The Most Over-Engineered V10 Ever Put In A Production Car

When you think of legendary performance engines, what are the first few that come to mind? Maybe the Ferrari F140 V-12 or the Toyota 2JZ-GTE inline-six? Don't forget the small-block Chevy V-8 or the Honda K-Series inline-four. We have been blessed with so many wonderful engine platforms over the decades. Yet, the list is very short and ultra-competitive when it comes down to ten-cylinder examples. The V-10 layout has never been the most popular design for performance applications, so the few platforms that do exist are all notable and well-recognized.

Dodge, with the help of the Lamborghini, created the first production V-10 engine as the heart of the all-new Dodge Viper in 1992. The Viper would be the catalyst that would spark the V-10 revolution. Within two decades, the V-10 would blossom into a full-fledged adversary of the more common V-8 and V-12 layouts. Yet, if there was only one V-10 worthy of representing the entire shortlist, it would be the Porsche M80/01 found in the iconic Porsche Carrera GT, the most over-engineered V-10 ever.

Porsche V-10, There Is No Substitute

To understand what makes the M80/01 Porsche V-10 engine so over-engineered, we need to take a look at its history. Porsche is one of the most successful brands in motorsports, and in 1996 and 1997, the German company had just won consecutive Le Mans titles.

This success came thanks to the Porsche WSC-95 LMP car, which was powered by a high-strung race variant of Porsche's bread-and-butter turbocharged flat-six. Porsche returned to the 1998 season and, amazingly, won the LMGT1 class with the all-new 911 GT1-98 chassis powered by a twin-turbo flat-six engine. Yet, this three-peat would mark the end of Porsche's Le Mans dominance as 1999 would not provide the same success due to a new set of rules and regulations.

The Failure Of The Porsche LMP2000

In 1999, Porsche didn't even send a works team to fight for the Le Mans title, instead focusing their efforts on development for the following season. Porsche had planned to introduce a V-10 engine as the new heart of their 2000 Le Mans effort, dubbed the LMP2000, which required additional time and cost. This V-10 unit was based on a scraped V-12 project from their Formula 1 effort with the Footwork F1 Team back in 1991 (which we'll discuss soon).

Yet, by the end of 1999, the LMP2000 was also scrapped, and the promising chassis never once saw the starting grid of an official race. Porsche's official reasoning for the discontinuation of the LMP project was "we are broke". Alternative justifications have been reasoned since, including the theory that the canceling of Porsche's LMP effort was because of German corporate politics. It is said that Audi/Volkswagen stated, "We'll help you build the Cayenne SUV, but no more racing, okay?" Porsche, on the brink of financial collapse, had no option but to agree. Audi would go on to conveniently dominate LMP racing for the next decade-plus, while Porsche watched from afar and cried in the corner.

Broken Dreams Turn Into New Realities

Despite their racing efforts being shunned by their German overlords, Porsche was not about to let all their developmental contributions go to waste. If they couldn't race this V-10 engine and chassis, then they would do the next best thing: make it into a street-legal race car. By 2000, the V-10 engine had been spotted in the first reveal of the Carrera GT concept car at the 2000 Paris Motor Show, and it drew significant interest.

Thanks to Audi's bailout and the immediate success of the Cayenne SUV, Porsche decided to take the leap of faith to make the V-10-powered Carrera GT a reality. On January 31, 2004, the Porsche Carrera GT went for sale in the U.S., bringing the entire development of the V-10 engine full circle. Porsche's partnership with Volkswagen/Audi may have killed their motorsport endeavors at the time, but it did save their brand from disappearing off the face of the Earth. Sometimes, things end up working in mysterious ways, and the Carrera GT's development is one of the most fitting examples of this.

Porsche's Complicated Relationship With Formula 1

If you recall, we mentioned that Porsche's M80/01 V-10 found in the Carrera GT was first a V-12 engine intended for use in an early 90s Formula 1 car. Porsche had participated in Formula 1 a decade prior, but left the sport after four years of an unsuccessful partnership with McLaren, where they provided the turbocharged V-6 platform that powered the McLaren-TAG MP4/3 chassis. By 1990, regulations introduced the 3.5-liter naturally aspirated platform as the new homologation standard. Thus, Porsche decided that their V-12 effort, dubbed the Porsche 3512, was something of a second chance at glory.

The Plight of Porsche's Uncompetitiveness

The reality was that Porsche was never the best at building V-12 engines, and their experience was limited, at best. The 3512 V-12 was, by all means, a failure and uncompetitive. In a sport where every milligram matters, the Porsche 3512 weighed over 100 pounds more than the V-12 platforms of rivals Ferrari and Honda. The engine was also larger than anticipated, so the chassis also had to be redesigned to accommodate the unexpected size difference, making the new chassis ineligible and missing the entire debut season. During the 1991 Mexican Grand Prix, four of the seven Porsche 3512 engines failed, and Porsche suffered their greatest public humiliation ever.

From Humiliation To Excellence

Since the '60s and the introduction of the 911 chassis, Porsche had managed unrivaled motorsport success across multiple disciplines. This '90s Formula 1 debacle would be their first real motorsport blunder, and it would have a serious impact on the brand, as they have not returned to the top flight of motorsport since. Yet, once the opportunity to utilize the development costs of the 3512 V-12 became considered with the introduction of the new sporting regulations for the 1999 Le Mans season, Porsche went back to working on the V-12 engine and redesigned it as a larger displacement V-10. Although this platform was also doomed to never see motorsport success (it wouldn't even see a race), it did lay the foundation for future greatness, as we'd find in the Porsche Carrera GT.

The Raw Details Of Porsche's V-10 Masterpiece

Porsche described the Carrera GT in their promotional brochure as "Over 23,000 racing victories. Expressed in a single car." Although that is a bit ironic considering the development of the car was riddled with failures, it was true. The Carrera GT is the culmination of countless successes and failures, and the resulting product of those tribulations is nothing short of a masterpiece. Let's break down some of the M80/01 V-10's key details to demonstrate how you turn true stubbornness into universal acclaim.

"Less Weight. More Porsche"

Porsche

When Porsche's M80/01 V-10 was first noticed at the 2000 Paris Auto Show, it was featured as a load-bearing structure within the Carrera GT chassis with no subframe. Once it was determined this would be a bit too race car, the engine was instead placed in a three-point carbon subframe. The goal was always to have this mid-engined V-10 lie as deep into the chassis as possible to ensure a low center of gravity, the flat-six engine's most deemed quality.

This is also why the twin banks of the cylinders are arranged in a low-slung 68-degree V orientation, adding to the central theme of a low center of gravity. With a dry weight of 452 pounds, Porsche finally managed to beat the Ferrari V-12 found in the Enzo, which came in at 496 pounds. Part of this weight saving can be attributed to the Nikasil-coated bores, which allowed less friction and weight compared to traditional cast-iron cylinder sleeves. This also means the engine can't be rebuilt in a traditional sense, but rather, must be resprayed if refreshed. Not that too many people will ever have to worry about the long-term maintenance of a Carrera GT, but we digress.

Porsche did everything possible to reduce weight in the engine and the chassis, including the use of magnesium wheels, as pictured above. So was Porsche's only V-10 perfect? No, not exactly, but it didn't need to be. No trophies or championship titles were part of the plan once the Carrera GT became a road car. Yet, we believe that the special circumstances that gave rise to this V-10 add to its unique character. Its original dream was motorsport glory, but destiny had other plans. Being an integral part of one of the most visceral expressions of automotive excellence is too bad either, if you ask us. If there is anything to learn from this story, it's that if you have a dream, sometimes you just have to go for it.
