The same glorious-sounding, naturally aspirated, flat-six 4.0-litre engine as the Boxster Spyder but detuned to 395bhp, which will get you from 0-62mph in a rapid 4.5sec. But as well as its performance there's the engines smoothness and wonderful power delivery, which lets you build speed from low revs in sixth gear, or use all the near-8000rpm rev range for the true sports car experience. The six-speed manual gearbox is also a delight and it's not much less economical in the real world than the 2.5-litre Boxster S.
