GM's premium division unveils its new C-Class fighter, which gets CT6-inspired looks and a punchy twin-turbo V6. More details will come in New York.

Cadillac has revealed the all-new CT5 sedan, which will replace the ageing CTS in the brand's line-up.

Scheduled to make its public debut at the New York motor show next month, the CT5 sports a mini-me design drawing upon the larger CT6 – which will be retired at the end of the year – and will compete with the likes of the BMW 3 Series and Mercedes-Benz C-Class.

Full details will be revealed in New York, but at this stage we know the 'compact' sports sedan will offer a twin-turbo 3.0-litre V6 on higher-grade models, offering a beefy 420hp (313kW) and 430lb-ft (583Nm).

Cadillac says the V6 will get "unique sound calibrations", indicating it'll have some sort of sports system, enhancing its appeal to premium sports sedan buyers.

An entry-level 2.0-litre turbo four will be available, too, with both powertrains paired exclusively to a 10-speed automatic transmission. Rear- and all-wheel drive will be offered.

Two derivatives are showcased in the press images, the CT5 Sport (grey) and CT5 Premium Luxury (burgundy). Each have their own flavour, in both aesthetics and drive characteristics – with full details of both to be revealed in New York.

Inside, the CT5 features a driver-oriented dashboard layout which the company says "blends high tech and high touch for an exceptional blend of control tactility. We'll have to take their word for it, because the only image we have of the cabin so far is the one above showing the shifter.

From what we can see, the CT5 will feature a shift-by-wire wand, wood trim, lashings of leather and chrome, along with a rotary dial on the centre console – what in controls, however, is to be confirmed.

Stay tuned for our coverage of the full reveal at the New York motor show, which kicks off on April 20.
