The new Shanghai-GM Cadillac SLS 2.0T SIDI is waiting for the crowds at the Guangzhou Auto Show. The new Caddy has a 4-cilinder 2.0 turbocharged engine with 263hp and 360nm, and that indeed is an Opel-engine. The 4-cilinder SLS is a China-only for now and will cost around 400.000 yuan when it hits the market early next year.
