- Lexus aspires to sell between 3,000 and 4,000 IS-Fs in the
United States in the first year, according to the Web site www.detnews.com. The IS-F’s direct-injection V-8 is the same basic motor under the hood of the Lexus LS600h hybrid limousine. The engine — co-developed with Yamaha — features titanium intake valves, hollow camshafts, better-breathing cylinder heads, and an extra oil-scavenging circuit to keep it all lubricated during high-G cornering. The unit cranks out 371 pound-feet of torque at a relatively busy 5,200 rpm.
The IS-F is equipped with an eight-speed automatic transmission. In manual mode, the lock-up clutch remains engaged in second through eighth gears, so that the automatic transmission behaves like a clutchless manual transmission.
