Genesis initially offered the G80 with either a petrol or diesel engine, but has since decided to drop the 2.2-litre oil burner. The range now includes the original 2.5-litre petrol car alongside an all-electric model, which means business users, in particular, may wish to take a longer look at this impressive executive saloon.

In rear-wheel drive petrol form, the G80 will return average fuel economy of up to 33.9mpg, with the all-wheel drive model just behind with a figure of 31.2mpg. CO2 emissions are predictably high - ranging from 189g/km to 210g/km. If you were to track down a used diesel car, then Genesis claims you should see overall economy of around 45mpg.

Making a case for business users is a now a little easier with the Electrified G80 model. Previously, all versions fell into the top 37 per cent Benefit-in-Kind tax bracket, while fuel economy wasn't as competitive with rivals that employed some form of hybrid set-up. Now, the 364bhp all-electric G80 sits in the lowest tax band which attracts just a 2 per cent rate, while its official (WLTP) range is quoted at a useful 323 miles. Based on the same 800-volt electrical architecture as the GV60, the G80 can charge from 10-80 per cent in just 22 minutes.

Insurance

If you’re in the market for an executive saloon then you probably won’t be surprised that insurance premiums will almost certainly be a little more expensive than the norm. This is the case with the G80, as even the (now discontinued) 2.2-litre diesel Premium Line model is in group 40, while the top-spec 2.5-litre petrol Luxury Line sits in group 43. The more powerful Electrified G80 sits in the top group 50.

You will find other manufacturers, such as BMW and Mercedes, offer base models which have less power and are therefore likely to be cheaper to insure. The E-Class and 5 Series start from group 36 and 37 respectively, although move up to group 40 and above for the more potent versions.

Depreciation

Our data suggests that values for the G80 have softened just a touch over the last year or so; from holding on to around 44 per cent of its value after a typical three year/36,000-mile ownership period, the petrol model is now predicted to retain around 40-42 per cent over the same period, while the all-electric car is on 44 per cent.
