Is the Tesla Model 3 the game-changing EV that spells the beginning of the end for cars like the BMW 3 Series? Matt Saunders referees the battle of the 3s
A simple question deserves a simple answer – but don’t expect one here. This question was asked on social media by Matt Miller in response to news that we were heading to Amsterdam for our first European test drive of the Tesla Model 3. “Interested to see how you think it compares to the standard, uppity sports sedans. Would you own a Tesla Model 3 over an Audi A4 or BMW 3 Series?”
Well, would we? After the big build-up, is this the car that could finally make the electric vehicle usable, affordable, practical and viable for people not as a replacement for a city-hopper or school-run supermini or a family’s second car, but in place of a proper, good-sized, fairly high-mileage executive saloon?
We had 36 hours, last week, to begin finding some answers, with the keys to a range-topping Model 3 Performance in one hand and those for a brand-new BMW 330i M Sport in the other. We knew before we started, of course, that this would be only the beginning of a long process, and a critical year, in establishing exactly what the state of the zero-emissions passenger car art currently is. Of establishing, too, exactly how much the Model 3 moves the game on; and whether it’s quite the transformative car that Tesla’s ever-zealous supporters so desperately hope it’ll be.
The BMW plainly handles better but perhaps not by as much as you might expect
An imperfect start, you might even say. You wouldn’t chose to line this particular Model 3 up against this 3 Series if you had the pick of both full model lines, after all.
The Model 3 Performance is one of only two versions of the car that are now on sale in mainland Europe and will come to UK buyers later this year. It has twin electric motors; 444bhp of peak power; and 471lb ft of torque from zero rpm; and it is good for 62mph from rest in what, I assure you, is a 3.4sec dash that gives new meaning to the word ‘startling’. It’s also likely to cost UK buyers in excess of £60,000 at list price. Cue a swift intake of breath.
The 330i M Sport looks, in some ways, like half the car on paper, with its 255bhp, 5.8sec 0-62mph claim and narrowly sub-£40k asking price – but, for the moment, it’s the most powerful petrol-powered car in the G20-generation 3 Series model range. It’s also a car you can refuel within minutes, almost anywhere you happen to want to stop, and it will cruise for a good 400 miles between fills. It’s a car you can drive from Farnborough to Amsterdam in a day, without stopping for any longer than is needed to pump 60 litres of unleaded, plus a litre or so of bodily fluid. It will do much less for your Costa coffee reward points balance than the typical modern EV. Something tells me we will not escape the influence of these factors over the next few pages.
But what we must acknowledge is that the plug-in hybrid 330e, which might be considered the Model 3’s closest competitor and is due on sale later this year, won’t be unlike the 330i to drive. It, too, has a four-cylinder turbo petrol engine and a very similar performance level. Meanwhile, Tesla’s single-motor, rear-wheel-drive Model 3 Long Range, which ought to enter the UK model range at just beyond the £40,000 mark, should be similar to the Performance to use and drive. Like the mid-range Model 3 we’d have preferred to match it up against, the Performance has a 75kWh drive battery and a usable range estimated at more than 300 miles. So, no, we haven’t quite got like for like here, but we’ve certainly got close enough to make some useful initial conclusions, though.
Observations come first. If you’ve ever seen a late-model 3 Series, you know how big a Model 3 is: the two saloons are within 15mm of each other on overall length. Given that an electric powertrain is supposed to make space in a car compared with a combustion engine, then, it’s odd that the Tesla should lose the first exchange of this test, on cabin and boot space – but the
BMW offers notably more cabin room, a lower and more enveloping driving position and a considerably bigger boot.
Just-so, right-sized practicality is at the very heart of the appeal of the compact saloon car. For a few generations now, the 3 Series has come to market with enough of it for four typically sized adults to travel in comfort and the G20 3 Series hits that sweet spot even with a little bit of space to spare.
The pure, seamless thrust seems ridiculous even for an EV
The Model 3, however, makes adults feel squeezed in its second row. The Tesla’s packaging leaves little foot space under the front seats, makes head room slightly tight underneath that full-length glass roof and obliges you to sit bandy-kneed if you’re behind a full-sized adult. The BMW is guilty of none of these offences. It also has a wider, deeper boot than the Tesla’s so it would be more useful for carrying bulky items, something the American’s separate front cargo compartment wouldn’t compensate for.
The Tesla’s driving environment certainly feels like it should belong to the more spacious car of the two. The Model 3 makes a good first impression on perceived quality and its pared-down, minimalist fascia is tidy, clean-looking, modern and very pleasant, not unlike your own personal branch of the Apple Store. Big windows and a glass roof make for a light, airy feel, although the business of actually interacting with the car is something that may be slightly unintuitive, given that almost every secondary system and function is managed through the car’s monolithic 15in touchscreen computer display.
The 3 Series’ cabin, by contrast, isn’t one needing several hours and repeat dealership visits to become familiar. It neatly reminds you that the best-laid-out car interiors look busier than designer apartments because they need to be that way in order to work well on the road.
Electric cars have had plenty of prominence on the pages of this magazine over the past decade. You’ll have read about how uncanny they can feel to drive: super-responsive, eerily quiet, torquey at low speeds. But when you actually compare a Model 3 with a 330i back to back, you become aware that your isolated perceptions are to be trusted in some cases – and yet in others they are surprising misleading.
There is certainly no keeping up with an energetically driven Model 3 Performance around the stop-and-start streets of a major European city like Amsterdam; not in a 3 Series, at any rate. A superbike might manage it; a catapult, too, until such time as you needed to change direction.
The pure, seamless thrust generated by the Tesla’s motors, from the instant your right foot begins to move the accelerator pedal, seems ridiculous even for an EV. The car has two drive modes – Sport and Chill (thanks for that one, Instagram generation) – and if you use Sport, you’d better have decent fine motor control in your right ankle.
