At launch, the engines were as follows : 1600 (1570cc,110bhp),
1800 (1779cc,120bhp) and 2000 (1962cc,128bhp) four cylinder units with carburettors, a 2500 fuel injection V6 in the Green Cloverleaf version
(2492cc,156bhp) and a 2.0 turbo diesel (1995cc,95bhp).
In the following year, 1986, the Alfa 75 turbo was introduced. This had the
1779cc twin cam fitted In 1987 the venerable old twin-cam was
redesigned to incorporate two spark plugs per cylinder (as Alfa had done
in the past in various race engines) and the twin-spark was born. The 75 got the 2.0 version of this engine,
which gave a healthy 148bhp, thanks also to variable valve timing and fuel injection. At the same time, Alfa released the 3.0i V6 America. Visually recognisable due
to the black side stripes being body coloured, it introduced the 186bhp 3-litre version of the V6 into the 75 and
was aimed at the US market, incorporating different front and rear bumpers to meet that country's legislation.
1988 saw the engines again changing, as the old carburettor fed 1800 was replaced by the 1.8IE and a new 2.4-litre turbo diesel joined the range.
The 1.8IE produced the same power as the earlier version, but the Bosch Motronic fuel injection and variable valve timing enabled a better torque curve
Late 1989 / early 1990 saw a 1.6IE joining the range (the carburettor 1.6 soldiered on for a while longer too) with 105bhp, whilst catalysed versions of 2.0 Twin
Spark and 3.0 V6 also emerged, both suffering minor decreases in power output. Slightly later in 1990 the 1.8 Turbo America was relaunched as the 1.8 Turbo Quadrifoglio,
gaining 10bhp (now 165bhp). The 3.0i V6 also gained 12bhp (up from a catalysed 180bhp to 192bhp) thanks to a new injection system, new camshafts and a new
exhaust system. Both cars received revised suspension settings to handle the extra power.
The Alfa 75 was well known for its quirky looks from the outside, and some unusual design features inside, such as the
U-shaped handbrake, the electric window switches in the roof....
Alfa Romeo never built a coupe version of the 75, but the SZ/RZ almost fulfilled that
brief..... See also our Alfa Romeo Concept
Cars page for the Zender Progetto Cinque spider based on the 75. In 1986 Rayton Fissore showed their interpretation of a 75 estate, called the
'Turbowagon'
(being based on the 1.8 turbo car). A pretty design, unfortunately it never made production.
Introduced
in May 1985, the Alfa 75 (or Milano in the USA), named to celebrate 75 years
of Alfa Romeo, was developed as a successor to the Giulietta/Alfetta,
and almost the entire mechanical basis was taken from the latter cars.
A mid size saloon the Alfa 75 continued the unusual Alfa Romeo design of having
the engine at the front and the gearbox at the rear to provide a good distribution
of the weight. Only ever produced in one bodystyle, a four door saloon
(drag coefficient 0.34), the Alfa 75 was the last car to use the Alfetta mechanicals.
with
a Garrett T3 turbocharger, fuel injection, intercooler and oil-cooler, producing 155bhp.
This engine was also developed for motorsport and gained some successes in a very short lived
career (including 3rd overall in the 1987 Tourist Trophy at Silverstone). The competition cars were heavily developed and included such changes as
coilover front suspension (replacing the torsion bars), outboard rear brakes and adjustable de dion rear suspension.
Aimed at both cashing in on the competition success of the 75 turbo, and
for homologation, was the 'Evoluzione', fitted with extra bodywork and a
luxurious interior and sold in small numbers.
to be produced. The 2.4 TD unit, a VM engine, came complete with KKK turbocharger and intercooler.
Aesthetically only very minor changes were made to these models, and various parts, such as the seats, were adopted from the Twin Spark.
The 75 was replaced in 1992 by the all new, front-wheel-drive 155.

