40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Bentley builds its final 6.75-liter V8, ending a 61-year production run

Bentley has just finished its very last 6.75-liter V8. While engines come and go, this is significant because Bentley has been building this engine, known as the L-series, for 61 years. This final engine will go in the 30th and last Bentley Mulsanne, a 6.75 Edition by Mulliner, marking the end of the flagship sedan. The L-series engine was first introduced in 1959, and according to Bentley, it was developed in order to develop more power than its existing inline-six without adding weight or taking up more space. The engine in fact weighed 30 pounds less than the six-cylinder, and it made about 180 horsepower. That original engine "only" had 6.2-liters of displacement, and it wasn't until 1971 that it would reach 6.75 liters thanks to increased stroke. This final version of the engine is significantly different from its fuel injection to its twin-turbochargers, but is based on the same design. And with 530 horsepower and 811 pound-feet of torque, it's the most powerful iteration of the engine. At 61 years, the Bentley engine is arguably the V8 with the longest production run. While the first-generation Chevy small block V8 was introduced earlier for the 1955 model year and is still built in crate engine form, GM stopped using it in production cars in 2002. Far fewer Bentley engines were built, though, with a total over 36,000, as opposed to the millions of Chevy small blocks in the world. Of course, volume is sort of the antithesis of what makes a Bentley a Bentley. With the 6.75-liter engine out of production, all of Bentley's engines are derived from VW Group engines, from its W12 to the plug-in hybrid V6. Related Video:    

Bentley re-creates one-of-a-kind sports sedan destroyed in 1939

Bentley's Mulliner division specializes in making one-off (or few-off) projects for clients willing to foot the bill. They're the folks you'd want to talk to if you want a long-wheelbase Flying Spur, a Bentayga-based dually pickup, or anything in between. The division only works on new models, but it stepped outside of its comfort zone to re-create a one-of-a-kind Bentley manufactured and destroyed in 1939. The project is part of Bentley's on-going centennial celebration, and finishing it in time was easier said than done. It made building a concept car like the EXP 100 GT look like assembling a Lego kit. The original Corniche disappeared after getting bombed by the German army, and a majority of the people who saw it in person are dead, so the men and women tasked with resurrecting it only had a handful of period, black-and-white photographs and technical drawings to work with. The final product looks stunning, and Bentley claims it's identical to the original in every way. Parts like the chromed headlight bezels, the droplet-shaped fenders, and the wooden dashboard were exclusive to the Corniche, so they had to be manufactured from scratch using the correct materials, and the right production techniques. The British firm could have saved itself the trouble of re-creating this unique part of its history if another car hadn't pulled out in front of it 80 years ago. Bentley made the original Corniche during tumultuous times as it explored the possibility of releasing a more powerful variant of the Mark V scheduled to make its debut in October 1939. It asked French designer Georges Paulin to draw a futuristic, streamlined body, and it commissioned Paris-based coachbuilder Carrosserie Vanvooren to build it using thinner-than-normal steel to save weight. The Corniche lapped the Brooklands track for the first time in May 1939 and quickly reached over 100 mph, an impressive speed at the time. Testing continued in rural France, where the big Bentley blended in as well as a flying saucer. In August 1939, one of the company's test drivers swerved to avoid another car, rolled, and wrapped the aerodynamic front end around an unsuspecting tree. Bentley separated the body and the chassis. It immediately shipped the chassis to its headquarters in Crewe, England, and curiously asked a local shop to repair the body instead of sending it back to Vanvooren in Paris.
