The G80 launched with a four cylinder 2.2-litre 210PS diesel, with the alternative of a 304PS 2.5-litre four cylinder turbo petrol unit if you prefer to fuel from the green pump. Both are mated to an 8-speed automatic gearbox. Genesis has developed a 365hp all-electric version too, which gets an e-AWD system, can go up to 323 miles on a single change of its 87.2kWh battery and has solar roof panels to boost range.
The EV model's pretty silent, but even if you stick with combustion power we tried, you can expect exceptional levels of drive refinement, aided by special noise cancelling technology, along with acoustic-muffling side glass. And though this is no sports saloon, it's not slow, even the four cylinder diesel managing 62mph in 8.0s; you can trim two seconds off that time if you go for the 2.5-litre petrol variant. It's just 4.9s for the electrified model, which uses a powerful 272kW drive motor.
To replicate those figures, you'll need to have selected the most urgent of the three provided drive modes - 'Sport'; the other two are 'Eco' and 'Comfort', the latter best of course for experiencing the best that the standard Electronic Control Suspension system has to offer. Its adaptive damping effect is aided by a camera that monitors the road surface and adjusts the suspension to suit the tarmac tears and pot holes you're about to pass over.
You expect this car to be something of a luxury wafter and, sure enough, there's the rather light and woolly steering that tends to characterise this type of big saloon. Once we got this G80 to a few secondary roads though, we found that it actually handles better than we'd expected, though it's a pity that you can't have the e-LSD electronic limited slip differential that's available on the GV80 SUV model.
