You'll have to look hard to spot the changes, but there are new bumpers, a new grille, different alloy wheel designs, LED headlights and some interior changes too. These include new seat covers, chrome detailing and extended smartphone integration. The highlight is a slimmer-looking 8-inch display screen, which helps with the Apple CarPlay and Android Auto systems in the cars.

The high performance Mercedes-AMG CLA 45 has been updated with extra power as well, bringing it back up alongside the A45 AMG with an impressive 376bhp and 475Nm of torque from its turbocharged four-cylinder petrol engine. That means 0-62mph takes 4.2 seconds in the coupe, with fuel economy of 40.9mpg.
The updates are for the Shooting Brake model as well, and include a tweaked grille and front bumper design, a new boot spoiler, a rear diffuser insert and an optional AMG aero pack that adds some extra fins and vents for a sportier look. There's also LED lights as standard, which were previously an optional extra.

There's also a new CLA Shooting Brake 180 BlueEFFICIENCY petrol, which has a 120bhp 1.6-litre engine that returns 51.4mpg.
Finally, you can now get a four-wheel drive CLA 220 4MATIC, which has a 2.0-litre petrol producing 181bhp with a seven-speed automatic gearbox.
