Lexus IS C
The all-new 2010 Lexus IS 350C and IS 250C hard-top convertibles give Lexus a coupe and convertible in the entry luxury segment for the first time. The IS C models combine the expressiveness of a convertible with the athletic styling of a coupe.
The IS250C and IS350C represent Lexus’ second convertible and its first since the debut of the SC430 in 2001. Featuring a convenient single-switch operation, the new three-piece hard top provides open-air freedom with the top down without sacrificing the quiet and comfort of a coupe. Constructed primarily of lightweight aluminum, the hard top also provides surprising storage space but with low noise and increased security not typically found in soft-top convertibles. In addition, the top completely retracts with no elements remaining in view.
The four-link roof assembly, also made of aluminum for a lightweight design, provides smooth even movement. Engineered to operate in an easy, efficient manner, each component is motor driven with detection switches, allowing the control unit to know their exact position at all times. In addition to the two main roof panels being constructed of light-weight aluminum, the back window’s reinforced glass construction also lends itself to reduced weight. Weather-strip changes in areas around the doors and windows ensure tight seals.
The IS convertible models feature the same powertrains as the IS sedans. The IS 350C's 3.5-liter V6 delivers exhilarating performance with outstanding 306 horsepower at 6,400 RPM along with 277 lb.-ft. of torque at 4,800 rpm. The IS 250C's 2.5-liter V6 engine has a great combination of fuel efficiency and performance. The IS 250C’s V6 produces 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. Both engines utilize aluminum cylinder blocks and heads, while employing dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.
A direct-type fuel-injection system provides a cooling effect in the cylinders, enabling the high compression needed to extract maximum energy from the fuel. Aside from its larger displacement, the 3.5-liter V6 differs chiefly in that it augments the direct fuel injection with port fuel injectors. In light- and medium-load conditions, these additional injectors help produce a precise burn, increasing power and efficiency, while reducing emissions. A dual exhaust system reduces backpressure at higher engine speeds. Like IS sedans, the IS250C and IS350C meet the Ultra-Low Emission Vehicle II (ULEV II) certification.
An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350C. The IS 250 C comes with either a six-speed manual transmission or the paddle-shift, six-speed automatic transmission.
