Lexus has officially announced plans to introduce the 2014 IS at the North American International Auto Show in Detroit.

Recently previewed by the LF-CC concept, the production model promises to be "completely redesigned, inside and out." That's pretty vague, but the automaker recently gave Autocar a chance to drive a pre-production prototype.

According to the British magazine, the 2014 IS will ride on a shortened version of the same platform that underpins the GS. It will also have a revised suspension - with stiffer anti-roll bars and softer springs - and a luxurious interior that is heavily influenced by the CT200h.

In the U.K., two different engines will be available: an undisclosed V6 and a hybridized 2.5-liter four-cylinder that develops approximately 240 bhp (179 kW). The latter engine will be connected to a continuously variable transmission which should enable the sedan to accelerate from 0-100 km/h in approximately 6.9 seconds and hit a top speed of roughly 225 km/h (140 mph). In terms of efficiency, the hybrid could average 73 mpg UK (3.8 L/100km / 60.7 mpg US) with CO2 emissions of less than 100 g/km.
