BMW M4 vs Aston Martin DB12

What's the difference?

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

Typically when a car company makes a bold claim in their press release it's hyperbole designed simply to grab attention. But in the case of the DB12, Aston Martin truly has built something different than before, elevating it beyond its previous ‘Grand Tourer’ status.

While ‘Super Tourer’ may be a bit dramatic in name, this is a very impressive car across the board. It’s fast, fun, luxurious, comfortable, opulent, stylish and liveable, so while it may require a heavy financial investment, you are duly rewarded.

Plus you also get to pretend to be James Bond…

The M4 CS is familiar in all the right ways, but definitely looks significantly jacked up compared to its lesser siblings.

Part of that is the extensive use of carbon everywhere, from its bonnet panels to its roof, front lip, side skirting and boot spoiler. But also because of its super-muscular angles and creases, including the huge dome in its bonnet.

Also exclusive to this M4 CS is the light treatment, with the front LEDs lighting up with yellow highlights the brand says are supposed to be reminiscent of GT racing cars.

At the back, the rear lights are flush with fibre optic lighting, lending a flowing and unique light signature that looks epic at night.

Inside, it's a sea of carbon, with the lightweight racing seats, the dash inserts and the centre console all lined in it. It is a perfectly finished space, though, and one that's also flecked with red, including a 12 o'clock band on the thick-rimmed steering wheel, the seat backs, the contrast stitching and the paddle shifts.

Be warned, though, it takes some acrobatics to climb into or out of the CS. The seat bottoms have these super high edges that double as grab handles, but require some awkward contortions to navigate.

In short, it looks angry, this M4 CS, inside and out.

Personally, I felt like Aston Martin peaked with its ‘DB’ design nearly two decades ago with the DB9. It was a masterpiece of simplicity, elegance and heritage and the subsequent DB11 just looked more fussy and complicated for the sake of being different.

The DB12 manages to correct that mis-step from the designers, getting back to the classic silhouette of an Aston Martin, maintaining the trademark elements (specifically the unique grille shape) and the elegance of simplicity.

Aston Martins don’t need to be attention-grabbing like a Ferrari or Lamborghini. Instead, they attract attention with an understated but unmissable presence that just attracts eyeballs. You don’t need to know anything about cars to know that the DB12 is a very expensive, luxury sports coupe - it says all that the second you get a look at it.

The interior of DB12 looks and feels every bit as prestigious as the exterior does. High-quality materials have been used throughout and there is a level of fit and finish that elevates beyond most other cars on the market. It feels like a hand-made car, built with patience and detail, rather than something rushed down a production line.

The cabin design itself manages to feel both classical and modern, in the same way the exterior takes inspiration from Aston Martins of previous years but gives them a 21st century update.

It all boils down to how you classify practicality in a car like this. I mean, the basic stuff is all there – it's got two doors, four seats and a boot capacity of 440 litres.

It measures 4801mm in length, 1918mm in width and 1399mm in height, and room for front seat riders is good, but less so for anyone you squeeze into the back. There are even ISOFIX points for a child seat.

But if you consider practicality the practical pursuit of performance, then the M4 CS has plenty of perks.

Inside Aston Martin’s designers have understood the typical customer isn’t a Gen Alpha who does everything on their smartphone, so there’s a neat array of proper buttons, switches and dials to take care of all the functions without taking your eyes off the road. If you are into technology you may be disappointed by the relatively small infotainment screen, but from a usability perspective it does the job well.

As you’d expect the level of fit and finish is impressive and the diamond quilting on the leather seats looks exceptional. The seats themselves are comfortable and supportive, with generous cushioning rather than the sportier, less comfortable seats found in purebred sports cars.

The DB12 is a 2+2, with a pair of seats in the rear, but to be frank you’d need to be desperate to use them. They are ‘emergency use only’ seats that will deeply compromise the front seat occupants just to squeeze anyone in the back.

