Aston Martin DB11
It might look like a stealth fighter, but this dramatic example of Aston Martin’s DB11 AMR didn’t fly under anyone’s radar during its time in the CarsGuide garage.
Forget the Duke and Duchess of Sussex, this piece of British royalty caused jaws to drop and camera phones to rise more effectively than any mere ginger celebrity or ex-TV trouper.
AMR stands for Aston Martin Racing, and this performance flagship replaces the ‘standard’ DB11, delivering even more fire under the hood and fury from the exhaust. Aston also claims it’s faster, dynamically superior, and sleeker on the inside.
In fact, the DB11 AMR’s 5.2-litre twin-turbo V12 now produces enough grunt to accelerate it from 0-100km/h in just 3.7 seconds.
More than just a flash Harry, then? Let’s find out.

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.

The Aston Martin DB11 AMR is fast, capable and beautiful. It has a unique character and charisma its Italian and German competitors can’t match. That said, some important media and safety-tech features are absent. So, it’s not perfect... just brilliant.

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.

Aston Martin DB1110/10
For a while there it looked like Aston Martin had fallen into the ‘everything looks the same’ trap, with Ian Callum’s breakthrough DB7 design in the mid-‘90s writing the script for the DB9 that followed, and heavily influencing everything else in the brand’s subsequent portfolio.
But in 2014, Aston’s design chief Marek Reichman sent a message with the DB10 Concept that things were about to change.
James Bond had Q and MI6 to thank for his DB10 company car in Spectre, but real-world Aston Martin customers were soon offered the DB11, which combined the muscularity of Reichman’s work on the ultra-exclusive One-77 from a decade earlier with the swooping, long-nosed proportions of his track-only Vulcan hypercar.
The hallmark of a well executed 2+2 GT is that it looks bigger in photos than it does in reality, and the DB11 is a perfect case in point.
Appearing limo-sized in our accompanying images, the DB11 is in fact 34mm shorter end-to-end than a Ford Mustang, but it’s exactly 34mm wider, and no less than 91mm lower in overall height.
And as any fashionista worth their salt will tell you, dark colours are slimming, and our ‘Onyx Black’ AMR, with gloss black 20-inch forged rims and black ‘Balmoral’ leather interior accentuated the car’s tightly drawn, shrink-wrapped surface treatment.
Signature elements in the shape of a broad, tapering grille, divided side vents, and sharply curved, two-level (smoked) tail-lights clearly identify the DB11 as an Aston Martin.
But the smooth integration of the car’s broad haunches (very One-77), gently tapering turret (optional exposed carbon) and flowing bonnet is masterful and fresh. The dash-to-axle ratio (the distance from the base of the windscreen to the front axle line) is Jaguar E-Type-esque.
And it’s all subtly aero-efficient, For example, the door handles fit flush to the body, the mirror housings double as mini ‘wings’, and the Aston Martin ‘Aeroblade’ system channels air running from carefully crafted openings at the base of the C-pillar, through the rear of the car to generate downforce (with minimal drag) across a lateral vent on the trailing edge of the bootlid. A small flap rises at “high speed” when more stability is required.
The interior is all business, with a simple instrument binnacle showcasing a central 12.0-inch digital speedo-within-tacho combination, flanked by configurable engine, performance and media read-outs on either side.
Aston has form with squared-off steering wheels and the DB11’s is flat on the bottom and decidedly straight on the sides, affording a clear view of the gauges without compromising purpose. A leather and Alcantara trim combination is (literally) a nice touch.
The teardrop-shaped centre stack sits in a slightly recessed section (optionally) lined with ‘carbon-fibre twill’, while the form and function of the 8.0-inch multimedia screen at the top will be immediately familiar to current Mercedes-Benz drivers, as the system, including the console mounted rotary controller and touchpad, is sourced from the three-pointed-star brand.
A band of proudly illuminated buttons across the centre includes gear settings for the transmission and a winged stop-starter in the middle. Strange, then, that the plastic knobs on the adjustable air vents look and feel so cheap and bland. This a $400k-plus Aston Martin, where’s the knurled alloy?
Other highlights include elegant sports seats trimmed in a combination of premium leather and Alcantara. Aston offers various levels of leather and our car’s black ‘Balmoral’ hide is taken from the top shelf.
The key accent colour inside and out on our test example was a screaming lime green, picking out the brake calipers, centre strips on the seats, and contrast stitching throughout the cabin. Sounds awful, looks amazing.
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.
Aston Martin DB117/10
On one hand it’s hard to describe a supercar like the DB11 as practical when its primary purpose is to go ridiculously fast and look incredibly good in the process.
