The dirty dozen: V12 engines aren't dead yet
Is the 12-cylinder engine dead? When even Ferrari is downsizing V12 models like the GTC4Lusso to a twin-turbo V8, one can be forgiven for thinking that the 12-cylinder is a powerplant of the past.
And we fully understand that it’s awfully hard to justify a dozen pistons these days. For instance, a Mercedes-AMG S65 Coupe with a twin-turbo V12 has only 32 more kilowatts than the V8-powered S63, and it carries a US$71,000 premium ($A90,800). That’s more than US$1,165 ($A1,500) per additional kilowatt.
That, sir or madam, is the sound of life. The song of a living and breathing entity, the most soulful mechanical invention since the dawn of the Industrial Revolution. That is the melody of a dozen cylinders working in harmony, full of anima and heart and fury.
Even if it’s no longer the obvious choice (or even the most logical), the 12-cylinder lives. You’ll find it on at least eight luxury marques, from BMW to Mercedes and Rolls-Royce; Lamborghini to Aston Martin and Ferrari. (Bentley employs a W12 rather than the V configuration, but to great effect: Just see the new Continental Supersports.)
In the days of yore, a 12-cylinder engine was the only surefire way to guarantee power and refinement. They propelled the fighter planes of World War I and II, and motivated early automobiles from Sunbeam to Packard to Cadillac. The Ferrari V12 was — and is — considered a hallowed Italian treasure, at least equal to anything inside the walls of the Vatican.
In this era, a V12 is no longer a necessity. All those super- and turbochargers wrangle as much or even more power from smaller, more efficient engines which are lighter and less complicated.
This means that buying a car equipped with a V12 becomes a matter of choice. You opt in because — just like the best watches — you love the complications. The complexity of the machine connects you to a long and wonderful history, a bridge from one bygone era to today — a little bit of a Supermarine Spitfire fighter lives on in your garage.
It is akin to buying an automobile with a manual transmission. An automatic may be the saner choice, but it isn’t nearly as soulful. And so we reserve a special call-out to Aston Martin, which offered a 2017 Vantage S model with both a V12 and a manual. (The manual was a dogleg, no less.)
Aston Martin is one of those dear brands that continues to protect and develop the engine. At a recent launch of the new V8-powered DB11, chief executive officer Andy Palmer acknowledged that the smaller engine, a twin-turbo unit sourced from AMG, would be the volume model. However, he also said that the future of Aston Martin’s self-developed powerplants would be twofold: all-electric motors and gasoline-powered V12 engines. “The V12 is simply part of who we are,” he affirmed.
Try to explain the magic of a V12 to a novice, and you may talk about the limitless torque, the ability to rev into the stratosphere, and the smooth delivery of power. But soon enough you’ll turn to the sound, the defining element which simply can’t be recreated by a trick turbo. While each car model has its own personality, they share a glorious commonality. The smooth, basso profundo rumble at the start is followed by a rise in pitch and decibels as you coax the revs higher and higher. At full tilt, a V12 produces a howl so sharp that it could cut meat from bone. And with a wide open throttle, a roaring V12 resonates throughout the entire frame of a vehicle. It’s all around you — even your sternum vibrates like a tuning fork.
I’ve driven hundreds of sports cars in my career, and yet I can still remember most of my V12s. The Lamborghini Miura through southern Italy; the Aston Martin DB9 from San Francisco to Monterey. The Ferrari 612 Scaglietti certainly wasn’t the most beloved of the V12s, but it was my first front-engine Ferrari, and therefore memorable indeed.
And, not so long ago, that US$247,000 ($A315,800) Mercedes-AMG S65 Coupe. I was in the New Mexican desert, late at night, tearing down a lonely road under a star-speckled night sky. The 6-litre, twin-turbo V12 was at full cry, and I had every window open so I could best experience it.
With the throttle pinned, the engine sent a thrum through the entire car. Clean desert air mixed in with the soundtrack and it was irrepressible, exultant… magical. The 12-cylinder lives.
