Styling cues are likely to come from the open-top Ciel sedan concept Cadillac (pictured) unveiled at Pebble Beach
last August, with potential powerplants to include a 3.6-liter V6 and optional V8. An eight-speed transmission and AWD option are also expected. With the ATS compact sedan arriving to take on the BMW 3 Series, Mercedes-Benz C-Class and Lexus IS
, and a new CTS to arrive next year in the same class as the 5 Series, E Class and GS, the flagship sedan continues Cadillac's offensive and is essential for the marque not only to make headway in car-hungry China but also to boost the brand's image in established markets.
