Hyundai Ioniq, Volkswagen E-Golf, BMW i3 vs Nissan Leaf - electric vehicle group test

Before we set off, time for a quick poke around our newbie: the Hyundai Ioniq. The Leaf, i3 and e-Volkswagen Golf are well known to us, all having been the subject of Autocar road tests over the past few years and all serving customers looking for slightly different things from their first EV. And rather than competing for exactly the same customers as any of its new-found rivals, the Ioniq definitely adds to the breadth of choice in the market.

It’s big, the Ioniq: 50mm longer at the kerb than the Leaf and almost 250mm longer than the e-Golf. Building it on Hyundai’s first-ever platform to be dedicated to EVs and hybrids has paid dividends, and if you need space to carry adults in the back seats as well as a large boot in your new EV, you need look no further. I’m not sure how many customers really need such things from a second car, nor how many would be ready to switch to electric power for their only car. My guess is that it’s not many. Still, plenty of cleverly packaged space isn’t to be sniffed at.

But Hyundai has brought the Ioniq into the segment in a competitive place on more than just boot space. Even in range-topping form, the car is lighter than both the Leaf and e-Golf, beats both on official claims for battery range and 0-62mph acceleration and is cheaper than both at like-for-like list price (discounting the smaller-batteried version of the Nissan).

But it’s the BMW i3 that continues to stand apart from the batterypowered hatchback set on the specification sheet. Carbonfibre and composite construction (and downsized proportions) make the German 150kg lighter than the next lightest car here. A 168bhp motor gives it an average three-second advantage on 0-62mph sprinting. A 33kWh drive battery, upgraded as part of a facelift earlier this year, is bigger than any its rivals offer.

And all that, with such imaginative design and a premium brand badge on the bonnet, comes at a pleasingly competitive price. Unless the admittedly limited practicality of its relatively small rear cabin and boot is a barrier to the use you have in mind, the BMW plainly deserves your first test drive – although, for reasons that will become apparent, we’d actually advise making it your second.

In which vein, off we go into the melee of north London in the gathering afternoon rush: the Great North Way, The North Circular, Archway Road, Holloway Road, Finsbury Park. Buses, lorries, vans, cabs and motorcyclists all battle to be first away from the traffic lights, then jostle for position at the next. Lanes appear then disappear, only to reappear as bus lanes or feeder lanes that you really don’t want to be in. Roadworks create bottlenecks that queue traffic back for miles and diversions force you to change tack away from your regular route.

Cyclists and moped riders mock your hustle-and-crawl progress, dodging forwards through less available road space than you’d be comfortable walking in. Here you need to be in a comfortable, intuitive driving environment that soothes the chaos and eases your onward passage, not one that makes a tough situation worse.

Could the Ioniq’s do that? Possibly. The Hyundai’s instrumentation is clear, its driving position and seat are both good, its navigation system is okay and its visibility is reasonable. But the e-Golf’s are all better. The e-Golf plays it safe; it doesn’t reinvent the wheel, or the gear selector, if it needn’t, so every control instantly feels familiar. The e-Golf’s more compact proportions make it an easier car to thread through gaps than the Ioniq. Its more sophisticated, detailed and intuitive navigation system helps put you at ease when you’re forced off-route. Its higher perceived quality levels make it a more pleasant place to be. 

My first surprise of the day is discovered in the Leaf. Its interior suddenly and unmistakably feels antiquated – and a little bit cheap. The plastics in here aren’t a patch on either the Volkswagen’s or the Hyundai’s, and neither is the infotainment system, which is tricky to navigate and looks blocky and backward by comparison. It’s not a small car, the Leaf, and yet it’s not desperately spacious. The front seats are high-mounted and flat-cushioned, while the steering wheel is quite steeply raked, like a bus wheel. Is the Leaf making all  this hustle and bustle easier? I’m not so sure.

But a bigger surprise awaits in the i3 – a car quite unlike any other hatchback. You sit high in the BMW, swinging your legs in over a raised carbonfibre sill – but then adopting a relatively recumbent pose at the wheel. In front of you is a large windscreen and a low fascia slimmed down as if to visually prioritise the two focal points that actually matter: the simplified, downsized instrument screen and a widescreen infotainment display big enough and crisp enough to knock everything else here for six.

