BMW 218i vs BMW 420i

What's the difference?

The badge might say one thing, but the 2 Series Gran Coupe sticks to the time-honoured template of being a compact yet comparatively practical three-box, four-door sedan, complete with a big boot.

More importantly, it drives and behaves like a BMW – which means sufficient-to-strident performance depending on grade, athletic dynamics and pleasing refinement on one hand, as well as a stiff price and a hard ride on the other.

A true BMW in name and nature, then..

The BMW 420i is a terrific car if you're after a bit of style and sophistication. Not everyone will warm to your car's nose, but if you get it de-chromed, like this white one, it really does look pretty good. It's a car that uses very little fuel, moves along smartly and is brimming with a decent amount of tech, even if it could do with a bit more safety gear at this price. 

I reckon this car is settling well into the automotive landscape and ignoring it because of a few loudmouths think the grille is too big would be a terrible waste.

BMW is calling the F74 a new-generation 2 Series Gran Coupe, and there have been obvious and even profound changes throughout and underneath, including to some of the sheetmetal.

But this is not an all-new car by any stretch, with the glasshouse, doors and roof amongst many other body items carrying over from the F44.

That now remarkably Kia Cerato-esque nose ushers in new LED lighting motifs and an updated kidney grille, but whether they sit easily with the rest of the car is debatable. Redesigned tail-lights, different colours and new alloys make up the majority of the exterior changes.

Betraying the latest 2 Series Gran Coupe’s newness claims are near-identical dimensions, with that redesigned front end and bumpers contributing to a 20mm increase in the F74’s 4546mm length, while revised suspension and damper settings help account for the 25mm boost in height (to 1445mm). The BMW’s 1800mm width and 2670mm wheelbase remain the same.

There’s a higher level of newness to be found inside.

The internet exploded when it became clear the big kidney grille was for real. To be fair, BMW did itself absolutely no favours by ensuring the photos of the 4 Series made the twin grille look Easter Island statue sized. 

And it persisted in doing them naked, without number plates to break up the look. In the flesh, it all works, the nose is striking but not completely overblown. 

BMW coupe elegance reigns supreme in profile, however, with excellent proportions, and even in base form the wheels are the right size. The slim tail-lights and sculpted tail complete the look. It's a car I think most people love looking at. Hardly anyone mentioned the grille.

The cabin is excellent, as are all of the newer BMW interiors. It's not really a base model, given the price, but the mix of Alcantara and synthetic leather is very pleasing. 

The big screens for the media and instruments headline the cabin with high-tech style and while it's not avant-garde, it's sharp and feels premium, which is just as well.

During the media presentation at its launch, BMW described the 2 Series Gran Coupe as being almost as large as a 1990s E46 3 Series, and it is in all major dimensions except wheelbase.

Plus, being a front-drive-biased/transverse engine proposition instead of rear-wheel drive should make it roomier than the F74’s iconic ancestor.

The sense getting in is that this is certainly not too low or cramped as per a more-traditional coupe, with plenty of space for legs and shoulders, while even the optional sunroof fitted to our 218 left us with headroom to spare.

The redesigned dash is a visual and operational treat, with crisp, clear instruments, a logically presented and intuitive centre display screen offering fast and easy operation, excellent ventilation and ample storage. Full marks here.

Better still, attaining the perfect driving position is possible for most people, on brilliantly supportive front seats. This is the stuff BMW does right.

Improvement suggestions for the next update? Some people may complain about the somewhat less-than-premium feel of some of the lower-lying plastic trim; not everybody will love the swatches of colour stitching (we love it); why does the steering wheel have to be so wide-of-rim? Side and rear vision is restricted by fat pillars, rising shoulder lines and a shallow rear window; and there is quite a bit of road noise that enters the cabin at speed.

Still, even the back seat is sufficiently spacious for most users, with the sole exception of taller folk having to negotiate a sloping rear roofline. If you’re below 180cm, this should be fine. Most amenities minus overhead grab handles are also fitted.

Further back, the boot is surprisingly accommodating, with 430 litres of cargo capacity that’s enhanced by a 40:20:40 split-fold backrest, and the aperture should be big enough for bulkier loads, but the lack of a spare wheel will be bad news for many buyers. The supplied tyre-repair kit is just not good enough.

But, you know what is good enough? The engines BMW builds, that’s what.

As a sports coupe, it's hardly a practical all-rounder but it's not a squishy 2+2 either. The rear seats are sculpted for maximum headroom and have the added bonus of holding onto rear passengers. 

Six footers won't be super-comfortable but it's bearable for short trips. There are two ISOFIX points back there, too. 

The front seats electrically fold out of the way for ingress and egress, but it's not an elegant process.

Front-seat passengers score two cupholders and bottle holders in the doors and a black hole for your phone and its wireless charging pad.

The boot takes an impressive 440 litres and the rear seats split and fold like good little soldiers.

The 420i starts at $71,900. That's a fair bit of money, I think you'll agree.

