The best Spy Shots so far of the new Cadillac CT6 sedan. This is the China-made version, it debuted last month on the Chengdu Auto Show and will launch on the Chinese car market in early 2016. The Cadillac CT6 is be manufactured by the Shanghai-GM joint venture.

This is the CT6 40T, the Chinese designation for the new 3.0 twin-turbocharged engine. Output is 405hp and 543nm, and horses go to all wheels via a eight-speed automatic transmission. AWD badge on the lower-left. Shanghai-GM badge on the lower-right. Twin-pipes on each side.

The CT6 is set to compete with the lower-priced variants of the Audi A8, BMW 7, and Mercedes S-Class. It stands on the new GM ‘Omega’ platform that will also underpin a future big-barge Buick that will be manufactured in China exclusively for the Chinese market.

The CT6 will also be available with a turbocharged 2.0 four-cylinder with an output of 272hp and 400nm, sending power rear-wheels only. This variant will be designated ‘CT6 280’.

Transmission for bot engines is an eight-speed ‘Hydra-Matic’ automatic.

A very classy interior with loads of beige leather and rose-colored wood. Steering wheel looks brilliant with wood inlay and large Cadillac logo.

A mixture of analogue and digital. Nice for a Cadillac but still not on Audi or Mercedes level.

Start button on the left of the infotainment screen.

A speaker of the Bose Panaray sound system. This speaker is mounted centrally on top of the dashboard.

Elsewhere we saw a dusty wine-red example. The grille is hugely impressive with endless chrome and bling. LED strips of the headlights dive all the way down to the lower bumper where they connect with yet another chromed ornament.

This is the 280 turbo four. Twin-pipe on the right.

Got to clean her up!
