Lancia Delta Integrale Evoluzione: Lengthy Dwell The Group A King

If I requested you who essentially the most profitable producer within the World Rally Championship was, what would your guess be?

Toyota? Unsuitable. Audi? Not even shut. By the point Lancia had withdrawn from the World Rally Championship, the Italian automaker had amassed 11 producer titles and 4 drivers titles from 46 WRC occasion wins.

Whereas the 037 and Delta S4 which predate the Delta Integrale have been extra outrageous, this inventive freedom happened because of the relaxed ruleset on the time. Group A got here into impact to try to quell the ever-increasing speeds and half-hearted approaches to security, whereas attempting to maintain the vehicles extra akin to their road-going counterparts. Group B dictated that 200 road-going vehicles wanted to be created, whereas for Group A it was 5,000 in 1993, that means producers needed to forgo unique supplies and time-consuming building strategies.

The pair of Delta Integrales on show at Rally Replay want Goodwood within the UK signify the final word incarnations of Lancia’s WRC effort. Known as the Deltonas – which interprets as ‘large Delta’ – these two vehicles have been constructed for consecutive years. However whereas they could seem largely the identical, there are a myriad of variations between the 2, highlighting the fixed growth and relentless pursuit of efficiency that the Abarth workshop the place they have been constructed employed.

However these weren’t the one large adjustments. Jolly Membership (assume Prodrive in Subaru phrases) took over Lancia’s WRC effort and growth program from the beginning of 1992, albeit nonetheless understanding of the Abarth workshop with all the present workers. Lancia nonetheless wrote the cheques.

In 1993, some workers have been moved over to the Alfa Romeo Touring Automotive programme, however Lancia nonetheless funded the WRC effort, as evidenced by the vehicles carrying ‘TO’ prefixed licence plate for Turin – the place they have been based mostly – versus ‘MI’ plates for Milan, Jolly Membership’s base.

1991 Repsol Lancia Delta HF Integrale Group A – TO 35378S

Constructed in direction of the tip of 1991, this automotive was assigned the registration TO 35378S and served as a take a look at mule for the works staff to develop Lancia’s 1992 WRC entry. Among the adjustments included new Brembo callipers permitting using 332mm discs on tarmac (313mm for gravel) and revised magnesium-cased Abarth gearbox and differentials.

The automotive additionally obtained a extra superior ECU and digital dashboard equipped by Magneti Marelli.

The 1991 growth vehicles have been the primary to obtain the broader physique panels, which allowed for up to date Bilstein suspension and high mounts, and a wider monitor. That is what gave them the Deltona nickname.

TO 35378S was pivotal within the 1992 season, with the developments carried out straight supporting the staff in reaching victory on eight rounds and successful that 12 months’s WRC Producers’ Championship.

In December 1992, Carlos Sainz got here onboard, bringing his title sponsor Repsol with him.

Sadly, Sainz’ season was plagued with quite a few points, and though he got here near successful rounds within the Lancia on a number of events, it by no means occurred. After one 12 months, Sainz moved to Subaru, final driving a Delta within the 1993 Race Of Champions (the place he completed second behind Didier Auriol, who had left Lancia on the finish of the ’92 season for Toyota) earlier than testing in an Impreza simply two days later.

1992 Martini Lancia Delta HF Integrale – TO 13721T

TO 13721T debuted in gravel specification for the 1000 Lakes Rally in August 1992, to proceed the success Lancia was having that 12 months.

Regardless of solely having a small finances to work with, the vehicles have been frequently improved. A rule change mandated using 8-inch-wide (relatively than 9-inch) wheels, which tremendously upset the Delta’s dealing with traits.

TO 13721T was completely pushed by Auriol in 1992, who had an extremely eventful season, with victories in Monte Carlo, France, Greece, Argentina, Finland and Australia. The French driver narrowly missed out on the WRC Drivers’ Championship title on the remaining spherical held within the UK by a mere two factors, owing to terminal engine harm.

See that little adjustable pot tucked down out of view? That allowed the co-driver to decrease increase ranges for extra tough situations, finally making the automotive extra drivable.

The Fiat 242 van parked alongside is a devoted recreation of the service automobile used within the 1983 season in the course of the Group B period. By the point Group A got here round, the staff started utilizing greater Iveco vans.

There’s no debating the success that Lancia had within the World Rally Championship, however the firm right this moment is unfortunately a shadow of its former self, promoting only a few fashions with restricted success outdoors of Italy. ‘The brightest stars burn the quickest’ can be an apt description of the success Lancia had within the WRC. With Toyota being the following closest OEM presently competing with seven WRC Producers’ Championship titles to its title, the Lancia document will stay for at the very least a short time longer.

A particular because of Adam Midghall, Supervisor at Rally Replay for sharing his huge Lancia data for this story.
