The most noteworthy element with this next-generation S40 is the sculpted shoulder line that starts at the front of the car between the headlights and grille and is carried across the beltline all the way back to the taillights. The new Volvo will be available with two new gasoline engines, the 2.4-liter five-cylinder with 168 hp and 170 lb-ft of torque, and as the T5 with the 2.5-liter low-pressure turbo with 218 hp and 236 lb-ft of torque.

The S40 T5's engine is the familiar 2.5-liter twin-cam, low-pressure turbocharged, intercooled in-line five-cylinder found in most other Volvo lines. Its 218 horsepower (at 5000 rpm) and 236 lb-ft of torque (between 1500 and 4800 rpm) have almost 750 lbs less car to move than the similar engine in an S60 2.5T AWD.

The S40 is offered in two different five-cylinder engines, the 168-hp 2.4L gas engine and the 218-hp 2.5L turbo gas engine, badged 2.4i and T5 respectively. The T5 is available in 2WD or AWD mated to a five -speed Geartronic automatic transmission or a six-speed manual. Standard features include cruise control, alloy wheels, daytime running lights, and an AM/FM stereo with CD player. The T5 trim upgrades by adding a trip computer, front fog lights, automatic climate control, a power driver's seat, and interior wood trim. The optional Climate Package, available on both trims, equips the S40 with heated front seats, rain-sensing wipers, and headlight washers.

Other features of the Volvo S40: Stability and Traction Control (STC), Available Electronically Controlled All Wheel Drive, the Volvo S40 T5 and T5 AWD offer a transversely mounted, 2.5-liter, 5-cylinder turbocharged engine with 218 hp, Ultra-Slim Center Control Panel, 6-speed manual transmission on the S40 T5 and T5 AWD, Intelligent Driver Information System (IDIS).

The new Volvo S40 has the safety equipment that includes dual stage airbags, side airbags, WHIPS (Whiplash Protection System), collapsible pedals, seatbelt pretensioners for the front and rear outer seats, and a force limiter for the front seatbelts. The S40 has anti-lock brakes and emergency brake assistance, while ESP and traction control are also available.
