Seven new versions of the all-electric VW ID.3 range have been confirmed.
Cheapest is the ID.3 Life, which starts at £29,990 including a government grant.
Six will use a 58kWh battery and have ranges of between 258 and 263 miles.
The £40k ID.3 Tour with a higher-capacity 77kWh battery has a 336-mile range.
This puts it in contention with the long-distance Tesla Model 3, which is 7k more.
Volkswagen has also confirmed a number of cheaper variants for 2021 with smaller batteries and shorter ranges on a single charge.
Volkswagen has confirmed its first fully purpose-built electric family car will cost from less than £30,000... but only just, for now.
The current entry-spec ID.3 Life will be priced at £29,990, inclusive of the taxpayer funded grant of £3,000 paid towards the purchase of new battery-electric vehicles - though cheaper versions will arrive in 2021, VW has promised.
It has confirmed seven new variants of the Golf-sized plug-in car that will be available in the UK, with driving ranges of 258 miles to a Tesla-Model-3-rivalling 336 miles from the top-of-the-line £40,000 Tour edition.
The earliest cars on sale - called the 1st Edition - have been available to order since July, priced from £35,880 with the Government's Plug-in Car Grant subsidy.
First deliveries of these cars arrived on British shores at the beginning of September, though patient customers waiting for the UK line-up of specifications to be announced have had to wait until now to make their decision about which version to go for.
UK customers will be able to place their orders for these cars from 20 October, the German maker confirmed on Wednesday.
Six of the models - including the £29,990 ID.3 Life - use the same 58kWh battery and 201bhp electric motor featuring in the 1st Edition examples, while the top-spec ID.3 Tour has a higher capacity 77kWh battery.
It means that the six cars with the smaller of the two batteries have ranges of 258 to 263 miles, dependent on wheel size.
These versions will go into direct competition with the most affordable Tesla Model 3 sold in the UK, the Standard Range Plus, which currently costs £40,490 and has a claimed range of 254 miles.

The smaller battery will be able to receive 100 kW charging, which can boost it from 5 to 80 per cent charge in 35 minutes, providing around 180 miles of range.
From a standard 7.2kW AC socket, VW expects it to take 9 and a half hours to charge from empty to full.
The remaining variants are: Style, Business, Family, Tech and Max. All are tailored to offer slightly different styling and comfort packages to suit customers.
Commenting on the new entry price for ID.3, Tim O'Donovan, EV product marketing manager at Volkswagen UK, said: 'The ID.3 Life represents an affordable way for many people to take the leap into emission-free motoring.'
The priciest of all the ID.3s is the £39,290 Tour, which has a whopping official driving distance of 336 miles between charges.
This hauls VW's first purpose-built family electric car into contention against the long-travelling Tesla Model 3 variant.
The US firm's Performance and Long Range Model 3s have official ranges of 329 and 348 miles respectively - though the latter come at a premium of £16,500 over the comparative ID.3.
Only the Tesla Model 3 Long Range and pricier Tesla Model S - which starts from £75,000 - have longer quoted ranges than the electric VW.
The ID.3 Tour's bigger capacity battery can also take charge from 125kW devices, and a rapid charge can replenish up to 80 per cent in 38 minutes to provide an estimated 217 miles of range.
Next year, Volkswagen will introduce more specifications to the range, all of which will use a smaller 45kWh battery and will be priced below the ID.3 Life.
This should bring closer price parity between electric vehicles and a like-for-like alternative with a petrol or diesel engine.
The latest Golf Mk8 - which is very similar in dimensions and interior space to the new ID.3 - costs from £23,300 in the same Life trim, which is £6,690 less than the plug-in model. With cheaper variants in 2021, that gap will close.
As standard, all seven newly launched ID.3 models will feature LED headlights, adaptive cruise control, lane assist, VW's own Car2X communication system between compliant vehicles, voice control, parking sensors front and rear, and wheels no smaller than 18 inches.
Inside, all will have at least a 10-inch touch screen, keyless start and the ID.Light interior system that alerts the driver and passenger if there are any immediate risks.