Yeesh, it’s responsive. You might even say too responsive, since the force you can inadvertently unleash with a half inch too much pedal can make you look pretty juvenile. There is, needless to say, barely the blink of an eye’s delay between asking for, say, 50% of the car’s available torque and getting it. By my rough estimate, though, you probably only need to use the first 25% of the throttle travel to get that 50% engine torque because of the aggressive calibration of the car’s right-hand pedal. Suffice it to say, I think I’d be a ‘chilled’ sort of Model 3 owner.
By contrast, when you’re in the 330i sat at a traffic light that has just turned green, you need to wait for several things to happen before a meaningful amount of torque makes its way to the car’s driven wheels. As you lift off the brake pedal, the engine first has to restart; and then the crankshaft needs to spin up; and then the gearbox has to lock up; and then the turbo needs to spool up; and finally the force you requested three or four seconds earlier is transmitted to the road. That’s the biggest difference of them all between driving an EV and almost any modern combustion-engined car: a heartbeat versus three or four seconds – and not quite every time you accelerate, but often.
Now let’s move our frame of reference out of town. With direct drive gearing, the Model 3’s electric motors feel like they’re dropping away from peak torque beyond 50mph, when the 330i is just getting into its stride. At that point, if the EV holds an outright performance advantage, it’s mostly to do with pedal response, because full power feels pretty similar in both cars
when it arrives.
On the motorway, meanwhile, it’s actually the 330i that’s the quieter and more refined car. Sure, the Tesla’s powertrain is the quieter but the BMW’s better cabin sealing more than makes up for the deficit. Wind noise intrusion in the Model 3, with its frameless doors and huge glazed expanses, is a bit of a vulnerability. It wouldn’t really bother you on a longer trip, but you’d notice it all right.
Does the BMW handle better? Plainly so, but perhaps not by as much as you might expect, given its 300kg kerb weight advantage, which is a compliment to Tesla’s vehicle dynamicists. The 330i has a remarkably level of poise both when cornering and over bumps. It steers less directly than the Model 3 at first, but with greater linearity and mid-corner bite. It feels more neutral and engaging when accelerating out of a bend and more precise and communicative in its handling at all times.
The Model 3 rolls only a little more but makes you feel every degree in your more lofty driving position and it also has more to do to rein in its body movements. It rides comfortably but ultimately the BMW is the more satisfying driver’s car by a decisive margin, although you probably do need to get out of town to appreciate it.
Would any of that actually matter to a buyer, though? That’s what you find yourself puzzling when summing up what really separates these cars and seeking to pick a winner. To some, the Tesla’s electric motors and zero tailpipe emissions will be like a 50-yard head start in a 100-yard running race; from where, by the way, it’s more than good enough to sprint home in the lead.
For others, the allowances and limitations necessarily associated with running an EV in daily use – and they’re still significant here, although they’re set to become less and less so (see p49) – would rule it way out of contention. Because it depends so much on personal circumstance, nobody can tell you which side of that equation you’re on. You have to work it out for yourself.
I can help a bit, perhaps. Over plenty of different test routes and driving styles and a good seven or eight hours of driving altogether, the energy efficiency of the Model 3 Performance averaged out at 2.8 miles per kWh: enough for 210 miles of usable range on a charge of its 75kWh battery. Drive exclusively for economy, at reduced pace, and you can just about put 300 miles between charges, but that means keeping the average speed below 50mph. We should point out, for the sake of balance, that this was from the Performance model on 20in rims and performance tyres, and Tesla’s Long Range derivatives might add 10-20% to that range, on the basis of relative US-market claims.
Still, there are significantly cheaper EVs that go quite a bit further on a charge; and on that basis, even though the Tesla’s recharging network is now better, and improving faster, than ever before, it’d seem unjust to declare this the car to finally convince the majority that an EV could be as viable, usable and practical as one of the best, most broadly talented combustion-engined cars in the world.
So no, Mr Miller, now is probably not quite the time for the average 3 Series owner to switch from BMW to Tesla. The simplest answer to your question would simply be to point out that it’s the job of the latest technology to make for a better car and, in the Model 3 at least, electric car technology hasn’t quite done that yet. Not in enough ways, at least.
The time might well come soon, though; within the life cycle of these particular cars, considering the way that CO2 legislation is
going. And I dare say many of those whose usage pattern would accommodate the switch already probably wouldn’t look back. A
TESLA’S CHARGING PICTURE IS CHANGING
Tesla’s first European Supercharger location opened in Norway in 2013. Last year, it opened its 400th – and more than 50 of those are in the UK, with room between them to charge more than 300 cars at a time.
At most of Tesla’s Supercharger sites, a 75kWh Model 3 could be restored from flat to an 80% charge in less than an hour, good for more than 160 miles of range even at our ‘average’ estimates. A full charge would take 90 minutes.
However, the Model 3 is the first Tesla capable of a rapid charge in other locations as well as at the firm’s proprietary Supercharger sites. European-market cars are fitted as standard with CCS-Combo rapid-charge ports and can therefore rapid charge at hundreds more locations around the UK than existing Model S and Model X cars. Most UK motorway services’ rapid chargers are still limited to a 50kW charging rate, compared with Tesla’s own 120kW Supercharger standard, but some are being upgraded to as much as 150kW.
But even better is yet to come for Model 3 owners. Earlier this month, Tesla announced that it would begin an upgrade programme for its global Supercharger sites to V3 specification, which is expected to cut vehicle charging times by half as peak per-car charging rates increase to 250kW. That’s a full charge for all but the most empty, bigger-capacity cars in less than 30 minutes. The first V3 Superchargers are expected in Europe by the end of 2019.
