Volkswagen ID.4

This improved ID.4 GTX model gets the brand's latest APP550 drive unit, which has upped power to 340PS, 41PS more than this model had at launch.

And the sprint time to 62mph has improved to 5.4s.

Driving range has improved too - up from 309 to 319 miles.

Otherwise, the mechanical formula here is much as before.

Basically, the usual VW Group compact EV rear-driven formula is embellished with an extra motor on the front axle, which brings the twin benefits of extra power and, with torque at both axles, all-wheel drive.

Disadvantages lie with extra weight and a subsequent reduced driving range from the 77kWh usable-capacity battery compared to the single motor ID.4 model.

You'll find the same Dual Motor mechanical formula in top versions of the Skoda Enyaq and the Audi Q4 e-tron and their coupe spin-offs.

What's different here though, is that Volkswagen has lowered the suspension for hot hatch duties, dropping it by 15mm over the standard models.

Combine that with the XDS differential you get on a standard ID.4 for extra cornering traction and (if you pay extra) 'DCC' adaptive damping and the result is a surprisingly keen confection, aided by near-perfect 50:50 weight distribution.

Which is just as well given the fact that this car has to overcome the drawbacks of its enormous 2.2-tonne kerb weight.

That doesn't stop it being decently quick mind you.

And cornering is helped by 20-inch wheels with wide 235-section front and 255-section rear tyres.

You might be a touch disappointed to find that very little has been done visually to set this GTX model apart from its humbler ID.4 range stablemates.

But then if that bothered you, your dealer would probably point you towards the more eye-catching coupe-like ID.5 GTX model instead.

Anyway, to a lesser or greater extent, aesthetic subtlety has always been one of the attractions of this sub-brand's GTI parent bloodline.

It's cloaked here with a unique 20-inch wheel design (21-inch rims are optional), plus six little point light LEDs in the lower front bumper and the special 'Kings Red' paint option from the Golf GTI. It's even harder to tell this GTX model apart from other ID.4s inside, though there's GTX branding on the seats and if you're determined to set this version apart, you can specify a blue dashboard insert with red stitching.

Otherwise, it's the usual now-updated ID.4 cabin set-up, with a 12.9-inch central screen featuring simpler menus, a more intuitive control structure and a more responsive IDA voice assistant.

This offers fresh functions, including cloud-based weather information and the status of sporting events or stock market prices.

As part of this update, Volkswagen has (at last) illuminated the cabin temperature control sliders.

Plus the driving mode selector has been moved to the steering column and the optional augmented reality head-up display system has been enhanced.

You still have to put up with a very small (5.3-inch) instrument display. Overall, build quality is generally good but cheaper plastics still betray the cost cutting necessary to undergird all that sophisticated EV technology.

As previously, the interior design has an airy but minimalist and rather clinical feel which Volkswagen has tried unsuccessfully to lift by imprinting 'Play' and 'Pause' symbols on the two footwell pedals.and a digital instrument cluster.

At the back, there's comfortable space for a couple of adults (it'd be a squash for three).

And there's a very decently-sized 543-litre boot, extendable to 1,575-litres with the rear seat folded.

A tonne of weight can be towed too.

ID.4 GTX pricing starts from around £52,000 for the single 'Edition' model.

You'll need a bit more if, like many GTX customers, you want to pay extra for 'DCC' 'Dynamic Chassis Control' adaptive damping.

To give you some range perspective, mainstream ID.4 pricing starts from just around £40,000.

If you want the more coupe-like ID.5 GTX model, you'll need around £1,500 more than is required for this ID.4 GTX. Equipment features in the entry-level GTX run to 20-inch 'Ystad' alloy wheels, black roof rails, matrix LED headlights, LED rear tail lamps with dynamic turn signals, a panoramic glass roof, auto headlamps and wipers, front and rear parking sensors and keyless entry.

Drive stuff includes sports suspension, an augmented reality head-up display, adaptive cruise control, selectable driving modes, an exterior sound actuator and more direct 'Progressive' steering. Inside, the seats have GTX branding and there's a leather-wrapped heated multi-function steering wheel with touch control.

You also get an auto-dimming rear view mirror, a heated climate windscreen, heated front seats, 3-zone 'Air Care Climatronic' air-conditioning with controls for rear occupants, a rear view camera and interior ambient lighting with 30 colour options.

Infotainment's taken care of by a 12-inch 'Discover Max' navigation infotainment display with an upgraded 'dynaudio' stereo system.

Plus there's a wireless smartphone charger, 'Car-2-X' intelligent vehicle networking and, for semi-autonomous highway driving, Volkswagen's 'Travel Assist' traffic jam assist and emergency assist system.

Safety features include the usual autonomous braking 'Front Assist' set-up, plus 'Lane Assist', 'Dynamic Road Sign Display' and a 'Driver Alert' fatigue detection system.

We gave you the driving range figure earlier - 317 miles.

For this car's 77kWh battery, Volkswagen has now increased DC harging speed to 175kW, equipping owners for the new generation of public rapid chargers that can't come soon enough for our market, updating a UK charging network that one Mercedes executive recently dismissed as 'a cowboy outfit', something you'll identify with if you live outside this country's major population centres. Volkswagen has done its best to help by providing its EV owners with a 'We Charge' app that helps you find and use over 150,000 public charge points.

At a DC3 100kW charge point, it'll take no more than around 30 minutes to recharge your ID.4 GTX with enough direct current to cover the next 137 miles.

Using a 50kW DC charger, it'll take about an hour and a half to get an 80% fill.

Back at home, an AC1-phase 7.4kW garage wallbox would replenish this 77kWh model from zero in about twelve hours, though you can almost halve that time if your property - or business - can support an gutsier AC3 11kW charger.

At the other extreme, think in terms of needing to double the 7.4kW garage wallbox charging times we've just quoted if you merely connect to a conventional 3-pin domestic plug.

Insurance is group 34E.

If anyone was going to make an all-electric 'GTI'-style EV work, you'd put money on Volkswagen to do it.

Maybe it still will.

For now though, this doesn't feel like a car with any sort of GTI bloodline.

That doesn't mean you might not still want one of course.

If the current zeitgeist (or more likely your company fleet policy) has dictated to you that you have to have an EV, it has to be a hatch this size and it needs to be properly sporty, there's quite a bit to like about the ID.4 GTX, especially in this improved form.

Though we'd find it difficult to ignore the fact that much the same money would get you similar sportiness in a more premium-feeling dual motor Polestar 2 - or longer range in an equivalent Tesla Model 3 Performance. Neither of these cars though, nail the visual hot hatch vibe quite as well as the ID.4 GTX.

In its dynamic aspirations, it's hobbled by the massive kerb weight that is currently common amongst EVs, but it does feel usefully more engaging to drive than the standard model.

Which means that folk planning to spend big on an ordinary ID.4 (or ID.5) should consider a GTX.

Otherwise though, we'd counsel you to think carefully.

As Volkswagen should be doing in deciding how to develop the GTX brand from here.

It'll be interesting to see how they do it.