You get 19-inch wheels, a 10-speaker stereo, LED headlights with auto high beam, head-up display, power front seats, lighting package, auto-parking with reverse assistant, synthetic leather and Alcantara interior, 'Live Cockpit Professional' (fully digital dash), wireless phone charging and digital radio.

The massive 10.25-inch touchscreen may be smaller than the 12.3-inch digital dashboard, but it still looks huge. BMW's Operating System 7.0. is a cracking set-up, and you can control it via either touch or the 'iDrive' rotary dial on the console. It also has Apple CarPlay and Android Auto. Both of them, wireless. You don't read that every day.

You also get 'BMW ConnectedDrive', with some remote services that last for three years. The subscription includes things like the endearingly weird 'Caring Car' and the far less weird real-time traffic information.

The 4 Series is available in eight colours. 'Alpine White' is the only freebie while 'Black Sapphire', 'Arctic Race Blue', 'Portimao Blue', 'San Remo Green' and 'Mineral White' are $1538 each (or part of the 'Visibility Package'). 'Tanzanite Blue' and 'Dravit Grey' are a hefty $2962.

My car for the week had the $6300 Visibility Package (metallic paintwork, sunroof, BMW Laserlight, Ambient Light, which is worth it for the amazing Laserlights alone), the $2860 'Comfort Package' (lumbar support, electric boot, heated front seats, 'Comfort Access' with 'BMW Digital Key') and an $800 black pack. All this took the price to $81,860.

Three F74 powertrain choices are available for Australia in 2025. And none even remotely reflect what their respective badges imply on the boot.

The 218, for instance, is not powered by a 1.8-litre engine, but BMW’s long-lived B38 1.5-litre three-cylinder turbo petrol unit. Making 115kW of power at 6500rpm and 230Nm of torque between 1500rpm and 4600rpm, drive is channelled to the front wheels via a seven-speed dual-clutch transmission (7DCT).

With a kerb weight of 1420kg, the 218 has a power-to-weight ratio of 81kW per tonne, helping it achieve the 0-100km/h sprint time of 8.6 seconds, on the way to a 230km/h top speed.

Not enough? The 220 features the ubiquitous B48 2.0-litre (not a 2.2-litre) four-cylinder turbo petrol engine/7DCT combo, pumping out 150kW at 6500rpm and 300Nm from 1450-4500rpm. Tipping the scales at 1525kg for 98.4kW/tonne, its 0-100km/h time is 7.3s and top speed is 250km/h.

Want more? Stretching to the M235 xDrive sadly doesn’t mean a 3.5-litre in-line six, but a modified B48 2.0L/7DCT duo, delivering 233kW at 6500rpm and 400Nm from 2000-4500rpm to all four wheels. Result? Weighing just 50kg more than the 220, it boasts a heady 148kW/tonne, for a 0-100km/h of just 4.9s and a 250km/h v-max.

As with all of the UKL2/FAAR transverse-engine front-to-AWD platform models from non-electric Minis through to sub-X3/3 Series BMWs, you’ll find MacPherson-style struts up front and a multi-link independent rear end out back.

If you’re reading this outside of Australia, you may notice that none of the current F74 models offer mild-hybrid tech, in contrast to their European counterparts. And don’t go expecting any manual gearboxes either, unfortunately.

The 420i’s 2.0-litre turbocharged four-cylinder, codenamed B48, spins up 135kW/300Nm. Driving the rear wheels through an eight-speed ZF automatic transmission, you'll go from zip to the 100km/h mark in 7.5 seconds, which is brisk, if not staggering.

OK, so is the 2 Series Gran Coupe cheap to run?

BMW reckons the 218 and 220 will average 6.3 and 6.7 litres per 100km, which means combined average carbon dioxide emissions ratings of 143 and 152 grams/km respectively.

Filling the 49L fuel tank with 95 RON premium unleaded, that translates to around 775km in the 218, and 730km in the 220 between refills.

Predictably, the M235 xDrive uses more, at 7.7L/100km for a CO2 rating of 176g/km. That’s a distance of about 635km.

Over our launch run, which took us from Sydney’s Circular Quay to Wollongong, the 218’s trip meter was reading in the high 8s and about 10 for the M235.

BMW's official combined-cycle figures seem to be slowly moving towards reality. The 420i's sticker figure of 6.4L/100km was met with an indicated 6.8L/100km, which was excellent going for almost exclusively suburban and urban running. 

It's a solid result, but being a BMW, it's premium unleaded only for its 59-litre tank.

With my generally unsympathetic (but not psychopathic) right foot, that means a real-world range of over 800km between fills.

Earlier, we mentioned that the 2 Series Gran Coupe is way more expensive than fine alternative sedans like the Mazda3 and Toyota Corolla.

And while that still stands, there is a remarkable solidity and refinement difference between those and the BMW that helps justify the premium. And nowhere is this more evident than from behind the wheel.

Sat on body-hugging seats and clutching that (too chunky) steering wheel, there is a sense of sporty occasion, backed up by quality trim and an aroma of expensiveness.

