For this review, we had the S400d, which has the same inline 6-cylinder engine that has been used before, but with a twin-turbo setup pushing out 325 BHP and 700 Nm. There is also an S450 petrol on offer with about 360 BHP and 500 Nm. These specs, especially those of the diesel, will probably change for the CKD version, to something slightly less powerful.
