures under similar dry conditions. Torquing the engine on the brakes in Sport+ mode activates a launch control function, which gets the car off the line very effectively and on to 60mph in 7.2sec. It also falls just 0.2sec short of its quoted 0-62 time of 7.4sec.
Those are respectable if unspectacular numbers, and that bears out subjectively, with the engine feeling willing and not sounding strained throughout most of the rev range but running out of puff a little at the top end. It’s not the quietest diesel around, sounding quite clattery on a chilly morning, but once warmed up, it didn’t bother our testers.
However, where BMW has the calibration of its eight-speed torque-converter automatic gearboxes down to a fine art, the transmission in the Genesis is a less willing accomplice to the engine. It shouldn’t have to be that way; the company develops its own gearboxes and the unit in the GV80 was near faultless.
In general, it’s perfectly smooth and responsive, but when you gradually ask for full power rather than matting the pedal in one go, the software can be reluctant to take the low gear that it should. Selecting the Sport driving mode doesn’t make much of a difference, while Sport+ will just keep the engine spinning 1000rpm too high in normal cruising.
