BMW 220i vs BMW 420i

What's the difference?

The BMW 2 Series coupes and convertibles combine understated good looks with great dynamics and top-shelf quality. Extra equipment, especially the iDrive6 multimedia system, has brought it up to speed in terms of tech and value, while the M240i sets the compact performance benchmark. And if you really want to push the envelope, the M2 is right there at the top of the under $100k performance pyramid.

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.

The biggest visual clue to the revised 2 Series is the circular design bi-LED headlights, now standard on the 2 Series entry 220i, and mid-range 230i models, while hexagonal adaptive LEDs are standard on the top-shelf M240i.

But BMW couldn't leave those little light-emitting diodes alone, with LED front fog lights joining one-piece L-shaped LED tail-lights across the range.

Luxury Line-equipped cars feature a subtly revised nose treatment with larger intakes and a reshaped 'kidney' grille. There are also four new alloy wheel designs – a 17-inch alloy fitted standard to the 220i Luxury Line, and three optional M alloys for M Sport models (all no-cost options on the M240i).

The 230i M Sport features black, high-gloss bars in its kidney grille, as well as a black chrome finish for the exhaust finishers.

On the inside, there's the addition of a 'Black Panel' digital instrument cluster, which remains matt with the ignition off, and lights up with sharp graphics, configurable across conventional speed and rev readouts, as well as gear position, engine-efficiency data, vehicle settings and nav guidance.

There are also high-gloss finishes across the centre stack and front console, and even greater attention to detail around panel joins, trim stitching and switchgear.

But the hero is the latest iDrive6 multimedia system, run through an 8.8-inch colour touchscreen (6.5-inch on 220i), providing access to live content, radio and audio, navigation and maps, phone functionality, and vehicle settings through a simple and customisable app-style interface. The iPhone really as inspired car companies.

The M2 boasts M-specific instrument display content and a go-fast red needle on the tachometer.

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.

Surprisingly, at a little over 4.4 metres long, the 2 Series (Coupe) is around 10cm longer than its 1 Series hatch stablemate (M240i +15cm), but aligns with its just under 1.8m width, and 1.4m height.

It seats four, with plenty of room up front and multiple storage options, including two cupholders in the console with an oddments tray behind, a 12-volt outlet, a lidded storage box between the seats with USB connection, a reasonably sized glove box, and segmented bins in the doors big enough for large water bottles.

While it was coupes only on the launch drive, we know the convertible has a pair of cupholders in the back, but not so in the coupe, and while headroom in the soft-top is okay (especially with the roof down) it's a squeeze in the hardtop.

More a 2+2 than a full four-seater, getting into the rear is an athletic exercise, and once installed, leg and headroom for this 183cm tester is tight. That said, kids up to teenager-size would be fine.

Boot volume is 390 litres (a 3 Series Coupe is 480 litres), with run-flat tyres on the 220i and 230i meaning there's no spare (or repair kit) under the floor, but the performance-focused M240i and M2, pack a 'BMW Mobility Kit' (compressor and tyre sealant to cover minor damage) in line with their high-performance (non-run-flat rubber).

A 60/40 split-folding rear backrest liberates extra load space, and a 'Through Loading System' with luggage compartment dividing net, and 40/20/40 split-folding rear seat is optionally available (220i & M2 Pure - $350 / 230i - $385 / M240i & M2 - $500).

And if you're keen on towing the 220i can pull 680kg of unbraked trailer, and 1500kg braked, with the minimum number stepping up to 715kg for the 230i. The M240i and M2 are no-tow zones.

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.

The 220i is powered by a 2.0-litre 'TwinScroll' turbo-petrol four, featuring 'Valvetronic' variable valve control and 'Double-VANOS' variable camshaft control, and developing 135kW at 5000rpm, and 270Nm between 1350-4600rpm.

Using a retuned version of the same engine (lower compression ratio, more turbo boost), the 230i pumps out a solid 185kW at 5200rpm, and a grunty 350Nm from just 1450-4800rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only.

Then, the M240i is powered by a 3.0-litre, six-cylinder, turbo-petrol, pushing out no less than 250kW at 5500rpm, and a thumping 500Nm between 1520-4500rpm.

The same (8HP50) eight-speed auto transmission is used across the board, pushing drive to the rear wheels only, and happily, a six-speed manual gearbox is a no-cost option on the M240i.

The full-house M2's 3.0-litre turbo six produces 272kW at 6500rpm, and 465Nm from just 1400-5650rpm (500Nm from 1450-4750rpm on overboost), driving the rear wheels through a seven-speed dual-clutch auto, although a six speed-manual is a no-cost option (and standard on the M2 Pure).

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.

Claimed fuel consumption for the 220i Coupe, on the combined (ADR 81/02 - urban, extra-urban) cycle, is 5.9L/100km, emitting 135g/km of C02 in the process. The 220i Convertible rates 6.1L/100km (140g/km).

