It's often a sad occasion when a modern car ends up being the last example of a piece of old-school engineering. They could be the last car to use a certain engine. They could also be the last car to use a certain layout. They could even be the final breath of a now-discontinued model.These cars come from all over the spectrum, from sports cars to luxury cars. A couple of them are also limited-edition versions that celebrate them being the end of an era. What they all share is that status of being the end of the line of old-school engineering for their brands. Bentley Mulsanne 6.75 Edition By Mulliner BentleyFor many decades, the Bentley L-Series V8 was one of the best engines you could get in a luxury car. It was a low-revving, torquey unit that gave great performance to the incredibly comfortable cars made by Bentley (and Rolls-Royce, while both companies were owned by the same parent company). It was the height of old-school luxury engineering. That's why it was a bit of a sad event when the Bentley Mulsanne 6.75 Edition by Mulliner was announced as the final car to ever use this engine, and the final Mulsanne ever. Based on the Mulsanne Speed, the 6.75 Edition by Mulliner's twin-turbo V8 has 530 horsepower and an astonishing 811 pound-feet of torque. That's enough to take this huge, heavy limousine from 0-60 mph in less than 5 seconds, and onto a top speed of 190 mph.Only 30 examples of the Mulsanne 6.75 Edition by Mulliner were ever made. Out of those 30, only 6 were made for the United States. This makes it one of the rarest production Bentleys ever made, as well as the final example of an old-school luxury Bentley. BMW M3 (E92) BMWWhenever anyone talks about the BMW M3, the E92 version is mentioned as one of the best. There are plenty of good reasons why people would think that. Not only was it the final M3 coupe before the coupe and convertible versions switched over to being M4s, but it was also the final M3 to have a naturally-aspirated engine. That engine was either a 4.0-liter V8 in the more standard models, or a 4.4-liter V8 in the M3 GTS. This was a seriously powerful unit, producing up to 444 horsepower in the GTS's 4.4-liter version. Like any naturally-aspirated V8, it also sounded fantastic! BMW M760i xDrive Final V12 For a long time, the top model of BMW's most luxurious car had a V12 engine. Those V12-powered versions of the 7-series were often very underrated compared to the Audis and Mercedes they competed against. Now, sadly, the V12 BMW is no more in any form. The final BMW to ever get a V12 was the M760i xDrive Final V12. This car used the 6.6-liter twin-turbocharged V12 that powered the regular V12-powered 7-series model at the time. This was an absolute beast of an engine, producing 601 horsepower and 627 pound-feet of torque. Thanks to the huge traction from that xDrive all-wheel drive system, this beast can accelerate from 0-60 mph in just 3.6 seconds. That's enough to genuinely worry some supercars in a straight line!Like the Bentley Mulsanne 6.75 Edition by Mulliner, the BMW M760i xDrive Final V12 was only produced in tiny numbers. Only 12 examples were ever made, and they were all allocated to the US market. If you ever manage to see any of these, you're seeing one of the rarest BMWs ever made as well as a final example of old-school BMW luxury. Chevrolet Corvette (C7) Via: Bring a TrailerIn the lineage of the Chevrolet Corvette, the C7 is an incredibly important generation. It was the final 'traditional' Corvette, as the C8 switched to a mid-engined, rear-wheel drive layout. It was also the final Corvette generation to be available with a manual transmission - the C8 has only ever been available with an 8-speed automatic. The most special of the C7 variants has to be the 2019-only ZR1, which produced 755 horsepower from its supercharged V8. That makes it the most powerful front-engined Corvette ever made, and a legitimate challenger to the supercars of its era! Ferrari F8 Tributo Via: FerrariOut of the various mid-engined V8 Ferraris over the years, the F8 Tributo really doesn't get talked about a lot. That's very odd, considering it's the final non-hybrid mid-engined V8 Ferrari ever made. It has the ultimate evolution of Ferrari's twin-turbo V8, producing 710 horsepower and 568 pound-feet of torque. That means a 0-60 time of less than 3 seconds, and a top speed of 211 mph.Is it as attractive as the 488 that preceded it? Arguably not. But, there will be a day when the F8 Tributo becomes a seriously desirable Ferrari, just because of its status as the last 'old-school' mid-engined model. Jaguar F-Pace SVR In any other circumstance, the Jaguar F-Pace SVR might be viewed as yet another failed high-performance SUV. But, this car is much more special than most in its class. One of these was the final combustion-engined Jaguar ever produced! It's powered by Jaguar's tried and trusted 5-liter supercharged V8, and its performance figures are actually among some of the best from a high-performance SUV.But, it's not the performance that's special about this car. It's the fact that it genuinely could be the last combustion-powered Jaguar ever. It really is the swansong of old-school engineering from one of Britain's most legendary marques. Because of that, it wouldn't be surprising if these cars became genuinely sought-after. Mazda RX-8 MazdaThe Mazda RX-8 is often considered as an ugly duckling in the Mazda rotary family. It certainly wasn't the greatest replacement for the legendary RX-7. But, it is the final pure rotary car Mazda ever made. For that alone, it deserves to have some recognition. This surprisingly practical sports car (it has four doors, four seats and a decently-sized trunk) used the 1.3-liter twin-rotor Renesis engine, in 4-port and 6-port variants. The 6-port is more powerful, producing up to 232 horsepower in the facelifted 2008-2012 cars.The RX-8 still has all the same foibles that rotary-engined cars have. But, that also means it has all the same wonderful and unique characteristics of a pure rotary sports car. It revs all the way up to 9,000 rpm in the 6-port versions, and that power is delivered in an almost EV-smooth fashion. Not much else drives like an RX-8, and that alone makes it worth celebrating in today's world. Mercedes-Benz C63 AMG (W204) Mercedes-BenzPretty much every single Mercedes enthusiast on the planet loves the W204 Mercedes-Benz C63 AMG. There's a very good reason for that. This was the final AMG-branded C-Class to use the legendary 6.2-liter naturally-aspirated V8. This is widely considered to be one of the best engines to ever come out of Affalterbach. It's also arguably the last-ever 'old-school' AMG V8. After this point, Affalterbach-built V8s all became smaller and turbocharged.This car, then, is one of the final examples of a true teutonic muscle car. It's incredibly comfortable, yet incredibly lairy. That naturally-aspirated V8 sound and power will never get old, too.Sources: Bentley, BMW, Chevrolet, Ferrari, Jaguar, Mazda, Mercedes
