Cadillac STS

The £33,995 STS comes with one of the world’s most advanced V6 engines.  In its latest form, this 3.6-litre SIDI direct injection unit generates more power and delivers more performance while also achieving greater fuel economy with reduced CO2 emissions.

Maximum power is now up to 315 ps at 6500 rpm with 374 Nm of torque at 5200 rpm to deliver a powerful, typically Cadillac performance.  A driver-friendly 90% of the peak torque is available across a broad operating range from 1600 rpm to 5800 rpm.  In addition, an electronic throttle control (ETC) effectively ensures a crisp response to driver inputs.  With the V6 engine, STS reaches 60 mph in 6.9 seconds and can attain a top speed of 149 mph.

Cadillac’s Hydra-Matic electronically controlled automatic transmission incorporates Driver Shift Control (DSC).  This system gives drivers a choice of fully automatic operation or in DSC mode, sequential manual selection of gears by a quick tap on the selector lever.

For maximum traction, every Cadillac STS is equipped with an electronic traction control system (TCS) - which uses the ABS system to apply the brake on a spinning rear wheel - and a limited-slip differential in the rear axle, which operates automatically, full-time, and limits wheel spin.

‘Real time’ damping for optimum ride and handling

The STS rides on a fully independent suspension system which features aluminium double-wishbones at the front (to reduce unsprung weight) and sub frame-mounted multi links (some in aluminium) at the rear.  These integrated chassis technologies are optimised to combine high dynamic performance and a comfortable ride without sacrificing a rewarding driving experience.

While the front shock absorbers are high-performance dampers from German specialist Sachs, at the rear all STS models are fitted with Nivomat self-levelling dampers.  These units automatically adapt to different loads and road conditions to maintain a constant ride height, ensuring consistent handling characteristics - regardless of load.

The V8-powered STS model also features the award-winning Magnetic Ride Control (MRC) system.  The STS driver can select ‘Performance’ or ‘Touring’ mode for electronic control of the world's fastest-reacting real-time ‘active’ suspension system.  A set of sensors continuously monitors and adjusts the stiffness of the dampers (up to 1000 times per second) to reduce roll when cornering and squatting during braking, while also providing exceptionally responsive handling and the smoothest of rides.
