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.

2020 Bentley Bentayga Hybrid is less efficient on the highway than V8 version

Official EPA fuel-economy ratings are out for the 2020 Bentley Bentayga Hybrid, the luxury brand’s first electrified offering, and they donÂ’t exactly bathe the crossover in a green light. As spotted by Green Car Reports, the plug-in performs worse on the highway than its V8-powered combustion sibling. The EPA rated the Bentayga Hybrid as delivering 18 miles in all-electric range, which is two miles more than Bentley previously touted, and a combined 19 miles per gallon in hybrid mode, which is indeed the most efficient of the three Bentayga versions offered. ItÂ’s rated at 17 mpg city and 21 on the highway. By contrast, the 4.0-liter twin-turbo V8 version of the luxury crossover offers just 17 mpg combined, yet it delivers 23 mpg on the highway. Its overall EPA-rated highway range also beats the Hybrid, at 518 miles to 430 miles on a full charge and tank. The Bentayga Hybrid combines a turbocharged 3.0-liter V6 and a 94 kilowatt electric motor that also functions as a generator. The system combines for 443 horsepower and 516 pound-feet of torque, with a 5.2-second 0-60 mph time. It sends that through an eight-speed automatic transmission driving all four wheels. Curb weight is a hefty 5,709 pounds. Base price starts at $160,000. The V8, by comparison makes 542 hp, nearly 100 more ponies, and 568 lb-ft, with a 0-60 mph of 4.4 seconds. It will set you back $171,025. At any rate, both versions are well below the 27 combined mpg of the average 2020 vehicle, according to the EPA. The HybridÂ’s fuel economy ratings suggest that buyers may be motivated less by concerns about carbon footprint than conveying the appearance of having those concerns. Bentley has said its first full electric vehicle will be a dedicated model that will arrive in 2025 at the earliest, and possibly with a solid-state battery pack. Related Video:

Bentley to retire aging 6.75-liter V8 with current Mulsanne

The massive 6.75-liter V8 in the Bentley Mulsanne is one of the oldest engines still in production. But it may not be around for much longer. According to Car and Driver, Bentley intends to finally put the big old pushrod V8 to pasture once the current Mulsanne is phased out, thus putting an end to a saga that goes back some 57 years. Powerful as it may be, ever-stricter exhaust emissions and fuel-consumption regulations will see that the L Series V8, originally introduced way back in 1957, doesn't stay in production forever. Whenever the Mulsanne is replaced, it will reportedly get a brand-new twelve-cylinder engine. Bentley is currently the world's largest producer of dozen-pot powerplants. Production of the British automaker's 6.0-liter twin-turbo W12 far outpaces anything from Rolls-Royce, Mercedes-Benz, BMW, Ferrari, or Lamborghini. Over the decades since its introduction, Bentley's long-serving V8 has gone from making an "adequate" amount of power and torque to an impressive 530 horsepower and a positively massive 811 pound-feet (with the help of a couple of turbochargers). Its eventual discontinuation wouldn't be the first attempt on the life of the 6.75-liter engine. When BMW briefly took control of both Rolls and Bentley, it replaced the big engine by a smaller 4.4-liter V8. Customer demand led Bentley to bring the old engine back. It will likely be some time before we get details of Bentley's next powerplant. Models like the Mulsanne and Rolls-Royce Phantom tend to stick around for a long time, and the latest version of Bentley's flagship was just released earlier this year. Related Video:
