Bentley Continental GT 'Ultratank' makes tracks in Russia. Literally

When the automotive news cycle last turned its attention to Russia, it was to celebrate the maniacs who'd linked three cheap four-cylinder engines to create a 12-cylinder Lada. Our newest visit to the motherland is for the diametric opposite: a first-generation Bentley Continental GT placed on a custom set of heavy duty tracks. Created by Russian YouTube channel AcademeG, the navy blue mutant is called the Ultratank, and its waiting for its close-up in the Akira sequel. Chronicling the build began last August, sometime after AcademeG's presenter bought the cheapest Continental GT he could find. Seems that kind of purchase is a cautionary tale in Russia as much as it is here, because the Bentley's 6.0-liter, twin-turbo W12 needed a list of expensive repairs, starting with new turbos. It appears that was the cue to throw out the whole engine, drivetrain, and frame. AcademeG took the coupe to Swap-Point, who replaced the stock motor with Toyota's Japanese-market 4.3-liter V8 used in the Toyota Crown Majesta, Celsior, and Soarer and Lexus GS, LS, and SC 430. The engine sends power to a solid rear axle only through a torque converter automatic. From there, the twist is transferred to a set of heavy vehicle tracks measuring 98.4 inches long. The Bentley's passenger tub and upper portions mostly survived the transformation, but tube-frame construction replaced the stock architecture front and rear. Nine months later, the Ultratank has taken its first steps. The Russians took their baby into the woods to play, and - watched by some goats and shepherds - proved they got it mostly right in spite of a few issues. Running on treads is often done best in low revs, but the engine doesn't like low revs. There wasn't enough tension on the tracks, and the rubber nubs aligning the tracks with the wheels aren't substantial enough, so the tracks rolled off the wheels during hard cornering. And there are no brakes. Slowing down requires sawing at the wheel, which brakes the inside tread as the Ultratank starts to turn. Even so, the vehicle and the test were declared a success. The team will tune the engine, add doors and tweak the tracks, but according to YouTube's Russian translation, "everything is simply ideal." You can check out the entire build while awaiting updates on the next big changes, including a higher top speed: The Ultratank tops out at 31 miles per hour now, and AcademeG wants to double that.

Bentley W12 engine production will officially end in April 2024

We knew the Bentley W12 engine had an expiration date before, but it’s going to come up even quicker than expected. Revealed today, Bentley says the last W12 engine it produces will be in April 2024. ThatÂ’s only one year and a couple of months away! Previously, Bentley made it clear that it would only sell PHEVs and EVs by 2026, implying the W12 was done for. It wonÂ’t last long enough to bump into that 2026 limit now that the 2024 production end is set. By the time its end date rolls around, Bentley will have made over 105,000 W12 engines since the 6.0-liter twin-turbocharged unit was introduced for 2003. Each of those engines was hand-built by a team of craftspeople — Bentley says each engine takes approximately 6.5 hours to complete. Which Bentley models are going to be made available with these final W12s, you ask? The real celebration for Bentley is happening with the Batur, a small run of Mulliner coach-built coupes based on the Continental GT. Final validation just wrapped up for the Batur version of the W12, and itÂ’s the most powerful yet at 740 horsepower and 737 pound-feet of torque. Versus the W12 found in other Bentley models, the Batur features reworked intake, exhaust and cooling systems along with a revised engine calibration. Unfortunately, all 18 Baturs (pic below) are already spoken for. If you still want a W12, Bentley says it has limited order slots left for the Continental GT Speed, Bentayga Speed and Flying Spur Speed. Additionally, Bentley will allow you to spec it in either the Continental GT Mulliner or Flying Spur Mulliner. No other new Bentley orders will be W12-compatible between now and production completion. The company warns that there are only a limited number of build slots left, so anyone still on the fence should act quickly if they want the W12.  Over the years, Bentley says the W12 has seen a 37% increase in power, 54% increase in torque and 25% reduction in emissions. The biggest changes came in 2015 when Bentley redesigned the engine “from the sump up” for the launch of the Bentayga SUV. As of today, there are 30 people involved in the engine assembly process. Bentley says it aims to retrain and redeploy all 30 into different positions once W12 production ceases Related video: 2024 Maserati GranTurismo walkaround

Bentley's Ultra Performance Hybrid succeeds the 6.0-liter W12

The twin-turbo 6.0-liter W12 engine composed the soundtrack to dreams around the world once it found a home in the Bentley Continental GT, which entered a production in 2003. That engine will sing its final encore in the Bentley Batur Convertible before the curtain comes down, tuned to its highest-ever output of 739 horsepower and 738 pound-feet of torque. The Englanders in Crewe have lifted the hood on the successor, without providing all the details. What we know for now is that the powerplant debuting this summer is called the Ultra Performance Hybrid, a V8 PHEV with "more than 750 PS combined output" and an all-electric range of 50 miles on the WLTP cycle.   We haven't been given a displacement figure, nor did Bentley use the word "turbo" in its release. However, looking around the Volkswagen Group, the twin-turbo 4.0-liter V8 PHEV in the Porsche Panamera Turbo E-Hybrid and Lamborghini Urus SE seems a solid fit for this application. We're told to expect "the highest output ever offered in a Bentley," Since the 740 hp in the droptop Batur equals 750 PS — achieved without electrical assistance — there's reason to hope for something closer to 800 hp than 750. The Panamera Turbo E-Hybrid makes a combined 670 hp and 680 lb-ft, the Urus SE a combined 800 hp and 699 lb-ft. Both of them also hide a 25.9-kWh battery.

The company released a short sound clip, and yep, this things sounds like a Bentley engine, from purr to growl never leaving the basso profondo range. The Ultra Performance Hybrid will take its place at the top of the Bentayga, Continental GT, and Flying Spur ranges before the summer ends. We find out closer to that time what happens to the other engines on the menu, the twin-turbo 4.0-liter non-hybrid V8 and the twin-turbocharged 2.9-liter and 3.0-liter V6 plug-in hybrids for the Flying Spur and Bentayga, respectively.
