Standard equipment is so comprehensive that the factory options list has only two items – other than choice of paint finish, which includes nine solid, metallic, Tri-coat, Tintcoat, and ChromaFlair® colours. Option 1 is the power glass 'Ultra View' sunroof that covers more than 70% of the roof, giving both front- and rear-seat passengers a sky view, and costs £1,200. For £495 customers can specify Option 2, the 'Sapele Pommele' wood finish on the instrument panel, door trims and centre console.
The 3.6 model has all the features of the 2.8, but also comes with paddle shift controls for the six-speed automatic transmission, high-performance tuned self-levelling rear suspension, chrome finish for the 18-inch alloy wheels, dual chrome-tipped exhaust tail pipes, and voice activation for the infotainment system.
The new model is longer, wider and higher than the previous CTS, giving a more planted, well-grounded appearance. The wider stance is also accentuated by increased tumblehome, with the vehicle sides sculpted inwards to give a more dynamic appearance and a sleeker roof line, without compromising headroom or the spacious interior.
The 'tauter' more precise styling of the 2009 CTS is complemented by the larger diameter wheels and tyres which completely fill the smoothly flared wheel arches. Shod with low profile 235/50 R18 tyres, the nine-spoke, 18-inch wheels – with premium multicoat paint on the 2.8 and a high-polish finish on the 3.6 – are in turn packed with larger, high-performance brake callipers and ventilated discs.
The 2009 CTS cabin represents an evolution for Cadillac interiors. Advances in surface development, technology, materials and construction, all combine to highlight technical precision with elegant, hand-crafted details and precise tailoring. The centre console with a satin metallic finish sweeps smoothly into the low, laid-back integrated centre stack, providing a sporty 'cockpit' feel for the driver and passenger without compromising space. The tri-barrel analogue instrumentation, defined by bright chrome accents, is tightly framed with a compact cowling that adds to the car's sporting feel.
Interior comfort is further assured with dual-zone automatic climate control and cruise control. Clean, white ambient LEDs recessed between the upper and lower instrument panel combine with subtle illumination in the door pulls and footwells to create discreet theatre-style night lighting. Each of these features are standard on the new CTS which is offered with a single premium 'Sport Luxury' trim level specification.
A fully independent multilink rear suspension with isolated, 40% stiffer subframe on four rubber mounts provides maximum tuning flexibility and enables a superior ride/handling compromise to be achieved. The 2.8 V6 models are fitted with monotube Bilstein shock absorbers, while 3.6 V6 models have Nivomat self-leveling shock absorbers, which adjust automatically to different loads and road conditions. Both models are fitted with a limited-slip rear differential.
A high performance, all-disc braking system with ABS and traction control is standard. Large diameter, ventilated discs are fitted, front and rear, with cast iron callipers and twin, 42mm pistons (front) and single 45 mm pistons (rear). New CTS employs an electric push-button parking brake.
A further key safety feature is GM's Adaptive Forward Lighting system for the bi-xenon HID headlamps, which automatically adjusts headlamp direction for improved nighttime driving visibility. The system turns the headlamps up to five degrees inboard and up to 15 degrees outboard on each lamp. Safety is also enhanced by automatic rain-sense windscreen wipers with heated windscreen washer system and a rear park assist system.
