Volvo's compact-class cars consist of the S40 sedan and V40 wagon, each exhibiting styling points that look similar to the flagship sedan only in a smaller scale. The format amounts to a basic wedge-shaped shell with high-hiked tail and low-canted prow capped by the boxy chrome grille evident on all Volvos. Both sedan and wagon add up to the same external dimensions and ride on the same compact platform with a transverse-mounted front engine pushing power to the front wheels. Interiors configure differently behind the front seats due to a flexible seat arrangement in the wagon. The aluminum four-cylinder engine displaces 1.9 liters and earns a ten-point power boost to 170 hp. Extensive safety and security features line these smallest Volvos, such as frontal air bags plus seat-mounted side air bags. Also, Volvo's DSTC may be added. New equipment includes a keyless remote entry with folding key, LED lighting for gauges in the instrument cluster, slimmer head restraints to improve the view rearward, a new three-spoke steering wheel and leather-wrapped handbrake grip, plus the audio upgraded with CD and cassette players. Two new color choices also emerge: Silver Green and Maya Gold.
