BMW 4 series


Audi S3

Summary

BMW 4 series

BMW's new 4 Series blasted onto the world stage with a chonky schnozz on it that only a mother could love. If BMW didn't want anyone to look at the rest of the car, it did a cracking job of it, because everyone had something to say about the big gnashers now grafted to the 4's front end.

I was nervous about it, too, because the 4 Series has always been so elegant and the current 3 Series - on which it is based - is quite nice to look at. It also threatened to overshadow just how good a car the BMW 4 should be, based as it is on the excellent 3 Series.

And, of course, one also had to wonder if a sports coupe like this would be any good around town. Limited vision? Hard to get in and out of? A true four-seater, or just a squishy 2+2? So many questions.

Audi S3

Audi was the first to market with a premium small performance sedan in 2014, with its four-door S3 combining luxury appointments with a punchy engine.

The German brand has largely enjoyed free air in the somewhat niche segment, but now Mercedes-AMG has launched its A35 sedan and BMW's 2 Series Gran Coupe-based M235i is set for a 2020 introduction to try and steal some of the S3's thunder.

With a new-generation version expected around the corner, Audi has updated its S3 with more kit to keep things fresh against its new rivals.

Now priced at $65,800 in sedan form, and $64,200 for the five-door Sportback hatch, does the S3 still have what it takes to stave off the competition?

Verdict

BMW 4 series7.8/10

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.


Audi S37.9/10

Despite being close to the end of its lifecycle, the Audi S3 sedan remains a solid choice for those looking for punchy performance wrapped in a premium package.

There is a bit of a trade-off in comfort for the extra performance, but it never strays towards being too unbearable or unliveable.

If you can survive with just using the rear seats occasionally, the S3 sedan also serves up one of the best front-seat interiors on the market, even after all this time.

Design

BMW 4 series

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.


Audi S38/10

Measuring 4466mm long, the sedan is 144mm lengthier than its hatchback sibling, but this also means there is about 50 litres more boot space.

While you might struggle to fit something like a full-sized bike into the boot of the sedan, the extra cargo capacity would easily accommodate extra grocery bags or a stroller.

We actually think the sedan looks better than the hatch, as the styling is a little more mature and grown up. It actually looks like a shrunk down A4!

The 19-inch wheels fitted to the S3 also help fill its slightly blistered wheelarches, while subtle nods to its sportiness can be seen in the red brake callipers and quad exhaust tips.

The rest of the S3 sedan is unmistakably Audi thanks to its singleframe front grille, strong shoulder line and contrasting side mirrors.

Inside, sports seats with Audi's unique diamond-quilting are fitted for the front occupants, while the rear bench seats also feature the bespoke finish – at least on the outboard pews.

Between the driver and front passenger sits a small storage cubby, the gear shifter, multimedia controls and two cupholders.

In the centre stack, you will see climate controls, the drive mode selector and a small screen above circular air vents.

Everything in the cabin is laid out in a clever, ergonomic fashion, though we will note the central cupholders won't be much use for anything bigger than a small coffee cup.

The best part of the interior is easily the virtual cockpit, which lays out all the information you need right in front of you. It's even customisable, so you can adjust the sizing of the satellite navigation maps or media system.

Practicality

BMW 4 series

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.


Audi S37/10

Being a small sedan, the S3 doesn't exactly boast heaps of interior space, but there is enough for a young family or a group of four adults over short distances.

Roughly the same size as a Mazda3 or Toyota Corolla sedan, the S3 will comfortably seat two adults in the front, but we found the rear headroom to be severely lacking.

Our head can just about fit in the rear outboard pews, but our necks were a bit sore after trying the middle seat. For reference, this writer measures about 186cm.

Leg room was pretty good though, even with the front seats set-up for someone our size, though again, we'd only recommend small children for the middle seat.

Amenities in the rear are sparse, with just a 12-volt socket to charge devices and rear air vents to keep passengers entertained.

The door cards will swallow small bottles, but not much else, while there is no fold down centre armrest or cupholders.

The front fares a little bitter, with larger door pockets, a glove box and central storage cubby, but don't expect to be moving houses in the S3 sedan.

As for the boot, its deep and wide with a cargo net to keep things tumbling round, and is generous enough to swallow 390 litres of volume with the seats in place – that's about 50L more than the Sportback.

