Alpine A110

Summary

BMW M4

When it comes to cars, the letters B, M, and W carry huge credibility. But the extra letters and numbers that follow make all the difference.

A second M for example, means the hot rodders in the Munich maker's performance and racing skunkworks have played with everything from the drivetrain, aero and suspension, to the rims, rubber and interior design.

The number sitting next to it then determines whether you're looking at a compact firecracker (M2), fast-lane monster (M5), or bruising family truckster (X6 M). But every now and then some additional letters find their way onto even a BMW M car's bootlid.

In this case, a C and an S are significant additions to the already impressive M4 badge. They stand for Coupe Sport and were famously applied to BMW's achingly beautiful (E9) coupes of the late 1960s and early '70s.

So, with the howling echo of that all-time classic's in-line six ringing in its ears, the new M4 CS stands up as a proper high-performance coupe, pitched against the likes of Audi's recently reborn RS 5, the Lexus RC F, and Merc-AMG's soon-to-arrive C 63 S Coupe.

Does the CS legend live? Read on to find out.

Alpine A110

Dieppe. A pretty seaside community on the northern French coast. Established a mere thousand years ago, it's copped a hammering in various conflicts, yet retained its beautiful 'marine promenade', a handy reputation for top-notch scallops, and for the last 50-odd years, one of the world's most respected performance carmakers.

Alpine, the brainchild of one Jean Rédélé - racing driver, motorsport innovator, and automotive entrepreneur - is still located on the southern edge of town.

Never officially imported into Australia, the brand is virtually unknown here to all but committed enthusiasts, with Alpine having an illustrious rally and sportscar racing back-story including victory in the 1973 World Rally Championship, and the 24 Hours of Le Mans in 1978.

Rédélé was always committed to Renault, with the French giant eventually buying his company in 1973, and continuing to produce brilliant, lightweight road and racing Alpines until 1995.

After a close to 20-year hibernation, Renault reanimated the brand in 2012 with the stunning A110-50 concept racing car, and then the two-seat, mid-engine machine you see here, the A110.

It's clearly inspired by the Alpine of the same name that wiped the rallying floor clean in the early 1970s. Question is, does this 21st century version build or bury that car's iconic reputation?

Verdict

BMW M47.8/10

The BMW M4 CS is every bit as fast and engaging as you'd expect it to be. But be prepared for the day-to-day compromises that go with its pared back interior layout. It's beautifully engineered and dynamically excellent, but will have its hands full when Merc-AMG's similarly sized and priced (updated) C 63 S Coupe arrives shortly to rattle its cage.

Is the BMW M4 CS your kind of four-seat sledgehammer? Tell us what you think in the comments section below.

BMW offers the 'Service Inclusive' program, a one-off advance payment to cover scheduled costs at the 'Basic' or 'Plus' level.


Alpine A1107.9/10

Don't let the overall score fool you. The Alpine A110 is an instant classic. While practicality, safety and ownership costs don't set the world on fire, it delivers a driving experience that makes everything right with the world every time you get behind the wheel.

Design

BMW M48/10

The M4 in either entry-level Pure, or next-step-up Competition spec already looks like John Cena in a 10-year-old's t-shirt, with muscular bumps, curves and cuts extending aggressively in all directions. From its bulbous 'power dome' bonnet, to the pumped-up guards and gaping vents, the M4 screams 'don't argue'.

But this CS version borrows heavily from the track-focused M4 GTS (phased out earlier this year) and dials the aggro up a few notches.

A Matterhorn-sized bulge in the centre of the lightweight CFRP (Carbon-Fibre Reinforced Plastic) bonnet descends towards a broad air extraction vent that could double as a stormwater drain in bad weather.

The front, exposed carbon splitter is a slightly less accentuated version of the GTS's race-ready set-up, and the signature kidney grille is finished in menacing gloss black.

That black finish, part of the standard BMW Individual 'Shadow Line' package, also extends to the side-window trim, window recess covers, and vents on the front wings.

