Hyundai I20 vs BMW 4 Series

What's the difference?

The i20 N hatch is so much fun, and not in a special occasion kind of way. It’s an affordable, compact performance car that’ll put a smile on your face no matter where or when you drive it. The Fiesta ST and Polo GTI have a worthy new playmate. I love it!

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

Hyundai’s current WRC challenger may be a coupe but this angry little five-door hatch absolutely looks the part.

We’re assured the N is the only current-generation i20 we’ll see in the Aussie market, and it runs with a relatively low (101mm) ground clearance, a grille pattern inspired by a chequered flag, black mirror shells, and menacing, angular LED headlights.

The ‘Satin Grey’ 18-inch alloys are unique to this car, as are the side skirts, raised rear spoiler, darkened LED tail-lights, a ‘sort-of’ diffuser under the rear bumper and a single fat exhaust exiting on the right-hand side.

There are three standard paint options - ‘Polar White’, ‘Sleek Silver’, and N’s signature shade of ‘Performance Blue’ (as per our test car) as well as two premium shades - ‘Dragon Red’, and ‘Phantom Black’ (+$495). A contrasting Phantom Black roof adds $1000.

Inside, the N-branded sports seats, trimmed in black cloth, featuring integrated headrests and blue contrast stitching, are unique to the i20 N. There’s a leather-trimmed sports steering wheel, handbrake lever and gear knob, as well as metal finishers on the pedals.

The 10.25-inch digital instrument cluster and same-sized multimedia screen look slick, and ambient lighting heightens the hi-tech mood.

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

Although it’s just 4.1m long, the i20N is impressively space efficient with decent room up front and a surprising amount of head and legroom in the back.

Sitting behind the driver's seat, set for my 183cm position, I had plenty of head and legroom, although, understandably, three people across the back will need to be kids or understanding adults, on a short journey.

And there are plenty of storage and power options, including the wireless device charge pad in front of the gear lever, which doubles as an oddments tray when not in use, two cupholders in the front centre console, door bins with room for large bottles, a modest glove box and a lidded cubby/armrest between the front seats.

No armrest or air vents in the back, but there are map pockets on the front seat backs, and again, bins in the doors with room for bottles

There is a media USB-A socket and another for charging, as well as a 12V outlet in the front, and another USB-A power socket in the back. Hyundai suggests the latter could be handy for powering track day cameras. Great idea!

Boot space is impressive for such a compact hatch. With the rear seats upright there’s 310 litres (VDA) available. Fold the 60/40 split-folding rear backrest and no less than 1123 litres opens up.

A dual-height floor can be flat for long stuff, or deep for tall stuff, there are bag hooks provided, four tie down anchors, and a luggage net included. The spare is a space saver.

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

We’re in a zone some way North of $100K here with cost-of-entry running to $115,900, before on-road costs. So, as well as the included powertrain, suspension, and safety tech you should rightfully be expecting a lengthy standard features list.

And the M440i Gran Coupe goes toe-to-toe with its heavyweight Euro competition, featuring three-zone climate control air, adaptive cruise control, ‘Laserlight’ headlights, that 12.3-inch ‘BMW Live cockpit Professional’ instrument display and 10.25-inch ‘Control Display’ multimedia touchscreen managing navigation, the 16-speaker/464W harmon/kardon Surround Sound audio system (with Apple CarPlay and Android Auto integration) and a host of other on-board functions.

There’s also the ‘Vernasca’ Black leather trim, an electric glass sunroof, the leather-trimmed sports steering wheel, the electric sports front seats are heated and there’s wireless charging for compatible devices.

The i20 N is powered by a turbo intercooled 1.6 litre four-cylinder petrol engine, driving the front wheels via a six-speed manual gearbox and Torsen-type mechanical limited slip differential.

The all-alloy (G4FP) engine features high-pressure direct-injection and an overboost function, producing 150kW from 5500-6000rpm, and 275Nm from 1750-4500rpm (rising to 304Nm on overboost at max throttle from 2000-4000rpm).

And the engine’s mechanical ‘Continuously Variable Valve Duration’ set-up is something of a breakthrough. In fact, Hyundai claims it as a world’s first for a production engine.

Not timing, not lift, but variable duration of valve opening (managed independently of timing and lift), to strike the optimal balance between power and economy across the rev range.

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

Hyundai’s official fuel economy figure for the i20 N, on the ADR 81/02 - urban, extra-urban cycle, is 6.9L/100km, the 1.6-litre four emitting 157g/km of C02 in the process.

Stop/start is standard, and we saw a dash-indicated average of 7.1L/100km over several hundred km of city, B-road and freeway running on the occasionally ‘spirited’  launch drive.

You’ll need 40 litres of ‘standard’ 91 RON unleaded to brim the tank, which translates to a range of 580km using the official figure and 563 kays using our launch test drive number.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

Unusually for a manual car, the i20 N features a launch control system (with an adjustable rpm setting), which we found fiddly to get working, but with or without it, Hyundai claims a snappy 0-100km/h time of 6.7sec.