Value is relative at this point in the market, as the DB12 is priced from $455,000 before on-road costs and any personalisation. For that price you do get a lengthy list of standard features you’d expect on a premium vehicle, including 21-inch forged alloy wheels, LED daytime running lights and tail-lights, keyless entry and ignition, 12-way electronically adjustable front seats, wireless phone charging, navigation, Apple CarPlay and a 390-watt 11-speaker Aston Martin sound system.

Of course, that’s what you should probably expect of much cheaper luxury cars. So on top of that there’s the high level of presentation, including both externally and in the cabin, with high-quality materials used across the entire vehicle.

Then there’s the ‘badge value’ that having an Aston Martin brings to the equation, which helps to play a part.

Finally, there’s how it compares when lined up against its competitors and on that front the DB12 looks well placed. The similarly powered Mercedes-AMG GT starts at $366,500, while V6-powered Maserati GranTurismo begins at $375,000 but the outgoing Ferrari 812 Superfast is priced at more than $600,000.

All things considered, the DB12 feels competitively priced and good value for this upper echelon of the new-car market.

BMW has found yet more grunt lurking in its trusty 3.0-litre 'M TwinPower' six-cylinder petrol engine, with the M4 CS now pumping out 405kW and 650Nm.

That's a decent jump from the 390kW and 620Nm served up by the M4 Competition, and a giant leap from the outputs of the 'base' M4 – 353kW and 550Nm.

Predictably, then, the CS is the fastest of the lot, knocking off the run from 0-100km/h in 3.4 seconds, compared to 3.5 and 4.2 in the Competition and M4, respectively. The top speed is also dialled up to 302km/h.

All that power is channeled through an eight-speed automatic and sent to all four wheels on demand, with the help of an 'Active M Differential'.

Aston Martin was once famous for its V12 engines, but with the brand changing hands so many times over the years and the pressure to develop increasingly expensive powerful, yet fuel-efficient engines means the brand now outsources some of its powertrains. So while the brand is developing a new V12 engine, the DB12 is powered by the 4.0-litre twin-turbo V8 built by Mercedes-AMG.

While Aston Martin fans may bemoan the use of a German engine in this British car, the truth is it’s a much better engine than the previous V12 used in the DB11, Vantage and other models. It offers up 500kW/800Nm and delivers all that performance in a broad spread across the rev range (unlike the old V12).

It gives the DB12 a sportier, more urgent and responsive driving character than its predecessors and helps to explain the new ‘Super Tourer’ name. Aston Martin claims it can run 0-100km/h in just 3.6 seconds and has a top speed of 325km/h.

The M4 CS is fitted with a 59-litre fuel tank, which – given the BMW's official fuel claim of 10.2 litres per hundred kilometres – should deliver a driving range on a full tank of 541 kilometres.

But... BMW also says the regular M4 – you know, the one that makes 52 fewer kilowatts and 55Nm less torque – uses 10.1L/100km, so do with that information what you will.

Aston Martin claims a combined fuel cycle return of 12.2 litres per 100km, which is not what you would call sipping the unleaded, but given this is a large, grand tourer (sorry, Aston Martin, Super Tourer) it’s actually a solid return. If you’re in the market for a car like this, anything sub 15L/100km should be considered acceptable; if you’re worrying about emissions or the cost of petrol you probably shouldn’t be buying a $455k sports car.

Unfortunately we didn’t have the DB12 long enough to get a real-world fuel economy figure, so we’ll just have to take Aston Martin’s word for it.

With its 78-litre tank the DB12 does have a theoretical driving range of approximately 630km.

The hardest and angriest M4 of all time is, perhaps unsurprisingly, hard and angry. This is a race track specialist, but because I don't happen to own one of those, my first experience with the barking (and barking mad) M4 CS was navigating my way back from BMW's inner-city dealership.

Like it or lump it, you're going to read some Porsche comparisons here, because you're talking not too far off base 911 Carrera money, and suddenly I find the two Germans doing battle for a spot in my dream garage.