CFRP (unpainted this time) reappears on the roof, and an exposed carbon Gurney flap-style spoiler adds a touch of flash and aero efficiency to the bootlid. A nice match for the carbon diffuser below.

Suitably wide black alloy rims (19-inch front, 20-inch rear) further enhance the intimidating look, with twin LED headlights and an 'Organic rear lighting system', the latter another lift from the GTS, delivering an impressively vivid display.

The interior is familiar BMW territory, but it does feel like you've had a nasty break-up and your significant other has filled the moving van with all the luxury bits.

The leather and Alcantara trimmed sports seats are classy and racy enough, but the door cards are made from a natural-fibre composite BMW calls 'Nawaro'. There are no storage pockets, and you get a webbing strap to help pull the door closed.

Super lo-fi, and bafflingly, the 'armrest' slopes downward at an angle that, despite an Alcantara-trimmed pad, makes it just about impossible to actually rest your arm on it. Perhaps it adds some wheel-twirling elbow room, but for the other 99 per cent of the time it's just annoying.

Although trimmed in contrast-stitched Alcantara, the centre console is also a rudimentary affair, with no storage box between the front seats or adjustable air vents for rear-seat passengers. It might be good for weight saving, but it's not so great in terms of day-to-day practicality (which we'll get to shortly).

There's more Alcantara on the M Sport steering wheel (a leather wheel is a no-cost option) and dash-panel insert, with the CS designation neatly called out in mosaic-style lettering near the centre stack.


Alpine A1109/10

The final example of the original Alpine A110 rolled out of the Dieppe plant in 1977, and despite more than four decades separating it from this newcomer, the 2019 A110 is effectively a new-generation version.

Much more than a tip of the hat to a special predecessor, the new A110 perfectly updates the distinctive, purposeful look of its not-so-ancient ancestor.

In fact, head of the A110 design team, Antony Villain says, "We wondered; if the A110 never went away, if this new car was the sixth or seventh generation A110, what would it look like?"

Appropriately finished in a very French shade of 'Alpine Blue', our test example was one of 60 'Australian Premiere Edition' cars, and the design is full of intriguing details.

At just under 4.2m long, 1.8m wide, and only a touch over 1.2m high the two-seat A110 is compact to say the least.

It's raked LED headlights and round fog lights are recessed into the markedly curved nose in a complete and unabashed reload, with circular LED DRLs accentuating the throwback effect.

The overall look of the carefully scalloped bonnet is also familiar, with a huge under-bumper grille and side ducts creating an air curtain along the front wheel wells to finish off the treatment with a focused, technical touch.

A steeply raked windscreen runs up to a small turret with a broad channel running down its entre, and the flanks are narrowed by a lengthy, aero-influenced indent.

A case study in tightly wrapped surfacing, the rear-end is equally taut, with elements like 'X-shaped' LED tail-lights, tightly curved rear screen, single central exhaust outlet and aggressive diffuser continuing the expressive design theme.

Aero efficiency is a major influence, and as well as the diffuser careful inspection of the rear side window reveals a neat duct at its trailing-edge funnelling air to the mid/rear-mounted engine, and the underbody is smoothed near flat. An overall drag co-efficient of 0.32 is impressive for such a small car.

The A110 also proudly wears its French heart on its sleeve, with an enamel version of Le Tricolore attached to the C-pillar (and various points around the interior).

Eighteen-inch Otto Fuchs forged alloy rims fit the car's style and proportions perfectly with body-colour matching blue brake calipers poking through the delicate split-spoke design.

The interior is all business with racy Sabelt one-piece bucket seats setting the tone. Trimmed in a combination of quilted leather and microfibre (which extends to the doors) they are separated by a floating, flying buttress-style console housing key controls above and a storage tray (including multi-media inputs) below.

Highlights include cool body-colour panels in the doors, a Ferrari-like push-button gear selection set-up, slender alloy manual shift paddles attached to the steering column (not the wheel), matt carbon-fibre accents on the console and around the circular air vents, and a 10.0-inch TFT digital instrument cluster (which morphs to suit Normal, Sport or Track modes).

