Alongside the Sonata Hybrid, Hyundai also unveiled the Sonata 2.0T at the New York Auto Show. As its name suggests, this is a Sonata YF with forced induction, and the unit in question is Hyundai’s 2.0-litre Theta II turbocharged GDI engine. Vital stats read at 274 bhp at 6,000 rpm and 375 Nm of torque from 1,800-4,500 rpm. The resulting performance should be quite amazing; Volkswagen’s latest 2.0 TSI in the Golf GTI makes 207 bhp and 280 Nm, and that engine is no slow poke.

With this engine, Hyundai will no longer offer a Sonata V6. Why? Because there’s no longer a case for one. For instance the Accord 3.5 V6 only makes 271 bhp and 339 Nm. Properly done downsizing is proving the old saying “there’s no replacement for displacement” wrong. Paired to Hyundai’s self-developed six-speed automatic (with steering wheel shift paddles), the 2.0T’s official consumption figures are 7.8 km/l in the city and 12 km/l on the highway, which is decent for the performance on offer.

Twin-scroll turbos have two exhaust gas inlets divided by split walls inside the turbine housing, with both gas passages controlled by a waste-gate (motor-driven in the Sonata’s case, for more precise boost pressure control). Its design separates the cylinders for improved pressure distribution in the exhaust ports and a more efficient delivery of exhaust gas energy to the turbine. Boost pressure is 1.2 bar.

Unfortunately for us in Malaysia, not only is there almost zero chance of us getting the 2.0T, Hyundai is reluctant to even bring in the direct injected non-turbo Theta II GDI due to our fuel quality. Perhaps they don’t feel the need to, as the Theta II in Malaysian bound Sonatas is already highly competitive against what the Japanese offer.
