When in China, stretch as the Chinese stretch. After Audi, BMW, Mercedes-Benz and Volvo, now it is Cadillac’s entry-level sedan who gets a long-wheelbase variation, so as to satisfy a local preference. The additional 85 mm increases both head and legroom for the back occupants and is almost unnoticeable from the outside. Everything else remains unchanged, including a feature list with ATS’s recently updated design, Brembo brakes, Magnetic Ride suspension, run-flat tires, the turbocharged SIDI 2.0L engine and even the 50/50 weight distribution.