The A110's chassis and body are made from aluminium, with a brushed form of that material adorning everything from the pedals and perforated passenger footrest to multiple dash trim pieces.

Quality and attention to detail is outstanding to the point that just getting in the car feels like a special occasion. Every time.

Practicality

BMW M47/10

When it comes to cars, practicality is a subjective area. The M4 CS offers plenty of space for the driver and front-seat passenger, with room for two more in the back, as well as a decent boot. Practical, right?

But day-to-day details make all the difference and the drive to simplify the CS's cabin and reduce the car's overall weight has seen many common interior-storage options deleted.

The price CS owners pay for racy minimalism is a complete absence of door bins, no lidded box between the front seats, and no oddments tray in the middle of the centre console. Just a pair of cupholders ahead of the gearshift, and a shallow tray beyond that.

If you and a friend get into the car each carrying a standard load of personal junk like a phone, keys, wallet, and a beverage of some description, capacity is immediately exceeded.

Yes, you can shove all that 'stuff' into the (medium-sized) glove box, and that's probably the safer option anyway. But it's not as convenient as slipping things into strategically placed bins and boxes.

In terms of charging/connectivity there's a 12-volt outlet between the cupholders, and a single USB port oddly placed towards the rear of the centre console.

And while there are two seats in the back, getting to them requires the flexibility of a side-show contortionist, and the patience of a Tesla Model 3 reservation holder (the electric system that slides the front seat forward is glacially slow).

Even once you've managed to thread the needle through to the back, headroom is tight, so it's fine for kids and an occasional-only option for grown-ups. There are no cupholders or even a fold-down centre armrest back there, but there is a small, open oddments tray between the seats.

The boot offers a generous 445 litres of space and it's enough to easily swallow the CarsGuide pram or our three-piece hard suitcase set (35, 68 and 105 litres).

A cargo net is standard, there are four tie-down anchors, a small netted storage section behind the passenger side wheel tub, a cubby on the opposite side, shopping-bag hooks and conveniently placed handles, which release the 60/40 split-folding rear seat backs to liberate more room.

Don't bother looking for a spare wheel of any description. A repair/inflator kit is your only option.


Alpine A1106/10

Practicality is the oil to a two-seat sports car's water. If you want day-to-day functionality, look elsewhere. Quite rightly, the Alpine A110 puts driver engagement at the top of the priority list.

That said, with limited real estate to work with the car's development team has made it liveable, with a surprising amount of boot space included, and modest storage options snuck in around the cabin.

The heavily-bolstered, high-sided sports seats, necessitate use of the 'one hand on the A-pillar and swing in/out' technique for entry and exit, which won't suit everyone. And once inside several things are missing.

Glove box? No. If you need to refer to the owner's manual or grab the service book, they're housed in a small satchel attached to the bulkhead behind the driver's seat.

Door pockets? Forget it. Cupholders? Well, there's one, it's tiny, and located between the seats where only a double-joined circus contortionist could reach it.

There is a long storage bin under the centre console, which is helpful, although it's hard to reach in and actually extract things placed in it. Media inputs run to two USBs, an 'aux-in' and an SD card slot, but their location at the front of that lower storage area is tricky, and there's a 12-volt outlet just in front of the unreachable cupholder.

However, if you and a passenger want to head off on a weekend road trip, amazingly, you can take some luggage with you. With the engine located between the axles there's room for a 96-litre boot at the front and a 100-litre boot at the rear.

We managed to fit the middle (68-litre) hard suitcase from our three-piece set (35, 68 and 105 litres) in the broad but relatively shallow front boot, while the wider, deeper, but shorter rear boot is best for soft bags.

Another missing item is a spare tyre, with a neatly packaged repair/inflator kit your only option in the case of a puncture.

Price and features

BMW M48/10

In a classic less-is-more (money) scenario, the $189,529 BMW M4 CS cops a decent serving of standard features, but misses out on some of the luxury trimmings included on the next-rung-down M4 Competition ($156,710).