And it’s such a pleasure to steer a car with a slick-shifting manual gearbox. The six-speed unit features a rev-matching function accessed via the press of a racy red button on the steering wheel. 

Buf for those who prefer an old-school, double-shuffle, heal-and-toe tap dance across the pedals, the relationship between the brake and accelerator is perfect. 

And if you’re keen on Walter Rohrl-style left-foot braking, to help steady the car or steer it in fast cornering, the ESC is switchable through to Sport mode or completely off, allowing fuss-free simultaneous brake and throttle application.

There’s even a shift-timing indicator near the top of the instrument cluster, with colour bars closing in on each other as the tacho needle pushes towards the rev limiter. Fun.

Engine and exhaust noise is a combination of a raspy induction note and adjustable crackle and pop out the back, courtesy of a mechanical flap in the exhaust system, adjustable through three settings in N mode.

Traditionalists may not be thrilled by the addition of in-cabin synthetic enhancement of all of the above, but the net effect is thoroughly enjoyable.

It’s worth remembering in this context N stands for Namyang, Hyundai’s sprawling proving ground south of Seoul where the car was developed, and the Nürburgring where this go-fast i20 was fine-tuned.

The body has been specifically reinforced at 12 key points, along with additional welds, and “bolt-in underbody structures” to make the i20 N stiffer and more responsive.

The strut front, coupled (dual) torsion beam rear suspension has also been set up with increased (neg) camber and a revised anti-roll bar at the front, as well as specific springs, shocks and bushings.

A compact, mechanical LSD is added to the mix, and grippy 215/40 x 18 Pirelli P-Zero rubber was produced specifically for the car and is stamped ‘HN’ for Hyundai N. Impressive.

The end result is outstanding. Low-speed ride is firm, with suburban bumps and lumps making their presence felt, but that’s what you’re signing on for in a hot hatch at this price point.

This car feels balanced and well buttoned down. Power delivery is agreeably linear and at a fraction over 1.2 tonnes the i20 N is light, responsive and nimble. Mid-range urge is strong.

Steering feel is good, with assistance from a column-mounted motor taking nothing away from an intimate connection with the front tyres.

The sports front seats proved grippy and comfortable over long stints behind the wheel, and playing with the multiple N drive modes tweaking the engine, ESC, exhaust, and steering just adds to the involvement. There are twin N switches on the wheel for quick access to custom set-ups.   

And that Torsen LSD is brilliant. I tried my best to provoke a spinning inside front wheel on the exit of tight corners, but the i20 N just puts its power down without so much as a chirp, as it rockets towards the next bend.

The brakes are 320mm vented at the front and 262mm solid at the rear. Calipers are single piston, but they’ve been beefed up and fitted with high-friction pads. The master cylinder is bigger than the standard i20 and the front rotors are cooled by lower control arm mounted air guides blowing through vented knuckles.

The launch i20 N fleet of around half a dozen cars copped an hours long hot lap pounding at Wakefield Park Raceway, near Goulburn NSW without drama. They’re well up to the task. 

One niggle is a large turning circle. The data sheet says 10.5m but it feels like the car is carving a wide arc in U-turns or three-point turns.

A 2580mm wheelbase between the bumpers of a 4075mm car is substantial, and the steering’s relatively low gearing (2.2 turns lock-to-lock) no doubt has a lot to do with it. The price you pay for quick turn-in.

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

Active crash-avoidance tech in the M440i xDrive Grand Coupe is impressive with AEB standard, as well as lots of assistants and warnings, namely: ‘Steering and Lane Control Assistant’, ‘Cross Traffic Warning’ (front and rear), ‘Lane Keeping Assistant’ (with ‘Lane Departure Warning’ and ‘Lane Change Warning’), ‘Crossroads Warning’, ‘Evasion Assistant’, and ‘Parking Assistant Plus’ (including ‘3D Surround View and Reversing Assistant’).

If an impact is unavoidable there are six airbags on-board (driver and front passenger front and side, plus side curtains) as well three top tethers and two ISOFIX positions for child seats in the second row.

Plus an ‘Intelligent Emergency Call’ function automatically dials back-to-base if the car has been involved in a crash, and a comprehensive first aid kit is on-board. 

The BMW scored a maximum five-star ANCAP assessment in 2019.

Hyundai covers the i20 N with a five year/unlimited km warranty, and the ‘iCare’ program includes a ‘Lifetime Service Plan’, as well as 12 months 24/7 roadside assist and an annual sat nav map update (the latter two renewed free-of-charge each year, up to 10 years, if the car is serviced at an authorised Hyundai dealer).

Maintenance is scheduled every 12-months/10,000km (whichever comes first) and there’s a pre-paid option which means you can lock in prices and/or fold service costs into your finance package.

Owners also have access to the ‘myHyundai’ online portal providing details on the car’s operation and features as well special offers and customer support.

Service for the i20 N will set you back $309 for each of the first five years, which is competitive for a hot hatch in this part of the market. 

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750.