The 230i Coupe is line-ball with that at 5.9L/100km (134g/km), and the the 230i Convertible at 6.2L/100km (142g/km).

The price of performance starts to bite with the M240i consuming 7.1L/100km (163g/km) in coupe form, and 7.4L/100km (169g/km) as a convertible.

Then, as you might expect, the M2 is thirstiest of all, the dual-clutch auto consuming 7.9L/100km (185g/km), while the six-speed manual version slurps 8.5L/100km (199g/km).

Auto start-stop is standard, fuel tank capacity is 52 litres across the board, and although technically these engines can run on anything from 91-98RON unleaded, BMW recommends 95RON premium as a minimum.

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.

Four 2 Series variants were offered for the launch drive program, a 230i Coupe (which BMW nominates as the most popular model in the range), M240i Coupe, M2, and M2 Pure.

Claimed 0-100km/h acceleration of 5.6sec for the 230i M Sport Coupe is quick, with the convertible stopping the clocks three tenths later.

Peak torque of 350Nm is plenty, and with that number available from 1450-4800rpm the mid-spec 2 Series is an entertaining drive.

It's M Sport (strut front, five-link rear) suspension keeps the body well buttoned down in quick going, while the beefier M brakes provide strong and progressive stopping power.

Even a firm squeeze of the throttle can't side-step some hesitation as the turbo spools up before right foot pressure translates into forward momentum, but despite the sporty tune, ride quality is good (even riding on notoriously harsh 18-inch run-flat rubber), while response and road feel from the variable-ratio steering are excellent.

The eight-speed auto is beautifully slick, with manual changes, via wheel-mounted paddles, sharp and positive.

Add the grippy leather sports wheel, snug sports front seats, and racy cloth/Alcantara trim (leather in the convertible), and you have a comfortable, nicely balanced and fun-to-drive package.

Accelerating from 0-100km/h in 4.6sec (convertible 4.7sec), the M240i effortlessly achieves 'genuinely rapid' status. Yes, it's fast, but never furious, in the sense that even under the pressure of enthusiastic peddling it remains civilised and composed.

Maximum torque of 500Nm is not to be sneezed at, and when you realise that mountainous maximum is actually a flat-top plateau stretching from only 1520rpm up to 4500rpm, satisfying urge is never far away. And the flexible 3.0-litre turbo-six is an aural treat as it howls its way towards a 7000rpm rev ceiling.

The standard 'Adaptive M Suspension' offers settings from 'Comfort' through to 'Sport+', but even in the most forgiving mode the car remains taut and communicative.

The 18-inch rims, shod with Michelin Pilot Super Sport rubber (225/40 front / 245/35 rear) don't upset the ride as much as you'd expect, although coarse-chip surfaces send rumble through to the cabin.

In terms of ergonomics and general function, the new iDrive6 system is simple and intuitive to use, the current BMW dash and console layout is a model of efficiency, but the two-stage (depress small button on stubby lever, then shift) process to select drive or reverse can be a frustratingly hit-and-miss affair if you need to get going quickly.

Then, the M2 is all business, with a properly focused feel, and the ability to accelerate from 0-100km/h in a claimed 4.5sec for the six-speed manual, and just 4.3sec for the seven-speed dual-clutch. Try not to smile as that g-force shoves you back in your seat. You won't succeed.

Although peak power arrives at a relatively high 6500rpm, maximum torque of 465Nm (500Nm for limited periods on overboost) is ready for action across a broad spread from 1400-5650rpm, so the M2 has adrenalin flowing through its veins at all times.

An electronically controlled 'Active M Differential' manages torque distribution across the rear axle to optimise power down, with the ability to send anywhere from zero to 100 percent of drive to either back wheel.

The 'M Servotronic' steering, switchable through comfort and sport modes, is feelsome and linear in its response, the mega 'M Compound Brake' package (borrowed from big-brother M4) is professional grade, and while the seven-speed dual-clutch may shift faster, snicking up and down the manual's six ratios is a rare pleasure.

Rolling on 19-inch, ultra-high-performance Michelin semi-slick rubber (255/35 front / 275/35 rear) the M2 is never going to waft like a limousine, but if you're signing on for this kind of performance and dynamic ability, some ride harshness over less than perfect surfaces goes with the territory.

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.

BMW uses 'condition-based' servicing, with the car effectively telling you when it's time to visit the workshop, but the 'BMW Service Inclusive' program offers distance and time options to fix maintenance costs (on a 'Basic' or 'Plus' plan) for up to 10 years/200,00km.

For example, a five year/80,000km service package for the 2 Series costs $1340 for the Basic option (oil service/top-up, annual vehicle check, microfilter, air filter, fuel filter, brake fluid, spark plugs), and $3550 for the Plus pack (adds brake pads and discs, wipers rubbers, and clutch disc and plate).

The standard BMW warranty covers three years/unlimited km.

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.
