BMW has announced details for its i4 Gran Coupe, the electric car expected to arrive in 2021. It's a battery-powered four-door coupe set to come with BMW’s latest electrical powertrain meaning a range of 373 miles is being touted. Prices are yet to be confirmed but BMW has said that the all-electric i4 will be assembled at its production facility in Munich.

The race for electric car dominance is really heating up and BMW is planning on fighting its corner by having 25 electrified models on sale (or about to be on sale) by 2023. While this includes hybrids and plug-in hybrids alongside fully electric vehicles, 25 models is still a lot.

BMW has based the i4 on the 4 Series – and for good reason. For one, the 4 Series and 4 Series Gran Coupe are quite popular. For two, all those buyers who love their petrol or diesel 4 Series may well want zero emissions from their next car and a battery-powered i4 would be just the ticket. Finally, for three, from a commercial standpoint sharing platforms between cars helps minimise production costs.

Quick facts

  • Electric model based on the 2020 BMW 4 Series
  • Due to arrive in 2021
  • Maximum range of around 373 miles
  • 0-62mph sprint time of around four seconds
  • Up to 150kW charging
  • Electric motors produce 530hp

There are around 30 new all-electric cars set to arrive in the UK over the next 12 months, but few are direct rivals for a battery-powered Gran Coupe - BMW speak for a coupe with four-doors.

This doesn’t mean the i4 won’t have its work cut out in attracting buyers, a range of rather appealing all-electric SUVs and hatchbacks set to arrive in 2020 might just provide some competition – take the Ford Mustang Mach-E SUV for example, which is promising a maximum range of 370 miles.

2021 BMW i4 specs, prices and delivery dates

BMW is yet to announce which trims will be available with its i4, if any. Presently, the 4 Series Gran Coupe is available in Sport and M Sport guise, while the all-electric i3 is only available in one trim that doesn’t actually have a name.

What BMW decides to do with the i4 model range remains to be seen, but as the i4 will no doubt appeal to company car buyers BMW many well offer a variety of trims which ensure that the all-electric Gran Coupe works out well (re tax) for those lucky enough to get a car from their employer.

As for prices, these are again as yet unrevealed. Looking at what else is available, though, cars with ranges exceeding 300 miles and/or that sit in the more luxurious end of the market typically start around £50,000 to £70,000. For reference, standard petrol and diesel 4 Series Gran Coupe models start around £35,000. BMW has confirmed that production will begin in 2021 with deliveries following soon after.

2021 BMW i4 economy and performance

Claimed performance figures for the BMW i4 are impressive with a maximum power output of around 530hp expected. This, BMW claims, should allow for a 0-62mph sprint time of around 4 seconds and a top speed of 124mph. BMW is keeping torque and economy figures close to its chest, presumably while it puts the finishing touches on production models.

2021 BMW i4 range and charge times

As mentioned above, the BMW i4 is expected to come with a 373-mile range. Such an impressive figure is thanks to an 80kWh battery pack which comes as part of BMW’s fifth-generation eDrive technology.

BMW has stated that the i4 will be capable of handling up to 150kW charging points, meaning charging from 0-80% should take as little as 35 minutes. Naturally, charging from 7kW charging points (common for home charging points) will take significantly longer.

Anyone interested will be able to get a preview of the fifth-generation eDrive setup when the BMW iX3 SUV arrives in 2020, meaning the German car maker’s claims for range and charge times will have nowhere to hide.

2021 BMW i4 rivals and alternatives

As SUVs have done their very best to hog the motoring limelight, many of the new electric cars being launched in the next 12 months are SUVs or crossovers. As a result, the i4 isn’t looking likely to have many direct rivals.

The Tesla Model S is perhaps the closest thing to an exact alternative. The Model S is a saloon (which can be very similar in shape to a four-door coupe), comes with a maximum range of 379 miles and packs enough space for a typical family to motor around in comfort. When it comes to price the Tesla is not cheap, with the most “affordable” model starting at around £78,000.

Away from direct rivals there are a handful of SUVs, which, for those who don’t have their hearts set on a sleek coupe-esque body shape, will offer a largely similar ownership package when it comes to running costs and may even offer more in the practicality stakes.

First off, there is BMW’s own iX3 which is due to come with a range of around 250 miles and expected to cost from £70,000. Then there is the Volvo XC40 Recharge, which again is expected to come with a range of around 250 miles but cost a more affordable £50,000.

Audi is also set to offer an all-electric SUV-coupe in the form of the e-tron Sportback. This is expected to arrive in spring 2020 (the regular e-tron is already on sale) cost around £75,000 and come with a range of around 248 miles.

2021 BMW i4 interior and exterior design

Up until now, all of BMW’s ‘i’ models have come with very distinct styling – have a search for the BMW i3 and i8 and you will see what we mean. This is expected to change with the i4 thanks to the fact that BMW will use the regular 4 Series Gran Coupe’s body as the basis of the i4.

Even so, BMW is due to launch an updated 4 Series in 2020, meaning what the finished i4 will look like will remain a mystery for now. The interior is equally enigmatic, but other recently updated BMW models (such as the new 1 Series) give an indication of where the car manufacturer's interior design language is heading. What can be expected, then, is an increase in digitalisation (think more screenage and sharper graphics) plus a high-quality yet functional dashboard design.

Official dimensions are still being kept under wraps but buyers shouldn’t expect the i4 to stray too far away from the current 4 Series Gran Coupe. For perspective, a petrol 4 Series Gran Coupe currently measures in at 4,640mm long, 1,389mm high and 2,017mm wide (including wing mirrors).

2021 BMW i4 review

As the countdown to the UK's 2035 ban on the sale of all new petrol and diesel cars begins, the spotlight already shining on the electric car market is going to intensify. So cars like the BMW i4 are going to take on additional significance as we begin to get clearer picture of what we can expect the future of motoring to look like.

It's still very early days for this mainstream age of electric cars, but a 400-mile range would go a long way towards silencing steadfast critics of battery-powered motoring. We'll be on hand to deliver all the details on this upcoming car as and when they arrive, so check back for more news soon.
