ISC 2011

The IS C is the first-ever IS Convertible. A power-retractable three-piece hardtop folds into the trunk in about 20 seconds, among the fastest in its class [1]. Sharing few exterior components with the IS sedan, the IS Convertible has a striking silhouette, top up or top down. A double-wishbone front suspension and multi-link rear suspension are specifically tuned for the IS C. Standard 17-inch 10-spoke alloy wheels [2] and available 18-inch five-spoke alloy wheels [3] are also unique to the IS C. Combined with rear-wheel drive, the IS C is designed to offer excellent handling balance. Inside, the climate-control and audio systems are optimized for top-up or top-down driving. Heated and ventilated front seats with perforated leather are also available to help keep you comfortable no matter the weather.

On the technology front, an available Navigation System [4] with voice command can understand casual speech. The IS C is also equipped with several exciting technologies, including Safety Connect® [5] [6], plus available Lexus Enform® [5] [7]. Available SiriusXM services include SiriusXM Satellite Radio [4] [8], NavTraffic™ [4] [8], NavWeather™ [4] [8] and Sports and Stocks [4] [8]. Audio is enhanced with a standard USB input as well as Bluetooth® audio [9] connectivity for compatible music players, including iPod® [10].

IS 250 C models offer a 2.5L V6 engine with direct fuel injection for great performance and excellent fuel efficiency. It has MPG ratings of 20/27/22 (city/highway/combined) [11]. The IS 350 C model features a 3.5L V6 with both direct and port fuel injection, allowing it to produce 306 horsepower [12] for outstanding performance. Both engines have dual Variable Valve Timing with intelligence (VVT-i) for improved performance and fuel efficiency.

The IS 250 C is equipped with a standard six-speed manual transmission. A six-speed automatic with paddle shifters is available on the IS 250 C and standard on the IS 350 C.
