S60 replaces the boxy S70 as Volvo's midrange sedan. It shares a basic structure and many features with Volvo's V70 wagons, but doesn't offer all-wheel drive. A longer wheelbase and wider stance give the S60 slightly more interior room than the S70, but the new car is 6-inches shorter overall. All S60s have an inline 5-cyl engine; they come as the base 2.4-liter model, the more-powerful turbo 2.4T, and the sporty turbo 2.3-liter T5. Base and T5 use manual transmission or optional 5-speed automatic. The 2.4T comes only with automatic and includes a manual shift feature. Front side airbags, side curtain side airbags, and Volvo's antiwhiplash front seatbacks are standard. So are antilock 4-wheel disc brakes. The 2.4 model has 15-inch wheels and offers optional 16s. The 2.4T has 16s and offers optional 17s. The T5 has 17s. On T5, traction control is standard and an antiskid system is optional; both features are 2.4T options. T5 also can be ordered with a navigation system with popup dashboard screen.