First things first, the BMW won't be much chop for daily driving for most people. Happily, I have a sickness for uncomfortable sports cars. It tells me that no compromises have been made in the pursuit of punishing performance.

A good thing, too, because the BMW, at city speeds, can be punishing. Everything feels heavy, the seats aren't overly comfortable – especially the hard bits that tend to dig in when cornering – and it stiff-arms its way over road imperfections, that exhaust booming and barking as it does.

Again, I loved it, and you probably will, too. But it's still not the kind of car I'd relish sitting in the morning peak hour rush in.

But escape the confines of the city and the BMW M4 CS suddenly makes a whole heap of sense. The acceleration is genuinely brutal, and wonderfully theatrical, with that quad-tipped titanium exhaust barking and snarling as you rocket towards 100km/h.

The steering is brilliant, with feedback fed to your wrists via that thick-rimmed wheel, and the entire experience feels sharp, super engaging and edgy.

You can push the M4 hard and fast, and I'm certain my limited talents would run out far before the BMW's would, but there's this thrilling sense of peril sparked by the aggression of the experience, that I love.

It's like the magic of a roller-coaster, I guess. Even if you know nothing is going to happen, you never really know, right? And in that lies the magic.

But back to original question, this or a Porsche 911? There's no doubt a Carrera is a better all-rounder, in terms of comfy commuting and race track fun, but this angry M4 is all shouty theatrics, all of the time.

I bloody love it.

The defining characteristic of a ‘Grand Tourer’ is that while fast, they aren’t typically agile and as responsive as a sports car. In other words, a grand tourer is best suited to a long, cross-country trip on faster, flowing roads, rather than a winding mountain pass or twisty switchbacks.

So, in keeping with the ‘Super Tourer’ theme that the brand is selling, the DB12 is notably more responsive and therefore more engaging to drive across any condition. It still has the comfortable, laid-back nature of a ‘GT’ but when you want to have some fun it’s capable of hiding its size and feeling very sporty.

The handling is highlighted by how quickly the front end of the car reacts. Typically with this front-engined 'GT' cars you feel like you're sitting at the very back of the car, so it feels slow to respond to inputs and that can create a feeling of laziness. But not in the DB12. The front end feels sharp and responsive, making you feel like you are right at the centre of the action.

It's helped by the engine that feels lighter than the old V12s but more urgent with its power delivery, too. It adds to that feeling of a more sporty and focused driver's car, rather than a 'GT' for just soaking up the kays. It shouldn't be surprising though, AMG doesn't really build relaxed, laid-back engines, rather ones designed for maximum excitement - and that's what the DB12 delivers when you bury your right foot.

Remarkably, it also plays the role of ‘daily driver’ well too. Which is an unusual way to think of a car like this, but for those fortunate enough to have the means to afford it, the DB12 could ferry you from home to work and back again in luxury and comfort.

The DB12 comes equipped with a lengthy list of active safety features as part of its Advanced Driver Assistance System (ADAS). These include adaptive cruise control, traffic sign recognition, lane keep assist, lane departure warning, lane change assist, front and rear cross traffic assist, driver drowsiness detection and hands-off detection.

There’s no ANCAP rating or equivalent, as crash testing these kinds of low-volume sports cars is unheard of from the safety authorities.

The M4 CS is covered by BMW's five-year, unlimited-kilometre warranty, with condition-based servicing available in packs, which will cost you $3530 over five years/80,000km, or $2900 over four years/60,000km.

The standard Aston Martin warranty covers three years/unlimited kilometres, which is unusually short by current industry standards; a curious case of the top end of the market lagging behind the mainstream brands.

Servicing is handled by individual dealers, so there’s no set cost structure, but the intervals are every 12 months/16,000km. Instead you’ll need to discuss what sort of costs are involved with keeping your DB12 running smoothly when you speak to a salesperson.
