Think of the T5 as the high-end trim in the S60 lineup. The T5 has a 2.4-liter, 257-hp inline five engine with a five-speed automatic transmission. Gas mileage comes out to 18 mpg in the city and 26 on the highway. The T5 offers more standard features than the two 2.5T trims, including a sunroof, air conditioning, power windows, power door locks, and power/leather seats. If you want a little hot sauce on your normally bland Volvo S60, you should spend a little extra to pick up this stronger, faster trim.
