Alfa Romeo V6 DTM: A 12,000rpm French Engine

[@gabork.8715]

The base of the 90 degr. was the Lancia Thema V6 engine which was based on the RPV cooperation. Except V90 angle and bore distances there were no common parts with the RPV engine, but was a completely new constructions of the Lancia race department. So it was really an Italian race engine.

[@VisioRacer]

Yes, exactly

[@GitonIcon]

Engine block was the same. Alfa made new heads, but block was PRV as homollogation required. So, it was tuned PRV

[@alexjenner1108]

@@GitonIcon The block would have been a specialised cast or billet racing block with no PRV parts. The homologation is just a piece of paper with the cylinder bore spacing written on it, nothing more.

[@KootBear]

this is some good info, ty guys

[@GitonIcon]

​@@alexjenner1108Using your anallogy, this PRV-Alfa was more Alfa than Alfa V8 without two cylinders. There is no shame here being put on Alfa, besides Alfa was manufacturing under licence several Renault models including Dauphine, 8 and 4. If they didn't feel bad about it why should any Alfa fan? You'll never hear fan of Renault or Volvo saying "No Peugeot WM P88 with 900HP reaching 407 kph wasn't PRV, it was just angle.

Sorry Man, but the 1996 Alfa Engine was not French. In the same interview you say, Sergio Limone says that the technical aspects to respect for the new regulamentation were the angle of the V for V6 engine and the the distance from the centers of the cylindres. So, on the documents were released the Montreal V6, but it has too short distances between cylindres, and thanks to a society in the last years of the 80s, Lancia and Alfa were the same Brand, and the PRV equipped the Lancia Thema 6V and the Lancia Thema Limousine, so it was addicted to have the technician values to can be used as shield... the V6 1996 Alfa engine was in experimentation from 1994, and Nannini tested it after the initial develop of Giorgio Francia...

[@VisioRacer]

It was not, but that’s not as important. The base was a Swedo-French developed engine that was turned upside down into a full race engine. The “French” is there just to catch attention.

[@JoeDaeHimself]

Dear friend, this is incorrect, in the video by Cironi that you are using, LIMONE clarify that the engine only shares the V angle with the PVR and nothing else, moreover, FIAT was going to abandon the DTM so they didn't want ANY new engine development, LIMONE and his team basically went rogue and launched this new engine. Again this is not a PRV, this is a brand new engine made by Pino Aprile that shares the V angle with the PRV.

Since 1993 Alfa Romeo used the Italian V6 Busso (V6 60° 470 hp) engine for the 155 DTM . In 1996 Alfa Romeo used the French PRV V6 90° engine modified by Alfa Romeo to reach 490 hp

[@blackflagqwerty]

The car vaguely resembled a 155 road car and that's about all it had to do with it. It was a purpose built racing beast, take note F1 this is what a V6 SHOULD sound like.

[@driver46]

Truly iconic race car , made so many Sundays special for me as a kid .

[@theAngelofhevn]

From Wikipedia about the engine: The PRV was also the basis for the 90° V6 engine used by Alfa Romeo in the 155 V6 Ti in the 1996 DTM/ITC season from Silverstone onwards.The engines in that series required the use of bank separation angle and cylinder bore spacing from a production based engine, and as a 90° V6 has greater room between banks than a 60° V6 for a more optimal induction system, Alfa Romeo used the PRV as a basis as it had been used in the Lancia Thema, a car which shared its platform with the Alfa Romeo 164, as well as the Fiat Croma and Saab 9000. Other sources declare that the 90° V6 engine in 1996 Alfa Romeo 155 V6 Ti is based on a 2.6 L V8 from 1970 Alfa Romeo Montreal with two cylinders removed, as allowed by the rules, however the FIA homologation documentation shows the homologated production engine was a "2850cm³" capacity "V6" engine. The bore spacing of the Montreal engine was too close to be suitable for the 155 V6 Ti in any case. Limone invented the "Montreal V8" story to throw the press off the scent and to satisfy FIAT management who were unhappy that a non-FIAT group developed engine was being used.

That's an interesting film, thanks. I think it's stretching the truth to say it ran a French engine. It didn't. Yes, it was loosely based on the PRV block in terms of measurements and layout but beyond that there were few similarities. It's a bit like saying the early Bugattis were French cars, when of course they weren't at all.

[@stal5861]

Highly interesting video with some new facts that I never thought about. Such as less valve train vibrations on the gearbox side, which other engines has the same design because of this reason? And the PRV6, a highly disliked engine among car enthusiast in Scandinavia, being used as a building ground in DTM!? Crazy stuff

[@legendaryracing904]

That car sings a sweet song 🎵

[@dadoVRC]

Wait wait wait.... Sergio Limone in the Davide Cironi's video tells another story. They were in struggle finding an engine in Alfa Romeo's history with the needed dimensions, the rules needed only that, so V angle and the bore spacing to allow the right bore diameter to reach high rpm. Since they were and are in the FIAT galaxy, they had the option of using the PRV dimensions, since FIAT was part of the PSA joint venture. But that's NOT A FRENCH ENGINE. It has only the V angle and bore spacing of the PRV, just for rules needs, but it was completely engineered by Alfa Corse. Don't spread wrong claims, please.

Misleading title, in your opinion the team of engineers who created the engine of the Lancia Delta S4 (700-800 HP), the first car without turbolag, needed to go and get an engine block from somewhere else, if they hadn't been forced by budget reasons and various regulations. Engineer Limoni and Engineer Lombardi are among the protagonists of the Delta S4 Engine and Lombardi is the designer of the Ferrari F1 V12, the engine with the most beautiful song ever, the one on which Senna complimented Lombardi for the incredible acceleration; the same engine that Schumacher wanted to keep instead of the V10

[@_..-.._..-.._]

It’s not misleading, they “used” a French engine to beat the rules and by used they meant as a scapegoat to get the design parameters they wanted. Too many people misunderstanding that. If not for the PRV bore spacing and bank angle, they wouldn’t have had the same results from the busso architecture. We all know the engines were 100% Italian designed and 100% race spec