Standard inclusions run to adaptive LED headlights (including 'BMW Selective Beam' anti-dazzle tech), adaptive M suspension, combination 'Merino' leather/Alcantara seat trim, Alcantara-wrapped 'M' sports steering wheel (with blue/red stitching), a configurable head-up display, a 'BMW Individual' Anthracite roofliner, 'Comfort Access' (keyless entry and start), plus the 'iDrive6' multimedia system (managed via controller, touch or voice) running through an 8.8-inch, high-definition screen.

There are also big 10-spoke forged alloy rims, front-seat heating, sat nav, automatic headlights, rain-sensing wipers, front and rear park distance control, 'Surround View' parking assist, and the 'BMW ConnectedDrive' suite ('BMW Connected+' smartphone app, real-time traffic info, concierge services, and more).

That's a heavyweight equipment list for a car that's all about lightness. Inside, besides the basic door and centre console arrangement, the other significant concessions to kilo stripping are a 'specially adapted' 12-speaker version of Harman/Kardon's 'Surround Sound' audio system with DAB+ digital radio (16-speaker in the Competition), and a simplified, single-zone climate control set-up (dual-zone in the Competition).

Kind of like the CEO wearing a Swatch watch; they're wealthy and powerful, but 'all about performance', so they wear a functional, conspicuously un-flashy timepiece. They still live in a $10m penthouse apartment, though.


Alpine A1107/10

At $106,500 before on-road costs the Alpine A110 Australian Premiere Edition competes with an interesting range of similarly specified lightweight two-seaters.

The first that springs to mind is the achingly beautiful, mid-engine Alfa Romeo 4C Coupe at $89,000. For some, its exotic carbon chassis is underpinned by a too-firm suspension and the unassisted steering is difficult to deal with. For others (including me) it offers an exceptionally pure driving experience (and those that can't cop its physical nature need to harden up).

Lotus founder Colin Chapman's engineering philosophy, "Simplify, then add lightness" is alive and well in the form of the Lotus Elise Cup 250 ($107,990), and less than $10k more than the A110's MRRP delivers access to Porsche's thoroughbred 718 Cayman ($114,900).

Of course, part of the A110's substantial price tag relates to its all-alloy construction and the low-volume production techniques required to execute it. Not to mention development of an all-new design and global kick-start of a respected but dormant brand.

So, it's not all about bells and whistles, but for the record, a breakdown of this lightweight screamer's standard equipment list includes: 18-inch forged alloy rims, an 'Active-valve' sports exhaust system (with engine noise aligned to drive mode and speed), brushed aluminium pedal covers and passenger footrest, leather-trimmed Sabelt one-piece sports seats, auto LED headlights, satellite navigation, climate control air, cruise control, rear parking sensors, and electric heated, folding wing mirrors.

The 'Alpine Telemetrics' driving data system provides (and stores) real-time performance metrics including power, torque, temperatures, and turbo pressure, as well as lap times for track day warriors. And you'll also pick up a leather and microfibre-trimmed sports steering wheel (complete with 12 o'clock marker and Alpine Blue topstitching), stainless steel door sills with Alpine branding, dynamic (scrolling) indicators, auto rain-sensing wipers, and a 7.0-inch multimedia touchscreen including 'MySpin' mobile phone connectivity (with smartphone mirroring).

Audio comes from French specialist Focal, and although there are only four speakers, they're special. The main (165mm) speakers in the doors use a flax cone structure (flax sheet sandwiched between two glass fibre layers) and (35mm) aluminium/magnesium inverted dome tweeters sit at either end of the dashtop.

Certainly enough to be going on with, but at more than $100k we'd expect to see a reversing camera (more on that later), and the latest safety tech (more on that later, too).

Engine & trans

BMW M49/10

Like its E9 coupe forbear, the M4 CS is powered by an in-line six-cylinder engine, but things have moved on over the last 50 years, and the current (S55) engine offers a mechanical case study in the marriage of high-performance and efficiency.

The all-alloy unit features direct injection and twin turbos, the key drivers behind a stonking 600Nm of maximum torque (50kW up on the M4 Competition), available from 4000-5380rpm, and peak power of 338kW (+7kW), arriving at 6250 rpm.

