Cadillac has revealed its big new CT6 flagship sedan in New York this week.
First revealed in late February as it rolled through the final frame of a Superbowl commercial, the CT6’s debut marks the next stage in GM’s plan to assert Cadillac as a genuine prestige brand.
As earlier teasers and leaks had revealed, the CT6's styling represents an evolved take on the angular styling that has set the brand apart since the first CTS debuted in 2003.
As a rival to the Lexus LS, BMW 7 Series, Mercedes S-Class, Audi A8 and Jaguar XJ, the CT6 enters the Cadillac range as an all-new and significantly more premium alternative to the existing XTS sedan.
And while the XTS is built on the older and widely utilised front-wheel-drive Epsilon II platform, the CT6 boasts a new lightweight rear-wheel-drive 'Omega' architecture
A total of 13 different materials feature in the Omega platform, with a full 64 percent of the CT6's structure made from aluminium. In fact, every exterior panel is aluminium.
Cadillac says that the new architecture means that the BMW 7 Series-sized CT6 weighs less than a 5 Series, which boasts a kerb weight of around 1600kg.
Importantly for GM, the new Omega architecture is expected to lead to four new lightweight platforms across the carmaker's wider range.
The CT6 measures 5182mm in overall length, riding on a long 3109mm wheelbase - a third of which is devoted to rear legroom alone.
Power in the CT6 will come from three engine options, including a new 3.0 litre twin-turbo petrol V6, producing around 300kW and 542Nm in its base form.
A 250kW 3.6 litre naturally-aspirated six will hold up the centre of the range, while an efficiency-focused 198kW 2.0 litre turbo four will open the line-up. Furthering the green cause will be a plug-in hybrid option, to be revealed later.
Rear-wheel-drive and all-wheel-drive options will be available, the latter offered as standard with V6 models. Eight-speed automatic transmissions are standard.
Other tech includes Magnetic Ride Control damping and an Active Chassis System with rear-wheel-steering.
Safety features include traffic crawl function, 360-degree camera view, night vision, video-equipped rear-view mirror, pedestrian collision mitigation and a parking assistant.
In the cabin, there's high-grade leather and wood trim, carbon fibre and aluminium highlights, reclining seats and 10-inch displays in the rear, 34 speakers, 4G LTE internet connectivity, wireless hotspot and wireless phone charging.
The CT6 will go on sale in the US later this year.
An reborn plan for launching Cadillac in Australia has been speculated in the past year, but GM has yet to confirm plans for our region.
