I've just briefly read through this article, which states that the new car uses the same old engine, but with 296bhp and a 20%increase in fuel efficiency.
"While the engine's 2.0-litre capacity is identical to its predecessor, it's been thoroughly reworked to produce an extra 35bhp and burn around 20 per cent less fuel - and the extra power is obvious, right from the off. Squeeze the throttle and after a brief pause as the turbo fills its lungs, the car punches forward with an urgency most hot-hatch fans won't recognise."
Question is, how is this achieved and can I mod my engine to gain the efficiency?
Thank you please.