It also features a 'charge air' (air-to-air) intercooler, 'Double Vanos' variable cam timing, and 'Valvetronic' variable valve lift (inlet and exhaust side).

The sleeveless cylinders use 'Electric Arc Wire Spray' technology to form a thin coating of iron on the cylinder walls, to save weight (no cast-iron liners) and reduce manufacturing complexity. And the engine's closed-deck design increases the block's torsional rigidity, enabling a substantial 10.2:1 compression ratio and use of a lightweight, forged crankshaft.

Transmission is a seven-speed 'M Double-Clutch' (M DCT) dual-clutch auto, complete with dedicated oil cooler, and drive is distributed across the rear axle via an electronically controlled, multi-plate 'Active M Differential'.


Alpine A1109/10

The Alpine A110's (M5P) all-alloy 1.8-litre turbo-petrol four-cylinder engine is closely related to the unit found under the bonnet of the Renault Megane R.S.

Alpine has modified the intake manifold, exhaust and overall calibration, but the big difference here is that although it's still transversely mounted, in the Alpine the engine sits in a mid/rear position and drives the rear wheels (rather than in the R.S.'s nose driving the fronts).

Featuring direct injection and a single turbo it produces 185kW at 6000rpm, and 320Nm of torque from 2000-5000rpm, compared to 205kW/390Nm in the Megane R.S. But the Alpine's 356kg weight advantage means it boasts a 169kW/tonne power-to-weight ratio, while the Megane sits at 141kW/tonne.

Drive goes to a Getrag-sourced seven-speed (wet) dual-clutch auto transmission, with Alpine-specific ratios inside.

Fuel consumption

BMW M48/10

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 8.3L/100km, the twin-turbo six emitting 194g/km of CO2 in the process. 

Over roughly 350km of city, suburban and freeway driving (much of it 'enthusiastic') we recorded 10.9L/100km (at the bowser) An impressive number for such a strongly performance-focused machine.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 60 litres of it to fill the tank.


Alpine A1108/10

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.2L/100km, the 1.8-litre four emitting 137g/km of CO2 in the process.

Over close to 400km worth of often 'enthusiastic' driving, taking in city, suburban and freeway running we recorded an average of 9.6L/100km.

Definitely a miss, but not bad when you consider we hit the off switch for the standard stop-start system on a consistent basis and regularly took advantage of the accelerator pedal's ability to move towards the floor.

Minimum fuel requirement is 95 RON premium unleaded, and you'll need just 45 litres of it to fill the tank.

Driving

BMW M48/10

Let's get it out of the way. The M4 CS is fast. Anything running 0-100km/h in less than four seconds gains admission to a seriously rapid club, and BMW claims 3.9sec for this car (an exact match for the soon-to-arrive Merc-AMG C63 S Coupe).

We might have given the standard launch-control system a go, and may be able to confirm straight-line acceleration from step-off will compress your chest like an over-zealous lifesaver at CPR practice.

But just as impressive is the in-gear thrust, with 80km/h to licence loss (120km/h) covered in only 3.4sec. Which plays to the twin-turbo six's strength, with maximum torque arriving at a relatively high 4000rpm, and remaining on tap until 5380rpm.

Power doesn't reach its peak until 6250rpm, with the rev ceiling sitting at 7600rpm; impressively high for a twin-turbo engine.

Everything from the DSC, ABS, and active suspension to the active diff, electrically assisted steering and seven-speed, dual-clutch transmission has been tuned specifically for the M4 CS.

The 'M DCT' auto is agreeably civilised at parking speeds, yet shifts positively and rapidly, especially in manual mode, under pressure at higher pace.

An M Sport exhaust system features electronically controlled flaps sitting directly in front of the rear mufflers, and varies the intensity of the accompanying soundtrack according to drive mode and level of aggression. It sounds suitably angry, but those hoping for the soaring purity of say the (S54) naturally aspirated in-line six found under the bonnet of the E46 M3 will be left hankering for the good old days.

