Aston Martin DB12: The Super Tourer Era

When Aston Martin set out to replace the DB11, they faced a difficult decision. The DB11 was a beautiful and capable Grand Tourer, but it was often criticized for its aging infotainment system and for being slightly too soft dynamically compared to rivals from Ferrari and Porsche.

Aston Martin didn’t just want to update the DB11; they wanted to elevate the entire category. Upon its unveiling in 2023 (coinciding with the brand’s 110th anniversary), Aston Martin declared the DB12 to be the world’s first “Super Tourer.”

This wasn’t just marketing hyperbole. The DB12 represents a massive leap forward in handling precision, technological integration, and sheer, brute-force performance, fundamentally altering the trajectory of the legendary “DB” bloodline.

Historical Context: The DB Lineage

The “DB” designation in Aston Martin nomenclature stands for David Brown, the industrialist who purchased the company in 1947 and steered it through its golden era — the DB4, DB5, and DB6 that defined British automotive glamour in the 1960s. The name was retired briefly after Brown sold the company in 1972, but it was revived with the DB7 in 1994 and has remained the cornerstone of Aston Martin’s range ever since.

Each generation of the DB has marked a significant chapter in the brand’s history. The DB7 relaunched the brand after years of near-obscurity. The DB9 established Aston Martin as a serious luxury rival to Ferrari and Bentley. The DB11 proved the brand could build modern technology and still retain its soul. The DB12 had to take the next step: combining supercar performance with genuine daily usability and a technology suite worthy of its price tag.

Announced during Aston Martin’s 110th anniversary celebrations in 2023, the DB12 arrives at a critical inflection point. The luxury GT market has never been more competitive, and Aston Martin’s new executive team — led by Lawrence Stroll and CEO Amedeo Felisa — made clear that merely good was no longer sufficient. The DB12 had to be exceptional by any measure.

The Powertrain: Farewell to the V12

The most controversial decision surrounding the DB12 was the engine. For the first time in a flagship DB model since the DB7, there is no V12 option.

Instead, Aston Martin went all-in on their partnership with Mercedes-AMG. The DB12 is powered exclusively by a heavily modified version of the AMG 4.0-liter twin-turbocharged V8.

However, this is not a standard AMG engine dropped into an Aston chassis. Aston Martin engineers significantly reworked the engine, fitting larger turbochargers, redesigned cam profiles, optimized compression ratios, and a completely overhauled cooling system (adding two additional auxiliary coolers to the central main radiator).

The result is a staggering 680 PS (671 bhp) at 6,000 rpm and 800 Nm (590 lb-ft) of torque available from 2,750 to 6,000 rpm. This is a 34% increase in power over the outgoing DB11 V8, and it actually produces more horsepower and significantly more torque than the old 5.2-liter twin-turbo V12.

Power is routed through an 8-speed ZF automatic transmission, but crucially, for the first time on a DB model, it features an Electronic Rear Differential (E-Diff) linked directly to the car’s dynamic stability control system. This allows the DB12 to transition from fully open to 100% locked in milliseconds, drastically improving agility on tight roads.

Why the V8 Makes Sense

The decision to drop the V12 was commercially rational and dynamically justified, even if it stirred genuine debate among enthusiasts. The 5.2-liter twin-turbo V12 is a remarkable piece of engineering, but it is also heavy, expensive to manufacture and maintain, and increasingly difficult to homologate globally against tightening emissions standards. The V8, despite having half the cylinder count, produces more power in DB12 tune and does so from a significantly lighter package — approximately 115 kg less sits over the front axle, transforming the car’s handling balance and agility.

The V12 lives on in the DBS and in bespoke special editions like the Valour, keeping the flame alive for those who simply must have twelve cylinders. For the DB12’s role as a daily-driveable super tourer, the argument for the lighter, more efficient V8 is compelling.

A Sharpened Chassis

To justify the “Super Tourer” moniker, the chassis of the DB12 had to be significantly stiffer and more responsive than the DB11.

The bonded aluminum structure was reinforced, resulting in a 7% increase in global torsional rigidity (with specific areas like the front cross-brace and rear bulkhead seeing much higher increases).

The suspension features next-generation intelligent adaptive dampers, which offer a 500% increase in the bandwidth of force distribution compared to the previous generation. This means the car can be incredibly soft and compliant in “GT” mode, but instantly transform into a stiff, roll-resistant sports car in “Sport+” mode.

To manage the 680 horsepower, the DB12 is the first production car in the world to be fitted with the new Michelin Pilot Sport 5 S tires as standard, featuring a bespoke compound explicitly developed for Aston Martin (marked with “AML” on the sidewall).

