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.

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.
This is what the F1 V6 engines should sound like, they could rev up to 15k rpm, be sized up to 2 liters and remove the hybrid system, or make it smaller and lighter. Boom, more power, more sound, more fans, more revenue but they're caring about "environment"
Seems like someone studied Cironi's videos 😅 good job This is one of my top 3 cars ever built, it's simply F1 tech in a street looking derivative racecar, it was 20/30 years ahead of others racing series. It marked a peak in technology development before the electrification and computer era (despite the super advanced systems for that time). ❤
Il motore della seconda versione della 155 DTM aveva solo le misure caratteristiche riprese dal PVR per motivi di regolamento ma era un progetto nuovo dei tecnici dell'Alfa Romeo
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
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.
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.
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
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.
Never Alfa used the PRV. The competition fa engine has only the same intercentre piston measure. This engine was totally new and designed by ING. Limone.
Absolutely gorgeous machine, if i had the cash id do a full rep except losing all the interior. Please run a full video on the btcc version which absolutely dominated with tarquienie at the wheel . Cheers 👍✌🏻
Yes please. I was at Brands Hatch for the BTCC and one of these cars was parked on a trailer in a public area behind the main grandstand, IE not in the paddock or pits. I took the opportunity to get on the ground under the trailer and have a good look. Those were the days.
@@philiptownsend4026 that would have been an amazing opportunity, im jealous. We had a new black 155 1.8 ts at the time tarquienie was dominating. Loved that car, even the motors rocker cover looked great. Aluminium with alfa romeo in red. Hopefully we get a video on the btcc model you actually got to see up close.definitely that was my favourite btcc era 👌🏻
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.
Eh so ragazzi,magari inglesi o francesi e magari pure un po' invidiosi. I tedeschi non possono insegnarci nulla in fatto di motori, figuriamoci gli inglesi e ancor di più i francesi....😂
@@massimilianocampana3951Tutti hanno da insegnare e da imparare, ogni produttore ha avuto meriti e primati. La questione è che è stato riportato il falso (clickbait).
@@taketaa5299 doubt it's a mistake. Looking at images of the Busso block, 133mm between the cylinder bore centres seems reasonable. Bigger than I'd have expected though. 133mm is a huge bore spacing for any car engine
It went to re-check that and there is rarely mentioned the Busso’s bore spacing, only two sources I was able to find say the 133 mm figure. Indeed ridiculously wide, but seems legit looking at the engine deck
With this car alfa mashed up the DTM. I loved this time, when formula 1 was interesting. didn't watch F1 since 20 years, too boring. Rally and hillclimb are much more entertainment. And Goodwood. Quattro and Walter.... wish that times back.
It's kinda ironic that one of the most loathed production car V6 engine is also one of the most successful in racing competition... and also the engine of one of the most iconic movie car (DeLorean DMC-12).
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
I,m sorry, but I cannot agree with the text french engine: its the 90° V6 concept that comes from peugeot/volvo co-enginering. Alfa used this CONCEPT to solve the cooling problem that the 60° engine had. The engine was further on totaly alfa romeo
amazing info...I had no idea...always thought the 155 DTM was strictly Busso...go figure in what weird places you find PRV 90 degree V sixes...Delorean...Alpine A310...amazing...I once read somewhere that the V6 in the 155 DTM (don't know which one Busso or PRV) was built to such high tolerances that the head, block and sump went together without gaskets...but I can't find anything about that now anymore
Interesting so the 90 degree V6 only came in 96. I thought the Twinspark was only in the 96 engine but it seems that from this video even the 95 60 degree V6 engine also had the Twinspark heads.
I believe del V 60 degrees was the who destroyed the Germans in their own championship then it was used the V 90 degrees from Alfa Lancia based on PRV engine and then it arrives issue to finish races and don’t forget own they ruined Nannini championship with the worst unfair game to make him spin while was in a position to win.
