2001 Chevrolet Corvette Convertible (C5). A major change from its predecessor the C4. the C5 featured a hydroformed box frame. a design that offered an improved structural platform. especially for convertible body style. The transmission was relocated to the rear of the car to form an integrated. rear-mounted transaxle assembly. connected to the all-new LS1 engine via a torque tube — an engine/transmission arrangement enabling a 50-50 (percentage. front-rear) weight distribution for improved handling. The LS1 engine initially produced 345 hp (257 kW). subsequently increased in 2001 to 350 hp (261 kW). This car also includes a newly installed top. and an upgraded sound system with a subwoofer in the trunk.