It’s a tall, narrow, square sort of car, the i3 – great to see out of, easy to judge width-wise and with supershort overhangs. So if you weren’t already falling for the BMW as you opened its frameless coach doors and began admiring its fascinating materials, chances are you probably will be as you realise how peculiarly suited it is to city roads.

So what else matters? A responsive powertrain, good directional agility, good ride compliance and progressive, predictable controls: these are the four dynamic traits a really good town car needs, I reckon. Being electric, all four cars tick the first box, but from there on we can whittle things down a bit.

Neither the Leaf nor the Ioniq feels desperately agile, the former because it’s softly sprung and rolls quite hard, the latter because of its heavy steering and long wheelbase. The e-Golf rides best, quietly and with suppleness, followed by the Leaf and the Ioniq, and finally by the i3, which is firmly sprung and a bit brittle-riding but twice as agile as anything else here. The most consistent, pleasant and intuitive controls belong to the e-Golf, the least so to the Ioniq, whose brake pedal tuning is as unflattering as its steering.

But where the controllability of these cars really matters is when it makes them better-functioning EVs. Both the Ioniq and e-Golf are commendable for having switchable battery regeneration settings; you can allow them to coast when the road opens up in order to save power (and, having so little rolling resistance, EVs really do coast) and then blend the regen back in to slow the car without needing to go near the brake pedal. Neither the Leaf nor the i3 really allows you to do that as effectively.

At the other end of the spectrum is the Nio EP9 electric hypercar

The i3 counters with an always-on regenerative setting that’s at least twice as strong as any of the other cars here, and that takes some getting used to. It’s about the only production car I’ve ever driven on which a brake pedal could be an optional extra. But then so much about the i3 takes some getting used to – and when you are used to it, I bet you none of the other cars here could persuade you out of it.

The truth is that both the e-Golf and the i3 are quite plainly a cut above most of the standards set by the Leaf and Ioniq – and either of them could be our winner. The e-Golf is the battery car done brilliantly, in order to be spectacularly familiar, comforting and ordinary, but the i3 is even more brilliant and even more extraordinary in every way.

It’s the VW that takes the pain out of the urban grind best – and that was the car we set out to identify. But the BMW simply transforms it – goes above and beyond what you expect from an electric hatchback and succeeds in being fast, energy efficient (see our urban test efficiency figures for the proof), fit for purpose and fun to drive.

Is the electric car revolution finally here? Read our thoughts

The i3 is not just an EV: it’s the automotive urbanite right-sized, rethought and reinvented for a century in which an electric motor is simply the best technology for the job. The i3 is a car you can not only enjoy but also have real affection for. And given the obvious limitations of electric technology and the inevitable compromises we’ll all have to accept by adopting it at least for now, affection ought take EVs further than almost anything else.

Charge wars: who's winning the infrastructure race?

Zap-map.com is a website you’ll need bookmarked in your smartphone browser if you’re to make a success of EV ownership. The site records the location of every public charging station in the UK and categorises them to allow you to search only for the particular kind that’ll get you to your meeting 150 miles away, or get you home again after an unexpected diversion.

A rapid charger is the type likeliest to do those things — but, scandalously, the emerging EV market has been allowed to diverge on different hardware standards. The Nissan Leaf and Mitsubishi i-MiEV came along first and adopted a 110V DC system called ChaDeMo, which the Kia Soul EV also uses. But some of Europe’s EV makers have since adopted another 110V DC system, called CCS (used by the BMW i3 and Volkswagen e-Golf and Volkswagen e-up), while others (such as Renault) prefer an AC rapid charge solution.

For those who only want life to be made simple for early adopters, the situation is deplorable. But the good news is that, after a slow start, the number of CCS chargers in the UK has now increased to a level at which all EVs are almost equally usable. If you want the best-supported EV and the easiest ownership experience, that remains the Leaf — but the difference is now small enough that it wouldn’t prevent us from recommending rivals.
