Summary

The Genesis G80 was a large executive saloon that arrived in the UK in Autumn 2021, looking to challenge the likes of the Audi A6, BMW 5 Series and Mercedes-Benz E-Class. It was discontinued in 2024 as the brand shifted to 100% electric models.

Genesis is a spin-off upmarket brand owned by Hyundai, and the G80, alongside the GV80 SUV, was its first foray into the European automotive market after successes in Asia and the USA.

The G80 range offered two engine options to potential buyers; a 304hp 2.5-litre turbocharged petrol engine or a 210hp 2.2-litre diesel unit, both versions fitted with an eight-speed automatic gearbox. An electric version – called the Genesis Electrified G80 – is now available and we have a separate Expert Rating page for that model.

The Genesis G80 received a wide range of review scores, ranging from excellent to mediocre, with reviewers often singling out the saloon’s upmarket interior trim and the brand’s ownership care plan and warranty for particular praise.

“The Genesis G80 is an accomplished proposition with a distinct design, knockout interior, lots of well-integrated tech and a strong customer focus”, Car explained. “Unfortunately, that’s the opposite of the engine line-up, with a petrol engine that’s off the pace, a diesel whose time has passed, and no electrification yet.”

Company Car Today concluded its review by stating, “The Genesis G80 is off the pace in a lot of areas, such as tax, ride quality, headroom, boot space and efficiency, compared to established rivals.”

As of February 2026, the Genesis G80 holds a Used Car Expert Rating of D, with a score of 57%.

As of February 2026, we don’t have complete running costs for the Genesis G80. However, the data we do have shows that the G80 is an expensive car to own and run.

Emissions are average to poor, while insurance is expensive. We don’t have fuel economy data but, given the poor CO2 data, it’s unlikely to be good. We also don’t yet have servicing costs, so check back again soon.
