Aston Martin Aims to Keep V12 Engine in the Mix

Aston Martin is working on a replacement for the twelve-cylinder DBS model, while Jeep is recalling over 30,000 plug-in hybrid Wrangler units in the United States.

This is AM Drive, Motor1’s daily rundown of essential news before you hit the road.

Aston Martin Committed to Preserving the V12 Engine

In the era of downsizing, Aston Martin is choosing to stand out. Despite the release of the DBS 770 Ultimate this year, suggesting the V12 engine’s eventual retirement, it appears that the twelve-cylinder powerplant will remain in use. According to a recent report from Autocar, the replacement for the DBS will retain the V12 as it transitions from being a grand tourer to a full-fledged supercar.

Marek Reichman, Aston Martin’s chief creative officer, shared with the British publication that the DBS successor will be a “completely different” vehicle. While it’s premature to discuss specifics, it’s worth noting that the 770 Ultimate Coupe and Volante models were equipped with a twin-turbo 5.2-liter engine generating 759 hp and 664 lb-ft of torque.

The new DBS won’t be the only player in the V12 supercar category, as the replacement for the Ferrari 812 Superfast is also expected to retain its twelve cylinders. In May 2021, Ferrari stated that its naturally aspirated 6.5-liter V12 engine would receive an upgrade beyond the 830 horsepower offered by the 812 Competizione.

Abandoned Dump Truck Fires Up Two-Stroke V12 Diesel After Many Years

We usually associate twelve-cylinder engines with high-end cars and the occasional SUV like the Audi Q7 V12 TDI, Rolls-Royce Cullinan, or the Bentley Bentayga. However, these powerful engines have a long history of serving a utilitarian purpose at work sites, such as the Detroit Diesel Series 71, a two-stroke engine available in both inline and V configurations.

Left to rot for many years, a rusty abandoned dump truck features the V12 variant with a 14-liter displacement and about 425 horsepower. The 12V-71 was offered with varying outputs between 394 hp to 525 hp. A nearly hour-long video showcases the revival of this massive 852-cubic-inch engine, which at one time hauled heavy loads at a quarry in Queensland, Australia. The dump truck, sadly, was left for dead to make way for newer, more advanced big rigs.

The Detroit Diesel Series 71 used a gear-driven Roots blower, though it was technically called a naturally aspirated engine by the Society of Automotive Engineers (SAE). After being dormant and exposed to the elements, the dump truck had a rust hole in the intake. With the addition of fresh diesel, a fuel injector cleaner, and WD-40, along with the installation of a pair of batteries, the V12 engine roars again in the video.

If you want to jump to the best part of the video, that V12 roars again from the 54:20 mark.
