Genesis GV70 Model Overview
2.2 Diesel
The 2.2-litre diesel engine provides excellent fuel economy and long-distance comfort. It delivers strong low-end torque, though it can develop diesel particulate filter (DPF) and exhaust gas recirculation (EGR) problems if used mainly for short trips.
2.5T Petrol
The 2.5-litre turbocharged petrol engine produces 304 bhp and offers quick acceleration and smooth performance. However, it may experience turbocharger wear or timing chain noise if oil changes are skipped.
3.5T V6 Petrol
This twin-turbo 3.5-litre V6 produces 375 bhp and delivers sports car performance in an SUV body. It is strong and refined, though high running costs and turbo maintenance are potential concerns.
Electrified GV70 (EV)
The electric GV70 has dual motors producing up to 483 bhp with Boost Mode and a range of around 283 miles. It is quiet and powerful but can face charging faults or heat pump failures.
