Alfa Romeo 155 - BTCC 1994
Alfa Romeo 155 Silverstone
The Alfa Romeo 155 first joined the BTCC in 1994 following relatively successful seasons in both the Italian and French championships. Alfa was keen to take the BTCC title in its first season, but a poor result at the end of season World Cup made the team realise that the 155 would need a helping hand if it was to beat the highly competitive BTCC field.
Over the winter break, Alfa Romeo designed and built a new 'Silverstone' version of the 155 which sported a new rear wing and adjustable front spoiler. Both these aerodynamic devices added little to the cars performance on the road, but on the track it would give them the traction and braking advantage they were looking for.
The cars themselves are built by Alfa Corse (Italian for Alfa Racing) in Turin, using standard pressed steel production body shells taken from their production line at Pomigliano, near Naples. Initial chassis preparation is handled by local Turin company Albatech, who also assisted with the technical design of the cars, and so good is their work that the 155 comes in a full 40kgs below the minimum weight limit.
To achieve this, Albatech remove all unessisary mountings and brackets before seam welding the stress areas and adding a tubular steel roll-cage, which extends to support the front and rear suspension pick-up points. All this work not only produces a light car, but also one that is twice as stiff as the road going version.
With the chassis complete, the engine and drive train are then added. Unlike the road cars, the race engine is not based on the 2 litre twinspark varient, but rather a rally proven in-line 4 which has also been used in Abarth's Fiat Tipo F3 cars. The basic iron block is from the 164 model, while the head is the taken from the 155 Q4 turbo but rotated through 180 degrees.
Rotating the head allows the colder (and denser) air front the front of the car to be fed straight into the engine. A large and expensive carbon fibre air box contols the air flow into the throttles, keeping it away from the power-sapping high under-bonnet temperatures. Each of the four throttles feature a soleniod operated injector up-stream of the butterfly valve.
The reverse head also allows the designers lower and tilt the engine rearwards by 27 degrees to bring much of its weight inside the wheelbase. This has resulted in a favourable 67%-33% front-rear weight distribution for the cars.
Inside the engine, each cylinder has a "square" bore and stroke of 38mm. into which are fitted Mahle aluminium pistons, each with 2 chrome plated cast-iron piston rings. A single Champion spark plug is centrally located in the roof of each combustion chamber and ignition is controlled by a Formula 1 standard Magnetti Marelli management system, which features a separate coil for each plug.
Engine lubrication is managed by an Abarth designed dry sump system, with oil being fed by a Bosh pump from a 12 litre tank housed in the boot. A single oil cooler is positioned next to the main custom built water raditator which is housed behind the front grille.
Power output for the car is estimated at a conservative 280-290 bhp, but as with all SuperTouring teams an exact figure is never quoted. Engine re-builds are scheduled for every 700kms, and each rebuild takes 80 man hours.
Power from the engine is passed through an AP Racing sintered clutch into a custom built Hewland HP2000 Sequential gearbox. A hyraulic ZF plate type differential is used to help traction which has the benefit of allowing driver adjustment during the race.
Wheels are MIM cast magnesium alloys, measuring 18inch X 8.2inch wrapped in Michelin rubber, and they hide Brembo groved and ventilated cast iron brake disks.
The Brembo brake callipers, 8 piston front and 4 piston rear, are based on those used in the Alfa Class 1 touring cars and feature four Performance Friction carbon metallic pads per wheel at the front and two Pagid pads at the rear.
The 155 suspension features MacPherson front struts and a trailing rear arm set-up, which must also be used in the race cars. Eibach springs and Bilstein non-adjustable mono-tube dampers are fitted, both of which have been specifically developed in conjunction with Alfa Corse. Abarth fabricate steel trailing arms to replace the standard cast-iron versions and both front and rear anti-roll bars are driver adjustable.
Inside the cabin is a Sparco racing seat and TRW Sablet harness. The 155 has a power steering system identical to that used by the Lancia Delta Group B rally car. The standard instrumentation is replaced by a Magneti Marelli LCD dash, which is also the front end for the data aquisition system. A fire-extingusher and fuel tank are also housed behind the driver, the latter being a 70 litre ATL fuel cell situated under floor where rear seats would normally be placed.

Alfa Romeo 155 D2
Alfę 155 D2 napędzał 4-cyl., rzędowy silnik, montowany poprzecznie i nachylony do tyłu, z dwoma wałkami rozrządu w głowicy, napędzanymi paskiem zębatym i z 4 zaworami na cylinder, o pojemności skok. 1998 cm3 (równe wymiary średnicy cylindra i skoku tłoka: 86x86 mm). Blok odlany został z żeliwa, głowica ze stopów lekkich. Zasilanie realizowano przez elektroniczny wtrysk wielopunktowy Weber-Marelli, stopień sprężania 12,5:1, w układzie zapłonowym 2 świece na każdy cylinder. Moc 275KM/8200 obr./min., moment obr. 240 Nm/6000 obr./min.
W 1994 r. nastąpił wzrost mocy do 285KM/8500 obr./min. W 1995 r. wprowadzono kolejne drobne zmiany w osiągach: moc 285KM/8300 obr./min., moment obr. 248 Nm/6500 obr./min. W 1997 r. dokonano jeszcze jednego wzmocnienia: moc 305KM/8500 obr./min., moment obr. 270 Nm/7000 obr./min. Normy techniczne klasy w zakresie silników zakazywały stosowania doładowania oraz ograniczyły pojemność do 2 litrów, a prędkość obrotową do 8500 obr./min.
Najważniejsze sukcesy 155 TS D2 to mistrzostwo Hiszpanii, które zdobył Adrian Campos oraz drugie miejsce Antonio Tamburiniego w Italian Super Turismo. Ostatnim zwycięstwem 155 TS był kolejny tytuł w hiszpańskiej serii Superturismo, zdobyty przez Fabrizio Giovanardiego.
W Polsce Alfą 155 TS D2 startowali w wyścigach płaskich i górskich Andrzej Dziurka i Tomasz Wywiał.
