Diesel · 1,685 cm³ · 115, 136, 141 hp · since 2010

Verdict

A 1.7-litre four-cylinder diesel engine, fitted to the Hyundai ix35, Tucson and i40 and the Kia Sportage, Carens and Optima. Its most cited weak point is the particulate filter, which clogs in town use. Keep it for regular open-road driving and check that no warning light is on.
