The C70 is Volvo’s four-seat convertible coupe that returned to the lineup for 2006 with a new folding metal hardtop. The C70 originally debuted for the 1998 model year as a fixed-top coupe and a soft-top convertible, and began a new model-naming convention for Volvo: C denotes coupe, while 70 represents the car's relative position in the company's product line. The C70 coupe was dropped in 2003 and the C70 convertible continued for the 2004 model year before taking a hiatus in 2005. The 2009 Volvo C70 adds standard Bluetooth hands-free phone interface, aluminum inlay interior trim, leather sport gearshift knob with aluminum inlay, Volvo rear lettering spread further apart, power hardtop lowers and raises with one button and side windows automatically lower when top is lowered.
