New Audi A1 to mimic VW Polo

Audi has an all-new A1 hatchback on the way (but it won't be at next month's Geneva motor show) and it's gunning for the MINI.

No, not that MINI. The bigger one. The one with five doors.

That's because the entry-level model of the entry-level Audi is about to score more entry points, after the axing of the three-door model.

If you think this is a playbook you've seen before, you're probably right, because the Volkswagen Group twins the A1 with the Polo, and this year's all-new Polo has also dumped the three-door model.

Audi will launch both a new A1 hatch and new Q3 crossover later this year. The A1 will move from the 17-year-old PQ25 architecture to the smallest version of the Volkswagen Group's latest MQB platform, the MQB AO.

And squarely in Audi's crosshairs for the second-generation A1 is MINI, which insiders admit means the new car will need a big jump forward in handling, comfort and refinement. And, evidently, size.

The A1's chassis roommate, VW's 2018 Polo, last year grew 81mm to reach beyond the four-metre barrier and so will the A1.

The Polo's wheelbase grew 91mm to 2564mm and it's expected to share that number with the A1 to give the rear-seat passengers another 9cm of legroom.

The Polo also added 62mm of front track width and 49mm in the rear-end and its tyre sizes grew from 14 to 17 inches, all of which should be reflected in the A1's layout, along with about 25 per cent more luggage capacity.

Given that the A1 is supposed to be the more premium model of the pair, insiders insist it will have optional mechanical equipment the class has never seen, including adaptive damping, stronger gearboxes and new engines.

Both the Polo and the A1 will be built on the same production line at Seat's Spanish plant at Martorell, near Barcelona, with the Audi scoring a near full-width single-frame grille to make it easily distinguished from its cheaper sibling.

While moving to MQB seems expensive, it's a short cut to electrification for the A1, allowing easy access to mild-hybrid power systems and plug-in hybrid powertrains, too, though the Polo has shied away from both systems.

It will score the latest versions of Audi's fully digital Virtual Cockpit, which includes a larger screen and the option of a touch-screen for the infotainment unit in the centre of the dashboard.

It's a lock to suggest the car will have Apple CarPlay, MirrorLink and Android Auto, especially given the younger audience it's targeting with the car, while it will also use 4G LTE and WLAN for car-to-infrastructure and car-to-car communications.

The engine choices will neatly reflect what the Polo has, with a bit more power here and there. The entry level will be a new version of the 1.0-litre three-cylinder turbocharged petrol motor, while the new 1.5-litre turbocharged four-cylinder petrol engine boots the old 1.4-litre engine out from beneath the bonnet.

There's already a Polo GTI, so Audi has committed to a faster S1 with a 2.0-litre turbocharged four with about 230kW of power. It will be all-wheel drive, a grip-chasing idea that Audi will at last sprinkle through other engines in the range — at a cost.

The next A1 entered conceptual planning with ideas for a wide range of diesel engines and moved towards pre-production with just one — the same 1.6-litre turbo-diesel it had before.

Volkswagen's head of development has admitted before that it would not invest in developing any all-new small diesel engines, so this makes sense.

Manual gearboxes will be the standard equipment — at least in Europe — though seven-speed dual-clutch transmissions will be optional across the range.
