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 unveils 202-mph Continental GT Speed Convertible

That purple haze all in your eyes is the 2013 Bentley GT Speed Convertible. The cynical view is, "Bah, take a GT Speed and cut the top off. There. Pass the salt, please...". But when you're Bentley, more than 90 years old, and charging these kinds of ducats, there's no reason to take the cynic's shortcut. So of course the GT Speed Convertible gets all of the Speed-family accoutrements: matrix radiator grille hiding a twin-turbocharged, 6.0-liter W12 with 616 horsepower and 590 pound-feet of torque, eight-speed ZF transmission enabling 15 percent better fuel economy, beefier lowered suspension, larger rifled exhaust tips, inlet manifold finished in black crackle and a Mulliner Driving Specification cabin.
Among the many refinements added to the convertible, though, are neck warmers in the seats, the 21-inch wheels unique to this car, class-leading stiffness - admittedly, it's a very small class, but its torsional rigidity of 22,500 Nm/degree is only 500 Nm below that of the Lamborghini Gallardo coupe. The stiffening required to achieve that number will undoubtedly have something to do with the 485-pound weight gain over the GT Speed Coupe.
Still, when the GT Speed Convertible weighs 5,500 pounds, what's a few hundred between friends? More importantly, the weight doesn't scuttle performance: 0-60 comes in 4.1 seconds, a tenth shy of the coupe. The gap stretches as you approach The Ton, the GT Speed Convertible needing just 9.7 seconds to get there, the coupe just nine seconds. Trust us, though, everyone will be too busy blasting along to notice. Everyone will want to pack light, however, because the Speed Convertible loses 3.5 cubic feet of trunk space. It remains the fastest four-seat convertible in the world with a 202-mph top speed.

Bentley Grand Convertible is grand, is a convertible

What you see above is the Bentley Grand Convertible, live from the Los Angeles Auto Show. It's basically a droptop version of the Mulsanne Speed, which would seem to be a foregone conclusion for production, but apparently isn't, according to Bentley Chairman and CEO, Wolfgang Dürheimer.
"We are eagerly awaiting the response of our customers to this car. We will ensure that this car - if it reaches the roads - will be a highly exclusive, extremely limited collector's piece."
With its production possibilities out of the way, and with the image gallery you see above proving that it is, indeed, a convertible, we can move on to what makes this Grand Convertible so grand. Equipped with the same 6.75-liter engine with 530 horsepower and 811 pound-feet of torque as its hardtop brethren, it certainly won't be lacking for power. The Grand Convertible has been "fashioned entirely by hand from the very finest materials," says Bentley, and the tonneau is made from the largest piece of wood veneer ever applied by the automaker.
