Due to be officially debuted at the Geneva Motor Show in March, the new upper-medium saloon is longer and wider than its predecessor, but is also lower and has a shorter wheelbase.
Gadgets available will include adaptive cornering headlights, a new electronic air conditioning system and automatic parking assist.
The safety has also been ramped up, and the car now has nine airbags.
Six engines will be offered, three petrol and three diesel.
Power will range from 105bhp to 260bhp, with either manual or DSG twin-clutch automatic gearboxes.
The exact UK line-up will be announced nearer to the launch.
It will go on sale in September.