For a turbo three-cylinder car weighing 1.5 tonnes, the 218 does a lot with a little, offering spirited off-the-line acceleration and pleasingly lag-free throttle responses at lower speeds. You’d never call it fast, but it is a quick point-to-point urban mover. Only the unavoidable three-pot thrum lets you know you’re in the lowest mechanical spec. And, also, the delay at freeway speeds in building momentum when overtaking.

Which is why, for less than five per cent extra, the 220 with the 2.0-litre four-cylinder turbo would probably make a better buy. Sadly, that isn’t on sale yet in Australia, so we missed out on driving it during the Sydney launch. But in the scores of other BMWs and Minis we’ve tested this in, it’s a cracking little powertrain.

Whether the big leap (nearly $25K worth) to the M235 is worth it depends on how fast you drive and how much you value/need AWD. This is a terrifically muscular machine, since it provides rapid performance via a tidal wave of power, even with the lightest flex of your right foot. On-point and on-brand, this fun and fiery flagship possesses the grand-touring spirit that the rakish design and tech-heavy engineering promise.

To that end, in both the 218 and M235, the steering makes the driver feel connected to the car, resulting in precise and controlled handling. The driver-assist safety tech is beautifully calibrated and nuanced in its intervention, and the brakes are second-to-none.

What is also on-topic for a BMW is the firm suspension, despite the adaptive dampers fitted as standard equipment.

It isn’t stiff or overly uncomfortable, but bumps are certainly always felt, and they’re accompanied by fairly constant road-noise drone over some surfaces.

As such, you’re constantly reminded that dynamic athleticism is the priority here, rather than sumptuous comfort. We’ve experienced much worse from BMW, but a magic-carpet ride isn’t what’s in store for the 2 Series Gran Coupe owner.

So, what’s our verdict then? The 218 is a rorty little tryer that never fails to involve the driver, while the M235 ushers in an elevated level of acceleration, grunt and grip. We suspect that the 220 will be the Goldilocks-zone happy medium.

For (largely) better as well as for (occasionally) worse, these drive and feel like a BMW should.

One of the main things that sets a BMW sedan or sedan-based coupe apart is that they're good everywhere, except perhaps in quicksand. 

As the platform has matured and BMW's persistence with run-flat tyres has yielded improvements in tyre construction, the 3/4 Series platform (and many others - the internal name for the platform is CLAR) has once again become the benchmark for ride and handling.

For some people reading this, that's a lot of blah blah blah but the main point is, it's a terrific thing to drive whether you're dawdling along in traffic, dealing with traffic calming or bombing down your favourite deserted road.

The Bridgestone tyres on the 420i aren't as ultimately grippy and sticky as the alternative rubber on the 430i but they work well in town and are quiet on the 80km/h roads so prevalent in Sydney. 

The steering is absolutely lovely, providing just the right weight at any given speed and throwing in the road feel to inspire confidence.

Ride around town is compliant but with the whiff of fun if you decide to push things outside of the city. 

Its capabilities are still more than worthwhile day-to-day, however, because the way it handles the need to duck in and out of spaces in traffic is extremely handy.

The 2.0-litre four-cylinder is as smooth as rival Audi's. It doesn't sound like much (with a few vestigial pops in Sport mode) but it's certainly got the power to get you out of sticky situations and a transmission that's willing to play ball, whether in Sport or Normal.

Without the adaptive suspension of its 430i and M 440i brethren, this is a very smooth, easygoing sports coupe, with just enough sportiness to keep you interested, if you're that way inclined.

The 4 Series comes with six airbags, ABS, stability and traction controls, forward AEB, forward collision warning, lane-departure warning, reverse cross-traffic alert and reversing camera.

The 4 Series hasn't been tested by ANCAP or Euro NCAP and the 3's five-star rating can only be a guide because of the very different structure of the 4. 

Sports cars rarely fare well in the sometimes complex rules so carmakers tend to keep them away from the clutches of crash testers.

Here, however, is where BMW can do a bit better.

While the five-year/unlimited-kilometre warranty is where most premium brands are, it falls short of several Asian alternatives. Roadside assistance is for just three years and there is no capped-price servicing.

Service scheduling is also condition-based, meaning the vehicle will alert the driver when a service is imminent. This may not suit everybody, and we always recommend at least every 12 months or 10,000km, just to be on the safe side.

BMW does offer pre-paid service packs that take in basic maintenance for the first five years at $2369 or $3782, including brake-pad replacement, which works out to be about $475 and nearly $760 annually respectively. There is also a cap on mileage during that time frame: 80,000km.

BMW offers a ho-hum length of three years and 100,000km of warranty coverage. Mercedes has gone to five years so one wonders why BMW (and Audi) hasn't joined its German rival.

Servicing is entirely reasonable at $1650 for a five-year/80,000km package that covers the 12 month/16,000km servicing regime. 

At $330 per service, it includes things many carmakers don't, such as brake fluid and spark plugs. 

You can go full noise with the 'Plus Package', which costs $4500 and chucks in brake pads, rotors and even windscreen-wiper replacement. That doesn't seem like terribly good value to me unless you drive like a lunatic.