Front suspension is a modified MacPherson strut design, with a five-link set-up at the rear, and data from wheel-acceleration sensors on each corner is used to recalibrate each damper's setting every 2.5 milliseconds.

The drivetrain, suspension and steering can each be dialled into 'Comfort', 'Sport' or 'Sport+' modes, and the CS's ride changes markedly in the switch from Comfort to Sport; the former proving compliant and smooth rolling over rough city surfaces, and the latter keeping things reassuringly buttoned down on a B-road blast.

Although BMW says that, unlike the M4 GTS, it has deliberately steered the M4 CS away from a focus on the circuit (no roll cage, no adjustable splitters or spoilers) we'd suggest it's best to keep the Sport+ suspension setting for track days unless you're already planning on replacing some of your older fillings.

Speaking of track days, BMW says the M4 CS's dynamics were “honed on the Nurburgring Nordschleife” where it's recorded a best lap time of 7:38, which is as fast as a Ferrari 458 Italia and Lexus LFA. That's very, very impressive.

At 1580kg the M4 CS is 35kg lighter than the M4 Competition (1615kg), and just five kegs under the Pure (1585kg), so despite all the light-weighting hype it's worth remembering we're still looking at a car tipping the scales at just under 1.6 tonnes.

The electromechanical steering can also be tuned through the three performance modes, and Sport delivers the best combination of quick turn-in, agreeably linear assistance and decent road feel.

But putting the CS's power down out of even moderately quick, tight corners is less convincing. The big forged-alloy rims (19-inch front, 20-inch rear) are shod with ultra-high-performance Michelin Pilot Sport Cup 2 rubber (265/35 front – 285/30 rear).

Squeezing the power in smoothly but quickly, the semi-slick tyres feel like they need more heat in them. Without going anywhere near the DSC's more taily 'M Dynamic' modes, and despite the active diff, the rear of the car will squirm when fed full throttle acceleration on corner exit, unsettling overall balance. Less edgy Michelin Pilot Super Sport tyres are a no-cost option.

The standard M sport front seats look the part (the M4 logos in the backrest illuminate!) and grip firmly without any discomfort for this 183cm tester.

And when it comes to slowing everything down, the standard brakes run to big ventilated discs front and rear, clamped by four-piston calipers at the front, and two-piston at the rear.

Our test example was optioned with the $15,000 'M carbon ceramic' package featuring humungous carbon rotors, thumping six-piston calipers up front, and four-piston rear. For that money you'd expect Le Mans-style braking performance, and while we didn't exactly put them to a 24-hour high-speed test, firm application of the left-hand pedal will consistently stand the car on its nose.


Alpine A11010/10

Weighing at just 1094kg (target weight was 1100kg), with a 44:56 front-to-rear weight distribution, the all-aluminium A110 is every millimetre the mini-supercar you'd hope it to be.

It only takes two to three rotations of the Alpine's wheels to realise it's exceptional. The Sabelt seat is superb, the chunky steering wheel perfect, and the engine instantly eager to get on with it.

The electro-mechanical power-assisted steering feels just right from the first corner. The rack is quick and road feel is intimate without the crashy feedback penalty paid by the Alfa 4C.

Engage launch control and you're blasting from 0-100km/h 4.5sec, with the engine adding a suitably raucous backing track, a full charge of air rasping through the inlet manifold just behind your ears. Spinning up to the close to 7000rpm rev ceiling is pure pleasure, with peak torque available from just 2000rpm all the way to five grand.

Pressing the wheel-mounted 'Sport' button sharpens gearshifts and holds low ratios for longer, with the already slick dual-clutch really getting its race face on. Hold in the down lever in manual mode and the transmission will instantly shift through to the lowest gear engine revs will allow, the Active-valve sports exhaust chipping in with rude pops and bangs on the over-run. 'Track' mode is even more hardcore, allowing a greater element of slip in cornering. Brilliant.

The engine's mid/rear location delivers a low roll-centre and the double wishbone suspension set-up (front and rear) manages to combine super-sharp dynamic response with a surprisingly civilised ride.

