When this Tucson's predecessor arrived in 2015, it wasn't particularly economical when fitted with a petrol engine or a 2.0-litre diesel, but Hyundai gradually improved the efficiency of its engine range. Over the years, a cleaner 1.6-litre diesel arrived, along with mild-hybrid assistance to recoup energy and take strain off the motor, as well as improving its stop and start capabilities in traffic.

For the latest Tucson, Hyundai has taken things a step further. Not only do more engines benefit from mild-hybrid tech, there's also a fully hybrid petrol for the first time in the car's history - this recharges a small battery using kinetic energy. A plug-in hybrid with a larger battery is also expected in 2021 to rival the Ford Kuga PHEV.

Hyundai Tucson MPG & CO2

The big news, at least for now, is the arrival of a petrol-hybrid Tucson to rival the Honda CR-V and Toyota RAV4 hybrids. This uses a 1.6-litre 'Smartstream' petrol engine and a 59bhp electric motor fed by a 1.49kWh battery. It's available with two-wheel drive and a six-speed automatic transmission, while non-hybrid models will also be offered with a manual gearbox. It can manage fuel economy of up to 49.6mpg, while CO2 emissions of 127g/km place it in a middling Benefit-in-Kind group for company-car drivers.

Stepping away from the full hybrid, there's also a range of 48-volt mild-hybrid petrol engines based on the same 1.6-litre. These come with 148 or 178bhp and either Hyundai's Intelligent Manual Transmission (IMT) or a seven-speed dual-clutch automatic. IMT can disconnect power between the gearbox and engine to allow it to temporarily turn off while the car is coasting, saving fuel. The IMT version with 148bhp can return up to 42.2mpg, with emissions of 148g/km. The 148bhp petrol is offered without mild-hybrid or the IMT gearbox as a budget option, aimed at private buyers with low annual mileages. This version returns 41.5mpg with CO2 emissions of 151g/km, making it a expensive option for business drivers.

Drivers with a higher mileage are offered a single 1.6-litre CRDi diesel, also equipped with 48-volt mild-hybrid hardware. It comes exclusively with front-wheel drive and a manual gearbox.

Insurance groups

Insurance groups haven't yet been announced for the latest Tucson, but they shouldn't stray too far from the ratings of its predecessor, which spanned from 12 to 25. While there's no 2.0-litre diesel this time around, we expect the powerful hybrid and plug-in hybrid versions to occupy fairly high bands.


While it may not match the seven-year warranty of Kia or SsangYong, Hyundai's five-year and unlimited mileage warranty isn't to be sniffed at. This is one of the most generous standard warranties in the business, beating rival offerings from Ford, SEAT, Vauhxall and Volkswagen hands down.


Buyers can choose a 'Hyundai Sense' fixed-price servicing scheme, with either a fixed price upfront payment or monthly charge covering all maintenance. This way there should be no surprise bills, and prices during the period of cover won't go up with inflation.
