1996. During the championship, Nannini was still driving for Alfa Romeo and the Nurburgring debut of the new Lancia-based 90° 6V engine (2498 cc, 98X55,2 mm, 490 HP at 12,000 rpm)

EC2277, if you saw Lancia's gamma of the 80-90th, you would clearly see the only one V6 90° engine - PRV 6V with aluminum cylinder block for Lancia Thema. This engine was used for Abarth SE065, SE067.

Busso V6 has 60° between bunks of cylinders. It was used for the Abarth SE052, SE057, SE057E, SE062.

No,the V6 90° engine was based to the V8 Montreal engine whitout two cylinder.

PaoloGTC sicuramente avrà l'articolo in questione in archivio (dev'essere del 1996)

Corretto. Dopo le esperienze disastrose del 95 la macchina venne stravolta di nuovo nel 96.Per abbassare il baricentro si volle aprire la v del motore,ma il regolamento prevedeva che si partisse da un motore di produzione.E si adottò il basamento del v8 della montreal privandolo di una coppia di cilindri.Allo stesso tempo si eliminò gran parte della gestione elettronica,ritornando alle origini e adottando un retrotreno simile alla 75 turbo di gruppo A di qualche anno prima.

Questa parte devo finirla di scrivere nella discussione che feci e che ho riportato.

Se penso che oggi, per quelle sportellate e toccatine, gli steward andrebbero a rompere il caxxo fino allo sfinimento...::~

Oggi, delle sportellate del genere sarebbero state sanzionate con un mese di Stop & Go :D

Guys, I have one question, what's more reliable source QR or Centro Documentazione Alfa Romeo? :)

This is full article about DTM-ITC from closed Alfawiki, alfisti.com, the one of the most reliable source about AR ever :)

DTM - ITC

After a thrilling 1992 racing season when the 155 GTA cars dominated the Italian SuperTurismo championship, Alfa Corse decided to step up its game in 1993 by developing various track versions of the 155. Its most ambitious goal was the DTM (Deutsche Tourenwagen Meisterschaft), the German touring championship, an extremely competitive event with a huge public following (an average of 62,800 spectators in 1993).

THE CAR

Taking advantage of the adaptation possibilities granted by the generous D1 category regulation, the standard production 155 was drastically revised. The compact 60° V6 dry sump light alloy engine with a capacity of 2498 cc (93 x 61.3) and cylinder head with four valves per cylinder (intake in titanium), was able to develop 420 HP at 11,800 rpm and a maximum torque of 30 kgm at 9,000 rpm with a weight of just 110 kg. On the 155, it was arranged longitudinally overhanging the front axle, supported by a sub-frame.

The six-speed gearbox was connected to the power unit by a magnesium casting, which also incorporated the oil reservoir (8 litre) and the front differential. The transmission was four-wheel-drive with epicyclic transfer box, viscous coupling and self-locking sliding front and rear differentials. Drive torque distribution was 33% to the front and 67% to the rear.

The vehicle body measured 4,576 mm in length, 1,750 mm in width and 1,410 mm in height with a weight of 1,040 Kg and weight balancing of 50% over both axles. The body was made out of carbon fibre and the frame was strengthened by a cage-type roll-bar. As on the 155 GTA, the suspension configuration was a McPherson on all four wheels, with elliptical cross-section tubular lower wishbones and trailing arms on the rear end for adjusting toe-in with stabiliser bars adjustable by the driver.

From the second race, the 19’’ wheels were abandoned in favour of 18’’ wheels that were better suited to the numerous town routes. The injection system was also improved during the racing season, being fitted with two injectors per can, and a new sequential gearbox was adopted.

THE VICTORIOUS DEBUT. 1993

The Alfa Corse team, managed by Giorgio Pianta, therefore fielded two 155 V6 TI cars, driven by Nicola Larini and Alessandro Nannini. Another pair of twin cars were also driven, for the Schubel team, by Giorgio Francia and Christian Danner.

The car's victorious debut at the Zolder track was simply the first step towards Nicola Larini winning the title, beating the current champion Klaus Ludwig, driving for the imposing Mercedes mega-team. Larini notched the highest number of victories in the DTM's history, no fewer than 10 in 20 races, joined by another two wins obtained by Nannini and a non-league race win in Donnington.