The only PRV parts used would be the homologation form with 90 degrees and 108 mm printed on that, so I'm pretty sure that piece of paper would fit in the glove box.
As much as I love the M3, the Alfa was such a good looking and sounding car!! And it made the arrogance of the Germans turn into humble boys. BTW in the early days the other drivers lightly pushed the exhaust pipes to slow them down, after that straight pipes were used.
Learn to adapt. Mr Visio is a Slovak and speaks excellent English. Yes he has an accent but don't we all? Tolerance needed. Enjoy the rich English language spoken differently around the world and even differently within single countries. Are you American by any chance?
@@philiptownsend4026 I agree with you wholeheartedly - I am Dutch and fond of accents actually. But to me that doesnt make the narration less hard to follow.
I am sorry but you are totally wrong. The first version of the engine, the one that won the DTM in 1993, was a V6 60° that had nothing to do with France PRV 90 degrees V6. And the second version used the design conception of the PRV engine, it means the angle of the V and the "interasso" of the cilinders. The manufacture was totally italian. So first inform yourself before putting such sensationalistic title to your video.
All correct sir. We must give credit to Guilio Alfieri of Maserati for the first to build a 4v 90 degree v6 for racing though. Alfieri’s creation was raced by Ligier at Lemans in 74 placing 8th overall. Made some 400hp at 11k rpm from 3L. Engine was based on the Citroen SM/ Merak block but with 4v heads
I suggest a correction for the title: Alfa Romeo V6 DTM: A 11,800rpm Italian Engine I also suggest uploading a corrected video, with proper information. And i suggest doing proper research before saying shit. The V6 Alfa is a derivate from the V6 Thema from Lancia and have nothing in common with it, just some paper for proper omologation, is like saying that Nutella taste like shit.
I can't understand why some people persist to believe that the 155 was fitted with a PRV. Watch the video : everything shows a racing engine built from scratch by Abarth. Every part is specially designed for this 12000 rpm race engine. Zero part from a PRV, not a single washer. Abarth built many versions of the engines following the DTM rules. Nothing else. Does the intercylinder distance make the intellectual property ? Absolutely not. But I think that very few people really know what is a car engine, and even less what is a racing car engine.
This engine has only the 90 degrees angle in common with PRV. The other parts were engineered by ex Lancia Martini team. This is NOT a french engine. After that you have to remember that Alfa won DTM with the original Alfa V6 engine with 60 dr angle…
What bloody frnch engine? Limone, Italian. ABARTH Italian, Alfa Italian as much as brand can be. Engine block was at some point used in French-Italian cooperation. Connection ends there. Period. Viva Italia!
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.
Yes, exactly
Engine block was the same. Alfa made new heads, but block was PRV as homollogation required. So, it was tuned PRV
@@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.

@@_..-.._..-.._ I thought it was quite clever myself.
At least one person got it 🤜
Absolutely nooooo. Listen to the whole video again so you understand what was said.
@@philiptownsend4026 PRV engine was used, so I'm correct.
I wish my naturally aspirated v6 would develop 200hp per liter!!! So impressive!
But it wouldn't be drive able! Race engines can only run flat out, that's all they need to do.
12,000 rpm and French makes me very nervous
It isn't French in any way. It was designed and built by Italians in Italy. So no need to worry.
🔥🔥🔥
Lol…a French engine designed by an Italian (& probly in Italy).
Nicola Larini 4ever❤❤❤
Mercedes was the most unsportive team in those days... their cars rearended Alfa Romeo cars, and damagede their exhaustpipes....
I might say this is formula 1 engine by today rules
Wow, I remember this F from granturismo 2
Prv base. But hardly elaborated by Ing Sergio Limone from Abarth.
FORZA RAGAZZZZI
🍀🤍💋
They used a prv in a successful race car!? Wow...20 years after they came out!?
