Alfa Romeo GTV and Spider Technical Specification
GTV and Spider utilises highly modified ‘Fiat Type Two’ (Tipo Due) platform. Other cars made on this platform: Alfa Romeo 145, Alfa Romeo 146, Lancia Delta, Fiat Tipo, Fiat Coupé. Type Two differed from Type Three in that it lacked the possibility to mount an all-wheel drive system.
The fuel tank has a capacity of 70 litres (18 US gal; 15 imp gal). The battery, CD autochanger are located in the boot, and the fuel tank is ahead of the rear axle line, behind the rear seats for increased safety. The power assisted steering has a very high ratio, giving 2.2 turns lock-to-lock. The bonnet and bootlid are supported on nitrogen filled struts. A spacesaver spare wheel was supplied, and there was a no-cost option of an aerosol can of tyre repair sealant. This was a factory standard from 1998 as it increased the usable size of the very small boot to 155 litres (5.5 cu ft).
As would be expected, the GTV has a much more rigid chassis, up to 64% stiffer compared to Spider, although considerable work was done on the Spider to reduce the traditional convertible problem of scuttle shake.
Weight distribution for four cylinder engined car is 61% front/39% rear and for a V6 is 63% front/37% rear.
Chassis torsional rigidity (for 1996 car) GTV: 110,000 kg/rad, Spider: 40,000 kg/rad.
Wheels are 15 inch perforated steel as standard, 16 inch teardrop alloy wheels with 205/50 tyres were part of the Lusso option package. From Phase 2 and 3 16 inch teardrop alloy wheels became standard with factory option of 17 inch alloy wheels and 225/45 tyres.
2.0 V6 TB models have windscreen fluid reservoir in the boot, whereas the rest have them under the bonnet.
Criticisms of the model have been that it is hard to park due to its large turning circle and low seating position, which mean that the end of the bonnet and corners are outside the driver’s line of sight. The doors are very long and need plenty of space in a car park.
From 2000, a resin glass hard top was available for the Spider. The top is fitted with a glass heater rear windscreen which can be connected to a special socket on the left side panel of the vehicle. The top is fitted on the vehicle with the top folded in its housing and the hood cover closed. When the hard top is fitted, the operation of the electric hood opening and closing switch is inhibited.
Spider has reinforcements in the windscreen pillars to make them undeformable if the car overturns and the partition behind the seats stiffens the part of the body.
From the begining cars had 2 anti-intrusion bars inside the doors, while from 1998 there is only one anti-intrusion bar.
