Summary
The Genesis G80 is 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.
Genesis is a spin-off upmarket brand owned by Hyundai, and the G80, alongside the GV80 SUV, is its first foray into the European automotive market after successes in Asia and the USA.
You won’t be able to buy a Genesis at a traditional dealership; orders are delivered to the customer, and cars are collected from the owner for servicing over a standard five-year care plan, as the brand looks to provide an attractive premium ownership experience.
The G80 range offers 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 have a separate Expert Rating page for that model.
The Genesis G80 has recieved a wide range of review scores, ranging from excellent to mediocre, 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 explains. “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 concludes 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 January 2024, the Genesis G80 holds a New Car Expert Rating of B, with a score of 65%. It earns top marks for its safety rating, but its CO2 emissions are only average and it also scores poorly for media reviews and running costs. We don’t have any reliability data at this time, so check back again soon.

“If you’re looking for a capable and luxurious executive saloon that runs the class leaders close, then the Genesis G80 is a worthy alternative.”

“We’re surprised how close to the class-leading BMW 5 Series Genesis has got first time out. The G80 matches its German rival on quality and class, and offers a unique buying and owning experience and some tech that’s yet to filter through to BMW.”

“Stylish, well-made and packed with tech, the Genesis G80 is impressive. But the lack of a plug-in hybrid option will seriously limit its appeal to tax-conscious business buyers and, by the time you add the additional tech, it’s an expensive choice, even in this company.”

“The Genesis G80 seems, in so many ways, like a luxury car for those who’ve had their fill of so many modern premium options; who are ready for something that fits into their life a bit more easily and discreetly than they’re used to, but which defines them a bit less starkly than others might.”

“The executive saloon class is full of accomplished, established contenders, so it’s impressive that the Genesis G80 gets so close to the best in class.” (Andy Goodwin)

“The Genesis G80 is the South Korean firm’s top-end saloon and comes with a quality finish inside, but it’s not as spacious as top-end options.”

“Classy, well priced and well kitted, as well as exceptionally refined and understatedly good looking. The Genesis G80 has plenty going for it, allowing for the online-only and haggle-free buying process that could be a complication.”

“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. The exceptions being engine refinement, the interior materials and their construction.”

“There is no doubt that the G80 is a worthy alternative to the class leaders in the sector and its overall package will be good enough to tempt some customers away from the big guns. It is a very capable luxurious executive saloon.”

“Sad to say, the driving experience like the interior, lacks a little bit of character. It’s much better to drive it as its maker intended and you’ll learn the Genesis is consummate mile muncher.”

“As a line-in-the-sand car, the Genesis G80 is a good introduction to this new premium brand. It’s got a lot of work ahead to draw people from their BMWs and Mercedes-Benz – to cement itself as a successful alternative (Lexus) rather than a pointless failure (Infiniti). So, if you’re interested, try a G80, to see what’s in store. Chances are, you’ll be nicely surprised.”

“I actually preferred the Genesis G80 saloon to the GV80 SUV. It rides better, steered better and just is better. Let’s hope Genesis can make an impression over the next few years and not exit stage left like Infiniti.”

“The Genesis G80 has its strengths, namely safety and interior quality. It’s worth a look if you’re bored with the big-selling European alternatives. Just bear in mind that, objectively at least, the BMW 5 Series is a considerably better all-rounder.”

As of January 2024, 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.