But this is, in fact, a ‘2+2’ GT, meaning a couple of occasional seats have been squeezed behind the front pair to allow obliging contortionists, or more likely small children, to enjoy the ride.
No one is claiming full four-seat capacity, but it’s a trick that has for decades made cars like Porsche’s 911 a more practical choice for high-end, high-performance sports car buyers.
At 183cm I can verify the chronically limited space back there, without anything in terms of connectivity, specific ventilation or storage options provided. Good luck, kids.
For those up front it’s a very different story. First, the doors are hinged to move up slightly as they swing out, which makes entry and egress a more civilised process than it might otherwise be. That said, those doors are still long, so it pays to pre-plan a workable parking spot, and the high-mounted, forward-facing interior release handles are awkward to use.
Storage runs to a box between the seats, complete with a two-stage electrically controlled lid, housing a pair of cupholders, an oddments space, two USB inputs and an SD card slot. Then, there are slim pockets in the doors, and that’s about it. no glove box or netted pouches. Just a small tray for coins or the key in front of the media controller.
And speaking of the key, it’s another strangely underwhelming part of the DB11 AMR’s presentation. Plain and insubstantial, it looks and feels like the key to an under-$20k budget special, rather than the heavy, polished and glamorous item you’d expect to be subtly placing on the table in your preferred three-hat restaurant.
The carpet-lined boot measures 270 litres, which is enough for some small suitcases and a soft bag or two. In fact, Aston Martin offers a four-piece accessory luggage set “expertly tailored to match the car’s specification.”
Don’t bother looking for a spare wheel, an inflator/repair kit is your only option in the case of a puncture.
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.
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.
Price and features
Aston Martin DB118/10
Head into the $400k new car zone and expectations are understandably high. The DB11 AMR’s is a continent-crushing GT after all, and you want your fair share of luxury and convenience features to go with its huge performance potential.
For $428,000 (plus on-road costs), as well as the safety and performance tech (of which there’s plenty) covered in later sections, you can expect a lengthy standard features list, including a full-grain leather interior (seats, dash, doors, etc), Alcantara headlining, multi-function ‘Obsidian Black’ leather-trimmed steering wheel, electrically adjustable and heated front seats (with three memory positions), heated/folding exterior mirrors, front and rear parking sensors, and 360-degree ‘Surround View’ parking cameras (including front and rear cameras).
Also standard are cruise control (plus speed limiter), sat nav, dual-zone climate control, the electronic instrument cluster (with mode-specific displays), keyless entry and start, a multi-function trip computer, 400-Watt Aston Martin audio system (with smartphone and USB integration, DAB digital radio and Bluetooth streaming), plus the 8.0-inch touch-control multimedia screen.
Then there are LED headlights, tail-lights and DRLs, ‘dark’ grille, headlight bezels, and tailpipe finishers, 20-inch forged alloy rims, carbon-fibre bonnet vent blades and side strakes, dark anodised brake calipers and, to reinforce the car’s motorsport DNA, the AMR logo sits on the door sill plates and is embossed on the front-seat headrests.
Apple CarPlay and Android Auto functionality is a surprising omission, but our test car more than made up for it with a motherload of optional extras including an exposed carbon-fibre roof panel, roof strakes and rear-view mirror caps, as well as ventilated front seats, the vivid ‘AMR Lime’ brake calipers, plus a ‘Dark Chrome Jewellery Pack’ and ‘Q Satin Twill’ carbon-fibre trim inlays to add presence in the cabin. Along with some other bits and pieces this adds up to an as-tested total of $481,280 (before on-road costs).
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.
Engine & trans
Aston Martin DB119/10
The DB11 AMR’s (AE31) 5.2-litre, twin-turbo V12 is an all-alloy unit, tuned to deliver 470kW (up 22kW on the old model) at 6500rpm, while retaining the previous DB11’s 700Nm of maximum torque from 1500rpm all the way to 5000rpm.
As well as dual variable camshaft timing, the engine features a water-to-air intercooler and cylinder deactivation, which allows it to run as a V6 under light loads.
Drive goes to the rear wheels via a ZF-sourced eight-speed (torque converter) auto transaxle with column-mounted paddles, recalibrated for faster shifting in more aggressive Sport and Sport+ modes. A limited-slip differential is standard.
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'.
Aston Martin DB117/10
Minimum fuel requirement for the DB11 AMR is 95 RON premium unleaded and you’ll need 78 litres of it to fill the tank.