Alpine says the A110's light weight and ultra-rigid chassis mean its coil springs can be reasonably soft and anti-roll bars light so even our truly ordinary urban blacktop doesn't cause too much distress.

The A110 is beautifully balanced, amazingly agile, and satisfyingly precise. Weight transfer in quick cornering is managed to perfection, the car remaining stable, predictable and hugely entertaining.

Grip from the Michelin Pilot Sport 4 rubber (205/40 fr - 235/40 rr) is tenacious, and the torque vectoring system (by braking) quietly keeps things pointing in the right direction if an over-zealous pilot begins to overstep the mark.

Despite the A110's modest kerb weight braking is professional grade. Brembo provides ventilated 320mm rotors (front and rear) with four-piston alloy calipers at the front and single-piston floating calipers at the rear. They're progressive, powerful and consistent.

The only downsides are a clumsy multimedia interface, and the annoying lack of a reversing camera. But who cares, this car is amazing.

Safety

BMW M47/10

The BMW 4 Series (and by extension the M4 CS) hasn't been assessed for crash safety by ANCAP or EuroNCAP, but boasts a solid array of active and passive safety tech, with several notable omissions.

To help you avoid a crash the M4 CS features ABS, brake assist, EBA, EBD, 'Cornering Brake Control' (CBC), Dynamic Stability Control (DSC), Dynamic Traction Control (DTC) and dry braking, 'Emergency stop signal', lane-departure warning and a tyre-pressure-monitoring system.

M4 owners also receive a complimentary BMW Intensive Driving Experience course (one person per vehicle purchase), which is arguably the best crash prevention measure of all.

But significantly, there's no AEB (Auto Emergency Braking) or other, more recent safety bits and pieces (found on other current BMW models) like blind-spot monitoring, forward-collision warning, fatigue detection, reverse collision avoidance, or speed-sign recognition and warning.

If all else fails and a collision is unavoidable passive safety tech runs to head and side airbags for the driver and front passenger, as well as curtain airbags covering front and rear. But again, things like an active bonnet and active front head restraints, fitted elsewhere in the BMW world, are MIA.

There are ISOFIX child-restraint anchors with top tether points in each of the rear seat positions.


Alpine A1107/10

In terms of active safety, the A110's sheer dynamic ability will help you avoid an unfortunate incident, and specific tech includes ABS, EBA, traction control, stability control (disconnectable), cruise control (with speed limitation) and hill-start assist.

But forget about higher order systems like AEB, lane keeping assistance, blind spot monitoring, cross traffic alert or adaptive cruise.

And when it comes to passive safety you're protected by an airbag for the driver and one for the passenger. That's it. Weight-saving, eh? What can you do?

The Alpine A110 hasn't been assessed for safety performance by ANCAP or EuroNCAP.

Ownership

BMW M47/10

Warranty cover is three years/unlimited km, with 24/7 roadside assistance included for three years, and additional support from BMW 'Servicemobiles' (07:00 – 23:00 every day) staffed by trained techs and stocked with key service parts.

Maintenance on all BMW 4 Series models is controlled by a 'Condition Based Servicing' system which piles real-time data (mileage, time since last service, fuel consumption, and how the car has been driven) into a specific algorithm to determine whether an annual vehicle inspection or (oil) service is due.


Alpine A1107/10

The Alpine A10 is covered by a three-year/100,000km warranty with a twist. According to Alpine, the first two years are covered for unlimited kilometres. And if at the end of the second year total kilometres remain less than 100,000, the warranty continues into a third year (still to an overall cap of 100,000km).

So, you can sail over the 100,000km mark in the warranty's first two years, but that means you won't get a third.

Complimentary roadside-assist is provided for 12 months, continuing for up to four years if your Alpine is regularly serviced at an authorised dealer.

There are currently three dealers only – one each in Melbourne, Sydney and Brisbane – and service is recommended every 12 months/20,000km, with the first two costing $530 each, and the third ramping up to $1280.

You'll also need to factor in a pollen filter ($89) at two years/20,000km and accessory belt replacement ($319) at four years/60,000km.
