Audi A1 2015 faceliftAudi has revealed a facelifted A1 and A1 Sportback range for 2015, boasting a typically understated set of exterior changes but much bigger upgrades below the surface.

Indeed, the revised A1 range packs a historical first for the Audi brand – it will use the firms’ first-ever three-cylinder petrol engine.

The new 1.0-litre TFSI produces 95hp and is capable of more than 65mpg – that’s 99g/km CO2, a first for a conventional-engined petrol-fuelled Audi.

It has a revised three-cylinder sister engine too, the 1.4-litre TDI: to ensure there’s still an efficiency advantage, Audi has improved average economy to 83mpg and cut CO2 emissions to just 89g/km.

All engines, says Audi, are either all-new or have been extensively revised. Power is up as much as even per cent, yet economy is improved by up to 10 per cent too.

Following the lead of other models, Audi now offers three types of suspension – regular, an interim sport grade and the stiffer S line Sport setup. Also new are electromechanical adjustable dampers.

Audi says the electromechanical steering system is entirely new too, with variable assistance and, if Audi drive select is fitted, driver-configurable steering weight.

Audi’s 2015 A1: super-subtle styling tweaks

Visually, the 2015 A1 is, well, almost identical to the old one. The headlights have been subtly reshaped, as has the front bumper, but this is, as with so many other Audi facelifts, minimal in the extreme.

The biggest standout will probably be some striking new colours.

Inside, Audi’s upgraded the MMI navigation system; it now includes Audi connect, so can hook onto the internet and has WiFi hotspot functionality so passengers can browse the net on their devices.

Much more MINI-style customisation and personalisation is now available, with Audi offering both more features and more options kits. There is smarter-finish chrome detailing to complement all these new trims and colour kits.

The new 2015 Audi A1 arrives in the UK from April 2015; ordering will open at British dealers later this month.