The E-Diff: A Fundamental Shift

The introduction of the electronic rear differential deserves particular emphasis because it represents a genuine step change in how the DB12 behaves dynamically versus any previous DB model. A conventional open differential sends torque to whichever rear wheel has the least traction — the worst possible outcome when you’re pushing hard through a corner. A mechanical limited-slip differential helps but responds passively to wheelspin.

The E-Diff in the DB12 responds predictively. Linked to the car’s stability management system, steering inputs, throttle position, and lateral acceleration sensors, it can lock up partially or fully before wheelspin even occurs. The result is a car that rotates sharply and obediently into bends, then grips tenaciously and drives cleanly out of them — a quality that the DB11, for all its virtues, never possessed.

Design: Aggressive Elegance

Visually, the DB12 is an evolution of the DB11, but its stance is far more aggressive.

The track has been widened (6 mm at the front, 22 mm at the rear), giving the car a more muscular, planted footprint. The front fascia is dominated by a massive, reshaped Aston Martin grille (necessary for cooling the upgraded V8) and new LED headlights featuring a distinct, segmented daytime running light signature. The iconic Aston Martin wings badge was also redesigned for the DB12.

The car sits on massive 21-inch forged alloy wheels, which, despite being larger, are actually 8 kg lighter than the 20-inch wheels on the DB11, reducing unsprung mass.

The Volante (convertible) version of the DB12 retains the structural integrity of the aluminum tub through an extensive system of supplementary stiffening. The electrically operated fabric roof stows neatly beneath a hard tonneau cover and opens or closes in under 14 seconds.

The Digital Revolution: An In-House Interior

The biggest transformation, and the most necessary one, occurred inside the cabin. The DB11 utilized an outdated, reskinned version of Mercedes-Benz’s old COMAND infotainment system, which severely let down the luxury experience.

For the DB12, Aston Martin finally developed their own, completely bespoke infotainment system entirely in-house.

The centerpiece is a crisp, highly responsive 10.25-inch touchscreen integrated beautifully into the sloping center console. Crucially, Aston Martin did not succumb to the trend of putting every function on a screen. They retained beautiful, tactile, knurled metal physical buttons and rollers for the climate control, exhaust valves, suspension settings, and volume.

The cabin is swathed in hand-stitched Bridge of Weir leather, Alcantara, and carbon fiber. It represents a monumental leap in material quality and technological usability, finally offering an interior that matches the car’s exterior beauty and price tag.

Build Quality and Personalization

One area where Aston Martin has made substantial strides with the DB12 is overall build quality. Early DB11 examples were criticized for some interior panel fits that did not match the car’s price point. The DB12 addressed this through revised assembly processes and stricter quality gates at Gaydon.

The “Q by Aston Martin” personalization service offers DB12 buyers essentially unlimited customization options — from bespoke body colors mixed to a customer’s specification to unique interior materials, custom embroidery, and special badging. Some buyers have chosen to match their DB12’s color to significant personal items or to colors that reference classic Aston Martins from the 1960s, resulting in genuinely one-of-a-kind examples.

Rivals and the Competitive Landscape

The DB12 operates in a market segment that includes the Ferrari Roma, the Bentley Continental GT, and the Porsche 911 Turbo S — each a brilliant and distinctive proposition. The Ferrari Roma emphasizes mid-engine purity and Italian visual drama. The Continental GT prioritizes extreme refinement and four-seat practicality. The 911 Turbo S offers near-supercar performance in a daily-use package.

The DB12’s answer to each of these is the combination of authentic British character, genuine supercar performance numbers, and a level of aesthetic elegance that none of its rivals quite matches. It is not the most technologically complex car in its segment, nor the most practical. But it may well be the most desirable — which has always been the point of an Aston Martin.

The Future of Aston Martin

The Aston Martin DB12 successfully bridges the gap between continent-crushing Grand Tourers and razor-sharp supercars. By utilizing the lighter V8 engine, stiffening the chassis, and introducing the E-Diff, the DB12 handles with a precision that the DB11 could only dream of, without sacrificing the ride comfort required of an Aston Martin.

The DB12 also marks a confident step in Aston Martin’s ongoing transformation under new ownership. Lawrence Stroll’s considerable investment has provided the resources to invest in a genuinely in-house infotainment system, improved build quality, and the kind of comprehensive chassis development that produces a truly well-rounded car. It is a triumphant statement of intent for the brand’s future and a worthy successor to one of automotive history’s most celebrated nameplates.
