what is the difference between a volvo xc60 d4 and d5?
They both weigh about the same, so in the end it just comes down to how much quicker the D5 is compared to the D4. According to Volvo, the XC60 D5 will hit 100 km/h (62 mph) in 7.2 seconds, whereas the D4 needs 8.4 seconds, so on paper, there's no denying who's faster.