No. The only similarity was the V angle and bore spacing. Everything else built by Italians around those two parameters.
I believe del V 60 degrees was the who destroyed the Germans in their own championship then it was used the V 90 degrees from Alfa Lancia based on PRV engine and then it arrives issue to finish races and don’t forget own they ruined Nannini championship with the worst unfair game to make him spin while was in a position to win.
Do a video covering the most tuneable snowmobile engines
I think you should narrow that down. Maybe the evolution of hillclimb sleds or the 4 stroke takeover and turbos.
This begs the question, would those Alfa Romeo PRV6 parts fit the PRV6 in a Volvo 260?
Because that would be hilarious.
The race engine, used in last models, has only some dimensions in common with RPV engine (used in a Lancia model).
The only PRV parts used would be the homologation form with 90 degrees and 108 mm printed on that, so I'm pretty sure that piece of paper would fit in the glove box.
As much as I love the M3, the Alfa was such a good looking and sounding car!! And it made the arrogance of the Germans turn into humble boys. BTW in the early days the other drivers lightly pushed the exhaust pipes to slow them down, after that straight pipes were used.
Interesting video. My only critique would be that the narration is a bit hard to follow at times due to the overall pronunciation.
Learn to adapt. Mr Visio is a Slovak and speaks excellent English. Yes he has an accent but don't we all? Tolerance needed. Enjoy the rich English language spoken differently around the world and even differently within single countries.
Are you American by any chance?
@@philiptownsend4026 I agree with you wholeheartedly - I am Dutch and fond of accents actually. But to me that doesnt make the narration less hard to follow.
I am sorry but you are totally wrong. The first version of the engine, the one that won the DTM in 1993, was a V6 60° that had nothing to do with France PRV 90 degrees V6. And the second version used the design conception of the PRV engine, it means the angle of the V and the "interasso" of the cilinders. The manufacture was totally italian. So first inform yourself before putting such sensationalistic title to your video.
All correct sir. We must give credit to Guilio Alfieri of Maserati for the first to build a 4v 90 degree v6 for racing though. Alfieri’s creation was raced by Ligier at Lemans in 74 placing 8th overall. Made some 400hp at 11k rpm from 3L. Engine was based on the Citroen SM/ Merak block but with 4v heads
Lies. Alfa Romeo did use their own engine. Just not based on the one found on the production cars
I suggest a correction for the title: Alfa Romeo V6 DTM: A 11,800rpm Italian Engine
I also suggest uploading a corrected video, with proper information. And i suggest doing proper research before saying shit.
The V6 Alfa is a derivate from the V6 Thema from Lancia and have nothing in common with it, just some paper for proper omologation, is like saying that Nutella taste like shit.
French engine? What engine is it
I can't understand why some people persist to believe that the 155 was fitted with a PRV.
Watch the video : everything shows a racing engine built from scratch by Abarth. Every part is specially designed for this 12000 rpm race engine. Zero part from a PRV, not a single washer.
Abarth built many versions of the engines following the DTM rules. Nothing else.
Does the intercylinder distance make the intellectual property ? Absolutely not.
But I think that very few people really know what is a car engine, and even less what is a racing car engine.
French engine? No joke man, please!
why cant we have something like this nowadays?
Simple... Politics!
Insomma, ragazzi, un po' alla volta scooriremo che la 155 DTM era un'auto francese con adesivi Alfa 😂
La meccanica invece era Lancia, quella si
delorean engine
This engine has only the 90 degrees angle in common with PRV. The other parts were engineered by ex Lancia Martini team. This is NOT a french engine. After that you have to remember that Alfa won DTM with the original Alfa V6 engine with 60 dr angle…
Absolute great car but in the end Opel become the most advanced car of the series.
What bloody frnch engine? Limone, Italian. ABARTH Italian, Alfa Italian as much as brand can be. Engine block was at some point used in French-Italian cooperation. Connection ends there. Period. Viva Italia!
