The 2005 Volvo S40 is a compact luxury sedan offered in three trims: 2.4i, T5 (turbocharged) and T5 AWD (all-wheel-drive). The base 2.4i model features a 168-hp 2.4-liter inline five-cylinder engine, while the T5 and T5 AWD trims receive a more powerful 218-hp turbocharged variant. Both engines pair with either a five-speed manual or five-speed automatic transmission. The S40 boasts a well-designed cockpit-like interior and standard amenities such as a CD player, steering wheel-mounted controls, and power driver's seat. Safety remains paramount for Volvo, evident in the S40's standard safety equipment that includes ABS, traction and stability control, and multiple airbags, culminating in praise for its safety ratings. A noteworthy feature is Volvo's Intelligent Driver Information System, which minimizes distraction by delaying non-critical alerts during intensive driving situations.
