The mid-size S-Type luxury-sport sedan enters '07 with several new options, including a rear-seat DVD entertainment system with twin 7-inch LCD screens built into the driver and front seat passenger headrests as well as iPod and MP3 connectivity for the audio system. Base S-Types come standard, as before, with a 235-horsepower V-6 engine and the buyer's choice of either a five-speed manual or six-speed automatic transmission. A 300-horsepower 4.2-liter V-8 is the step-up option, and the high-performance R model continues with a supercharged version of the 4.2-liter V-8 delivering 400 horsepower. The R also gets the six-speed automatic transmission, upgraded Brembo four-wheel disc brakes, 18-inch rims (with 19-inch rims available) and Jaguar's Computer Active Technology Suspension system. A Luxury Package is also available for '07 on R models. All S-Types come with front side and side curtain airbags, traction control and stability control. Adaptive cruise control, heated seats and xenon headlamps are optional as are new 18-inch Triton wheels for the S-Type 4.2.
