Technical information about the FIAT Tipo 16V

The following are technical specifications taken from the Tipo 16V manual. All figures and facts refer to the 16V model only.


ENGINE

History:

The Tipo 2.0ie 16v derives its power from the legendary Fiat twin-cam engine, an engine whose ancestry can be traced back to 1966 and was designed by the automotive engineering genius Aurelio Lampredi. The first eight valve twin-cam produced 90bhp from 1,438cc's (some 20bhp more than comparable pushrod engines of the day) and evolved into a 1995cc sixteen valve 300bhp turbo powerhouse in competition form, winning no less than 10 world championships in one form or another.

Lampredi incorporated many hitherto unseen innovations into his design including the direct acting camshaft for operating the valves, using shimmed "buckets" between cam and valve assembly as a means of adjustment rather than the now de-rigeur (power absorbing) hydraulic adjusters. Also a lightweight aluminium cylinderhead when most were cast iron and con-rods that can only be described as destruction proof !!!

In "Sedicivalvole" form a 1995cc powerplant produces 148bhp @ 6,250rpm and 18Kgm of torque @ 5,000rpm, 16Kgm of this torque being available from 2,500rpm up to 6,000rpm which when matched to the appropriate gear ratios produce a car with extreme flexibility and thus drivability. The engine is very similar in specification and power output to the 2 litre unit fitted to the Lancia Thema series 2 in 1988, also utilizing counter rotating balancer shafts to counteract the inherent imbalance of the in-line four cylinder engine and thus produce a much smoother if very slightly less responsive power unit.

These are some very high resolution (and therefore very large) cut away diagrams of various parts of the engine together with a cut away diagram of the car.

Specifications:

The basic design of the engine remained the same between the 5 and 3 door models. However the power and torque characteristics changed slightly. In the 3 door model the engine was detuned slightly which reduced ultimate bhp but provided more torque at lower revs.

Balancing:

The engine is equipped with "counterrotating balancer-shafts". They rotate at twice the speed of the crankshaft and serve to balance the dynamic forces that are generated by the crankshaft. As a result these engines operate very smoothly at all speeds.

Dashboard My tipo doing 134mph (216km/h). Before you ask, it was along a flat German Autobahn with no trailing wind a passenger and a full complement of luggage. Click on the image to see a blow up of speedometer. Cruising at 120 mph the oil temperature remained steady at the normal 100oc but pushing the car up to 134mph (216km/h) caused it to creep up to 120oc (maybe I should fit a oil cooler for future journeys!), though hardly surprising as I was doing about 6500 rpm!!. Traffic congestion gets quite bad at times so there are only certain times during the day that these speeds can be obtained.

I found driving in Germany is not as much as it's made out to be. The German drivers consistently tailgate, hardly indicate and don't use any form of acknowledgement to let you pull out. Helped by supped up brakes they also brake as late as possible which is very unnerving if they are approaching from the rear. Many of the cars are extremely powerful big black imposing BMW's or Mercedes Benz.

Some sections of the autobahns are only two lanes, and given the high speeds that the traffic can travel, it makes it very difficult pull out into the inside lane to overtake. You can be for example stuck behind a lorry doing 60 mph, the road can look clear behind so you pull out, only to have, seconds later, a car doing 150 mph coming up behind you. This tends to make journeys an annoying cycle of fast and slow. By the time you have built up a good speed somebody pulls out infront of you slowing you down again.

On more occasions than I care to remember, a queue would form of say four or five cars stuck behind a slowish car in the middle of an overtaking maneuver. Cars approaching the rear of the queue would dart down the inside of the queue cutting in at the front (with no indicators of course) causing everybody already in the queue to almost concertina into one another under braking.

I suppose the best advice I can give is to make sure your tyres and brakes are in excellent condition before driving in Germany!!

It's not all doom and gloom though, not having to worry about what speed your doing is so relaxing, you can simply concentrate on the actual driving and are far more aware of what's going on around you rather than constantly checking the speedometer. I also believe that the majority of people drive within their own and their cars ability.

(**) Loads must never be exceeded, the driver must arrange the goods in the luggage compartment and/or load surface in sush a way as to respect these limits.

The fuel consumption values listed in the table above were determined in offical tests utilizing procedures defined in EEC directives. Simulated city driving fuel consumption is measured on a test bed while constand speed (90 and 120 km/h) fuel economy is measured on a dry, level test track and using test bed procedures. These values may be useful for comparing different vehicles. Actual fuel consumption might be slightly different from offical values due to traffic conditions, driving style, weather and the car's general condition.


TYRE PRESSURES

The following table shows the correct tyre pressures in bar and psi. The pressures in bar are from the Tipo Manual and I have calculated the psi figures based on 1 bar = 14.5 psi. Remember to check the values when the tyres are cold.

I use 2.5 bar in the front and 2.2 bar in the rear and all sets of tyres I have fitted have worn perfectly evenly. I check the tyre pressures every 1 - 2 weeks

The spare is a 115×70 R15 space saver. Never exceed 80 km/h whilst it is fitted. It has a maximum life of 3,000 km. Never use two spares on the car at the same time.