Price and features

BMW 4 series

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.


Audi S38/10

Priced at $65,800 before on-road costs, the S3 sedan is about $6500 cheaper than its $72,500 Mercedes-AMG A35 sedan rival, but still comes loaded with what you'd expect in a premium small car.

Close to the end of its life, Audi bundled nearly $9000 worth of extras in the S3 sedan at no extra cost late last year, which includes the aforementioned 19-inch wheels, metallic paint, Nappa leather sports seats, wireless smartphone charger, magnetic suspension, and Bang & Olufsen 13-speaker sound system.

A sports bodykit is also fitted as standard, while LED headlights, keyless entry, push-button start, electronically folding side-view mirrors and heated front seats also feature.

Inside, passengers will find dual-zone climate control, LED interior lighting, flat-bottom steering wheel, and 7.0-inch multimedia system with digital radio, satellite navigation and Bluetooth connectivity.

Our favourite feature though, is the 12.3-inch all-digital virtual cockpit instrument panel, which is easily customisable and clear to read.

Audi set the benchmark for digital displays when it first introduced virtual cockpit in its third-generation TT sports car, and it still remains the benchmark to this day.

Engine & trans

BMW 4 series

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.


Audi S38/10

Power in the S3 sedan comes from a 2.0-litre turbo-petrol engine, which outputs 213kW at 6500rpm and 380Nm from 1850-5300rpm.

Drive is sent to the road via Audi's quattro all-wheel-drive system and seven-speed dual-clutch automatic transmissions, translating to a 4.8 second zero to 100km/h acceleration time.

Engine outputs are impressive for a small car, though the powerplant does run out of go when the needle approaches redline.

The engine is also down on power and torque when compared to its newer rivals, such as the 225kW/400Nm Mercedes-AMG A35 sedan and 225kW/450Nm BMW M135i xDrive – though the latter is a hatchback.

Fuel consumption

BMW 4 series

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.


Audi S37/10

Official fuel consumption figures are pegged at 6.5 litres per 100km, while carbon dioxide emissions are 151 grams per kilometre.

The S3 sedan sips premium unleaded fuel and the engine is Euro 6 compliant.

With a 55-litre fuel tank, the S3 should average about 846km of driving range per fill-up, but this is obviously dependent on driving conditions and the urgency of the driver's right foot.

Driving

BMW 4 series

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.


Audi S39/10

Audi has probably perfected the easy-to-drive-fast formula with its S3 sedan, deftly balancing approachable limits with an engaging drive.

The exhaust just pops, rather than crackles, but again, that characteristic lends itself more to the mature and grown-up status of the S3 rather than the ‘boy racer' image of other cars in the same class.

The quattro all-wheel-drive system means the S3 sedan just grips, but leans towards understeer if you really come into a corner red hot.

It's no bad thing though, as steering is communicative and the chassis feels neutral for the most part.

If you want a small luxury sedan that will make you feel like a hero, the S3 is it.

With peak torque available so early in the rev range, the S3 is also a gem when just cruising around at inner-city speeds and when getting off the line briskly.

The transmission shifts quickly and smoothly, but if you'd prefer, you can always put it in manual mode and shift with the gear stick or steering wheel mounted paddles.

The S3 then, is suitable for pulling double duty as a weekday commuter and weekend canyon carver, and while there are other options that will do each respective thing better, there isn't much out there that can balance both aspects.

Safety

BMW 4 series

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.


Audi S38/10

Audi's S3 comes fitted with adaptive cruise control, lane-keep assist, reversing camera, front parking sensors, blind-spot monitoring, rear cross-traffic alert and autonomous emergency braking.

ANCAP awarded the entire A3 line-up a full five-star safety rating when it was originally tested in 2013.

We'd love to see something like a surround view-camera added to the next-generation S3, but with its diminutive size, it's not a deal breaker.

Some sort of autonomous self-parking technology would also be appreciated to get the car into those tight spaces.

Ownership

BMW 4 series

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.


Audi S38/10

Audi's S3 sedan, like all new Audis, come with a three year/unlimited kilometre warranty alongside three years of roadside assist and 12 months of anti-corrosion cover.

Service intervals are ever 15,000km or 12 months, whichever comes first.

Both three- and five-year service plans are available for $1850 and $2390 respectively.
