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:    

Top 10 small cars with the longest total driving range

Editor's Note: Since this article was originally posted in the spring of 2015, much has changed in the automotive landscape, especially among those shopping for small car economy. With thanks to Volkswagen for their blatant cheating – and subsequent cover-up – on diesel emissions, the largest player in the diesel passenger car segment isn't playing – they're paying; billions are going for both car buybacks and federally-imposed penalties. And for a few VW execs there exists the very real possibility of jail. With the absence of a big player and the abrupt entrance – via Chevy's new Bolt – of an affordable EV with 200+ miles of range, we've limited the diesel listings to Jaguar's new XE. And for those wanting an updated look at efficiency and range, Autoblog has it – or the EPA has it. Long before electric vehicles were part of the mainstream conversation, car lovers and skinflints alike would boast about the total range of their vehicles. There's something about getting farther down the road on one tank of gas that inflames the competitive spirit, almost as much as horsepower output or top speed. Of course, the vehicles with the very best range on today's market are almost all big trucks and SUVs; virtually all have the ability to carry massive reserves of fuel. Top up a standard Chevy Suburban and you can expect to travel almost 700 miles (you'll need to stop before the Suburban stops...), while a diesel-fed Jeep Grand Cherokee manages almost as many. But what about vehicles that are smaller? The EPA has, essentially, three classifications for 'small' vehicles: Minicompact, Subcompact and Compact. All three are measured based on interior volume, meaning that some cars with rather large exterior dimensions and engines slot in next to traditional small cars. But even though impressive GT coupes from Porsche, Bentley and Mercedes-Benz may have much larger gas tanks to feed their powerful engines, that capacity is offset by higher rates of consumption... in most cases. We used the EPA's Fuel Economy Guide for model year 2017 cars as a start, calculating the official highway miles per gallon rating with each vehicle's tank capacity. The resulting numbers aren't necessarily real world, but they do offer a spectrum for total theoretical range. The eventual top ten surprised me on a few occasions, and comprised quite a varied list of vehicles. 10.

Bentley will build 1929 Team Blower continuation series of 12 cars

Bentley considers Sir Tim Birkin’s supercharged 4 1/2 -liter Team Blower race car to be the company's "most revered heritage car" ever. So revered, in fact, that Bentley wants to make the car again, 12 times over. With the help of some reverse engineering by Mulliner, Bentley has announced its intentions for an extremely special continuation series limited to only a dozen examples built nearly identical to the original.  Through various methods, Bentley has been celebrating its heritage all throughout 2019, the centenary of the brand's founding. Just in the summer months, Bentley released the third-gen Flying Spur, unveiled the EXP 100 GT autonomous electric concept, built a Continental GT convertible that honors the 1929 Blower Number 1, won Best of Show at the Pebble Beach Concours, and re-created 1939 Corniche sedan with the help of Mulliner. That last achievement is particularly relevant, as Mulliner typically crafts bespoke new cars, as opposed to building old ones. After successfully bringing the Corniche into the 21st century, however, Bentley is confident Mulliner can take on the complex task of rebuilding the legendary Team Blower.  Bentley claims this will be the world's first continuation of a pre-war race car, and the original production run didn't even make it to double digits. Only four Team Blowers were built for Birkin and the boys to race, which they did at Le Mans and all over Europe. Bentley is building 12 re-creations because that's how many races the original cars competed in. In order to take this project on, Bentley will disassemble Team Blower chassis No. HB 3404 down to its nuts and bolts. The parts will all be cataloged and 3D scanning of each individual piece will create the foundation for the new cars. Bentley will then combine use of the original 1920s molds and tooling jigs with modern manufacturing methods to create 12 identical sets of parts. The new cars will be as close to identical to the original car as possible, but current safety regulations will force Bentley to make a few changes and alterations. Under the hood, the Continuation Series cars will have 16-valve four-cylinder engines with aluminum crankcases, cast-iron cylinder liners, and non-detachable cast-iron cylinder heads. With the help of Amherst Villiers Mk IV roots-type supercharger replicas, the 4,398 cc engines will be rated at 240 bhp at 4,200 rpm.
