British luxury carmaker Jaguar has unveiled the 2014 XFR-S sedan at the 2012 Los Angeles auto show being held in the US.
The new sedan is powered by 5L supercharged V8 engine, mated to an eight-speed automatic transmission with Quickshift technology, which will generate an output of 550hp and 502lbft of torque.
Claimed to be the carmaker's fastest and most powerful sedan, XFR-S will sprint from 0-60mph in 4.4 seconds, while achieving a top speed of about 186mph.
Jaguar Global Brand director Adrian Hallmark said: "In the XFR-S that character has been amplified, the result being a truly engaging car with a combination of technical innovation, assertive design and staggering performance that will satisfy the most demanding of drivers."
Features of the sedan include recalibrated electronic active differential and dynamic stability control systems which are aimed at enhancing handling characteristics.
The carmaker will launch only 100 XFR-S sedans in the US from summer 2013.
