The 2.4i carries a 168-horsepower five-cylinder engine while the T5 boasts a turbocharged 218-horsepower five-cylinder motor, both mated to a five-speed automatic transmission. Inside, the S40 features minimalist Scandinavian design with a 'floating' center stack. From a technology standpoint, you'll find a high-end audio system and automatic climate control. Volvo's emphasis on safety is evident with features such as anti-whiplash seats, stability and traction control, and optional side-curtain airbags.