1994 SEASON

Enthusiasm for the win in 1993 and excellent sales feedback in Germany for the 155 cars prompted Alfa Corse to continue developing the car for the following season. The car was improved in every part: the power unit was lightened, lowered and equipped with air-controlled valve return, which bought benefits, particularly in terms of power delivery. The car body was lowered by no less than 60 mm and its aerodynamics were significantly altered.

The biggest changes were, however, linked to an increase in the use of electronics: a special ABS, developed by the American Kelsey-Hayes (an optical speed scanner prevented the simultaneous blocking of all four wheels in a four wheel-drive configuration: racing conditions can mislead a normal ABS not built for the stresses of the track, where decelerations of more than 2 g are possible) and an electronically-controlled active suspension system developed in conjunction with TAG Electronics. On the safety front, the normal equipment was joined by a new airbag on the drivers steering wheel.

Five new 155 cars were lined up at the beginning of the championship: two official Alfa Corse cars driven by Larini and Nannini. Another three managed by Schubel Engineering for France, Danner and the Danish new-entry Chris Nissen. The six 1993 cars were leased to private individuals. Nannini dominated the first part of the championship, winning seven out of the first 10 races, but the veteran Ludwig, with his improved Mercedes, got his own back and was awarded the driver's title, even though Larini was not short of successes. At the end of the season, he was also joined by Stefano Modena, making Alfa the make that scored most victories.

The 1995 SEASON (DTM and ITC)

The popularity of D1 class cars (Class 1 for the FIA) had risen considerably and the number of non-league events outside the normal DTM circuit was growing. In 1995, there were no fewer than five, grouped by the FIA into the new ITC (International Touring Car series) championship. At the same time, the regulations had also become less strict, meaning that the already-extreme touring cars now retainined only the silhouette of the original model: the chassis' and suspensions were redesigned.

At the championship, Alfa Romeo lined up six official cars and three for private individuals. Larini and Nannini with the Alfa Corse-Martini Racing team, Stefano Modena and Michael Bartels for Euroteam, Michele Alboreto and Christian Danner with Schubel. The first part of the championship was beset by delays in developing the new car (the “Step 2”) but at last it was ready. The season brought slim pickings and concluded in Magny-Cours with the ITC title going to the Mercedes driven by Bernd Schneider, already the DTM champion.

1996 SEASON (ITC)

1996 saw the DTM disappear to be replaced by the ITC, which had now become a world championship with 13 double events under its belt: opening in Hockenheim and closing in Suzuka. Alfa Corse fielded no fewer than eight official 155 cars: Larini e Nannini (Alfa Corse-Martini Racing), Giancarlo Fisichella and Christian Danner (Alfa Corse-TvSpiefilm), Stefano Modena, Michael Bartels, Gabriele Tarquini and Jason Watt (Alfa Corse-Jas).

The 1996 car was a further development of the ill-fated Step 2: the track was widened by 30 mm because the standard production car had also been widened. The tank arrangement and aerodynamic configuration were also altered. The transmission was improved with the adoption of a sophisticated X-Trac transmission, while the power unit was further improved to the threshold of 460 HP. The electronics was upgraded to a new Magneti Marelli system.

During the championship, Nannini was still driving for Alfa Romeo and the Nurburgring debut of the new Lancia-based 90° 6V engine (2498 cc, 98X55,2 mm, 490 HP at 12,000 rpm) put him back in the running for the title. At least until the penultimate event in San Paolo, where wins by Nannini and Larini were not enough to snatch the title from the Opel Calibra driven by Manuel Reuter.

Already in Magny-Cours Alfa Romeo had stated its intention of abandoning the championship. This decision was soon followed by Opel, thus writing the last chapter in the short yet exciting era of the ITC. Escalating costs (following liberalisation of the electronics and suspension, Mercedes soared to a new level of technology in 1996 with the wholesale adoption of composite materials for the chassis) and failure to achieve proportional feedback in the media and market put a premature end to the championship.The 1996 cars therefore represented the maximum flowering of technology applied to racing cars, which were allowed to develop virtually untrammeled in an era when even Formula 1 had adopted extremely strict regulations, particularly on electronics.

Ma infatti...ma dove s'è visto mai derivare un motore da corsa da un PRV! Come se in Alfa Romeo non fossero capaci di sbrigarsela diversamente...ma dai per favore...

Alfawiki o alfisti.net puo' dire quello che vuole. Ma io mi rifiuto di credere che un costruttore come Alfa Romeo avesse bisogno di fare una porcata del genere.

E comunque 4R i dati non li scriveva di testa propria, ma dalle cartelle stampa ufficiali.