Tuning
The brakes can be improved by using a higher specification fluid, fitting drilled
and grooved discs, using a superior pad compound and fitting stainless steel braided flexible hoses.
Dampers and springs are readily available
for the 75 which will improve the handling, and a strut brace can be fitted
at the front to increase the stiffness of the bodyshell. The rubber bushes can also be replaced by
items made from a less compliant material, such as nylon.
Easily
carried out modifications include installation of a free-flow air filter
(a cold air duct is also a worthy mod) and fitment of a less restrictive
exhaust system to improve the driveability, 'Chips' are also available
which (claim to) increase the power, driveability and torque all at the same time. More traditional methods such as carburettors and
camshafts will also work well with this engine, and there are plenty of experts around. Obviously the turbo engine is quite easy to
improve through increasing the boost, the charge cooling and the fuelling.
Buying / Selling
Some tips to do before selling :
(they may seem obvious, but most people don't do them and thus are in a weaker bargaining position)
If the car has been standing give it a
good run - this will clear out the engine (reduce exhaust smoke), put a
shine on the brake discs and loosen up any joints that may otherwise make some noises.
Jetwash under the car, especially under
the engine and in the wheelarches. The prospective buyer may be an enthusiast,
and this makes it easier for them to see what they want to check.
Even if you don't have a service history,
try to find any receipts, especially for the last timing belt change.
Obviously wash the car and clean the windows !
If you are going to buy a car always check the following :
Firstly check the bodywork. Check that
there are no mismatching panels, large areas of discolouration or signs
of fresh paint (compare inside the engine bay with the external body colour),
all of which probably indicate accident damage.
Check the brake pedal does not go to the
floor if pressed hard for a long time and if possible check the brake discs
for wear (the front ones through the wheels). Check the gearchange for clean engagement.
The engine should be run up to temperature,
check the exhaust for smoke, the condition of the breather (look for mayonnaise),
the condition of the oil filler cap (again white deposits can indicate head
gasket or other serious problems or the use of the car only on short journeys,
another bad state of affairs) and the colour of the coolant (preferably
not thick or dark brown!). Listen to the noise of the engine, then depress
the clutch and engage first gear. Whatever noise has disappeared was coming
from the gearbox, what remains is from the engine. Also check the condition
of the engine oil on the dipstick.The lighter brown the better, if it is thick black then leave quickly.
Check tyre wear, uneven patterns could imply a bent chassis.
Always take it for a test drive. Check
that the car tracks in a straight line with no steering input and also
remains straight under braking. Find a large open area and complete several
lock to lock turns (also in reverse), listening for any noises. Try the
handbrake when moving - seized rear callipers will mean uneven braking or no braking.
Tidy inside the car thoroughly : hoover
the floor, empty all pockets, ashtrays (wash), glove compartment etc...,
wipe the trim with a damp cloth, give the cockpit a good airing to get
rid of any odours ! Reset the trip meter to 00000 - it is a pleasant (subconcious) surprise.
Check the main electrical functions - wipers, windows, lights, etc... try putting
the main beam and wipers on at the same time. Check the headlights for
cracks and make sure that the air-conditioning unit works, if fitted.

A beauty, the last "real"
Alfa, with the driving wheels in the proper position (the rear). Great
acceleration and a wonderful throaty Alfa sound from the engine! (Patrizio C., Italy)
I have a 75 TS with only
82000 KM and it's been the best motoring experience I have ever had. (Carlos, Portugal)
A real sport saloon. Very fast and responsive. (Joe, Malta)
My 75 TS has done 276000km`s
and still going as well as ever. Engine only had oil changes/ tune ups/corosion
inhibitor changes. Proof of high quality engineering and regular servicing.
Brilliant car with the "grin factor" of a true Alfa. (Richard J, New Zealand.)
I love my 75 3.0 V6 Quadrifoglio Verde. Big respect and love to all Alfa 75 drivers. (Adiano, Switerland). Alfa 75 forever.