Claimed economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.4L/100km, the big V12 emitting 265g/km of CO2 in the process.
Despite standard stop-start and cylinder deactivation tech, in roughly 300km of city, suburban and freeway running we recorded a figure exactly nothing like that, according to the on-board computer we more than doubled the claimed number on ‘spirited’ drives. The best average figure we saw was still in the high teens.
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.
Aston Martin DB119/10
The moment you press the starter the DB11 begins a theatrical performance worthy of the Royal Shakespeare Company.
A high-pitched whine reminiscent of a Formula One air-starter precedes a raucous blast of exhaust noise as the twin-turbo V12 bursts into life.
It’s spine-tingling, but for those wanting to remain on good terms with their neighbours a quiet-start setting is available.
At this point, rocker buttons on either side of the steering wheel set the tone for what follows. The one on the left, marked with a shock-absorber graphic, allows you to scroll the adaptive damping set-up through Comfort, Sport, and Sport+ settings. Its ‘S’ branded partner on the right facilitates a similar trick with the drivetrain.
So, throwing urban serenity out the window, we pushed into maximum attack mode for the engine, and by extension the exhaust, selected D and began to enjoy the first act.
A launch-control function is standard, so purely in the interests of science we explored its function and can confirm it works exceptionally well.
Aston claims the DB11 AMR will accelerate from 0-100km/h in just 3.7sec, which is properly fast, and two tenths of a second faster than the standard DB11 it replaces.
Keep the pedal pinned and two things will happen; you’ll reach a maximum velocity of 334km/h and generate headline news across the country while making your way directly to jail.
With 700Nm available from just 1500rpm, and remaining on tap to 5000rpm, mid-range thrust is monumental and the thundering exhaust note accompanying it is the stuff automotive dreams are made of.
Peak power of 470kW (630hp) takes over at 6500rpm (with the rev ceiling sitting at 7000rpm) and delivery is impressively linear, without a hint of turbo hesitation.
The eight-speed auto is simply superb, picking up gears at just the right point and holding on to them for exactly the right amount of time. Select manual mode and the slender shift levers on either side of the steering column allow even more control.
In Sport and Sport+ drivetrain modes the howling exhaust is accompanied by an entertaining array of pops and bangs on up and down shifts. Bravo!
Spring and damper rates are unchanged from the previous DB11 and even on enthusiastic back-road runs we found suspension in Comfort and driveline in Sport+ to be the best combination. Flicking the shocks into Sport+ is best kept for track days.
Steering is (speed dependent) electrically power-assisted. It’s beautifully progressive, yet pin-sharp with excellent road feel.
The big 20-inch forged alloy rims are shod with high-performance Bridgestone Potenza S007 rubber (255/40 front – 295/35 rear), developed as original equipment for this car and Ferrari’s F12 Berlinetta.
They combine with the 1870kg DB11’s near perfect 51/49 front to rear weight distribution and standard LSD to deliver confidence-inspiring balance and ferocious power down on (quick) corner exit.
Braking is handled by huge (steel) ventilated rotors (400mm front – 360mm rear) clamped by six-piston calipers at the front and four-piston at the rear. We might have put them under decent pressure from time-to-time, but stopping power remained prodigious and the pedal firm.
In the calm of urban traffic the DB11 AMR is civilised, quiet (if you prefer) and comfortable. The sports seats can be adjusted to grip like a vice at speed or provide more breathing room around town, the ergonomics are spot-on, and despite its striking looks, all around vision is surprisingly good.
Overall, driving the DB11 AMR is a special event, flooding the senses and raising the heart rate no matter what the speed.
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.
Aston Martin DB117/10
Big speed demands serious active and passive safety, and the DB11 comes up short on the former.
Yes, there’s ABS, EBD, EBA, traction control, Dynamic Stability Control (DSC), Positive Torque Control (PTC) and Dynamic Torque Vectoring (DTV); even a tyre-pressure monitoring system, and the surround view cameras.
But if a crash is unavoidable there’s plenty of back-up in the form of dual-stage driver and passenger front airbags, front side (pelvis and thorax) airbags, as well as curtain and knee airbags.
Both rear-seat positions offer top tethers and ISOFIX anchors for baby-capsule and child-seat location.
The DB11 hasn’t been assessed for safety performance by ANCAP or EuroNCAP.
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.
Aston Martin DB117/10
Servicing is recommended every 12 months/16,000km, and an extended, transferable 12-month contract is available, including everything from provision of a taxi/accommodation in the event of breakdown, to coverage of the vehicle at “official Aston Martin organised events.”
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.
