Michelotto Gruppo 4 Tributo: A 950 kg V8 Inspired by Ferrari Rally History

The Michelotto Gruppo 4 Tributo looks like a Ferrari 308 rally car and is built by a firm that has prepared real Ferrari racers for decades.

It is not a Ferrari. That distinction matters, and we will come back to it.

The reported recipe is lovely: a naturally aspirated V8, a manual gearbox with a dogleg first, and a claimed 950 kg.

There are also two number problems worth untangling, and one naming joke hiding in the engine size.

First, It Is Not an Official Ferrari

This needs saying before anything else, because the styling invites the assumption.

Ferrari is not building this car and has not endorsed it. It is a separate project, reported as a collaboration between Michelotto and AC Motorsport.

It is also not a restored original, and not a restomod in the usual sense. The reporting describes a ground-up build.

So treat the Ferrari 308 connection as inspiration and heritage, not provenance. The car is a tribute, which is exactly what its name says.

Who Michelotto Actually Are

This part is verifiable, and it is the strongest thing about the project.

Michelotto's own site says the company has operated in Padua since 1969, doing GT motorsport engineering and precision machining.

Its own description names the cars it has worked on. The Ferrari F40 LM, the Ferrari 333 SP and the Isotta Fraschini LMH.

Those are not decorative credentials. The F40 LM and the 333 SP are serious racing machinery, and Michelotto's name is genuinely attached to them.

It also works outside cars, in medical and aeronautical machining. This is an engineering company, not a styling house.

The 308 Rally Record Behind the Name

This is where the Michelotto Gruppo 4 Tributo differs from most retro tributes. The firm helped create the cars it is honouring.

By Michelotto's account it became an authorised Ferrari workshop in the 1970s. It then developed the Ferrari 308 GTB Group 4 for rallying.

The wins claimed for those cars include the Targa Florio, the Tour de France and the Rally di Monza. Eleven Group 4 examples were built, followed by a few Group B cars as the rules changed.

The result that gets quoted most is the 1982 Tour de Corse. Jean-Claude Andruet finished second there in a Michelotto-prepared 308 GTB.

That is described as Ferrari's only World Rally Championship podium. It is a striking claim, and worth marking as a claim.

We could not check it against an official Ferrari source. Ferrari's own article on its rally years blocks automated access, so we read none of it.

Michelotto is also credited with work on the 288 GTO and F40 competition programmes. That is five decades of Ferrari race cars, not a weekend hobby.

One number is worth holding onto. The original run was eleven cars. If the Tributo follows that scale, it will be very rare, though no build figure has been announced.

But the Company's Own Site Does Not Mention the Car

We went looking for an official specification and found none.

The Gruppo 4 Tributo does not appear on Michelotto's website. Neither does AC Motorsport, nor any price or production figure.

There is a further curiosity. The site lists the F40 LM and 333 SP among its work, but not the Ferrari 308 Group 4 rally programme.

That is odd for a firm now selling a 308 tribute. The rally programme is the whole basis of the car, yet the company's shop window skips it.

The site shows only a short summary of a long history, so this may be editing rather than anything meaningful.

So everything technical below comes from press coverage. None of it is a manufacturer specification yet.

The Reported Specification

Here is what has been reported, with the units stated properly.

Figures from press reporting rather than a manufacturer sheet. The specific output is our own arithmetic.

How the Car Is Reportedly Built

The construction explains the weight claim, so it is worth a paragraph of its own.

Reports describe a tubular frame with the roll cage built into it. Carbon-composite panels then go over that frame.

That is a race-car structure rather than a production one. It is also the normal way to get a sports car under a tonne.

The panels are shaped like the wide-arched 308 GTB rally cars. The low wedge profile is there, and so are the pop-up headlights.

There is one thing the Group 4 looks do not tell you. The car is reported as built for tarmac, not for gravel stages.

So the rally appearance is the styling brief, not the engineering brief. Michelotto appears to have kept the parts people remember and left the rest.

A fair caution follows from all this. A tube-frame car is not engineered the way a modern road car is.

No safety or homologation detail has been published for the Tributo at all. That is worth knowing before anyone calls it a road car.

That 380 Is CV, Not hp

You will see the figure written as 380 hp. That is not quite what the Italian coverage says.

The original wording is 380 cavalli. Cavalli means CV, which is metric horsepower, also written PS.

Metric horsepower is slightly smaller than the mechanical kind. 380 CV works out at about 375 mechanical hp.

So the English figure overstates it by roughly five horsepower. Not much, but it is the sort of slip that compounds across a spec sheet.

This is a common problem with Italian, German and Chinese figures. When a number looks suspiciously round, check which horsepower it is.

Why "400 Per Tonne" Only Works in Metric

Do the power-to-weight sum and something tidy appears.

380 CV divided by 0.950 tonnes is exactly 400 CV per tonne. A beautifully round number.

Convert to mechanical horsepower and it becomes about 394 hp per tonne instead.

That is still a remarkable figure for a road car with a naturally aspirated engine and no electric assistance.

But it explains why you will see 400 quoted without a unit attached. The round number is a metric one.

By Ferrari's Own Logic, This Is a 348

Here is a detail for anyone who enjoys Ferrari's old naming system.

In that convention the first two digits gave the engine size in decilitres, and the last digit gave the cylinder count.

So 308 meant three litres and eight cylinders. The real engine measured 2,926 cc.

Now apply that rule to the Tributo's reported 3.4-litre V8. Three point four litres with eight cylinders would be a 348.

And Ferrari built one. The 348 ran a 3,405 cc V8, which is almost exactly the size reported here.

So this tribute to a 308 carries 348 displacement. A pleasing accident, and a reminder that the name is about the look, not the engine.

The Weight Matters More Than the Power

If the 950 kg claim holds, that is the headline rather than the engine.

Modern sports cars have grown heavy. Airbags, crash structures, infotainment and sound deadening all add mass.

Weight hurts everything at once. Braking, turning, tyre wear, fuel use and the feel of the steering.

So a car under a tonne behaves differently from a heavier one with the same power. It changes direction rather than negotiating.

One caution on the figure. A claimed weight is usually a dry or best-case number, and nobody has said which this is.

The Dogleg Gearbox Is the Real Statement

A five-speed manual in 2026 is unusual enough. The dogleg pattern says more.

In a dogleg box, first gear sits down and to the left, outside the main H. Second to fifth then form the familiar pattern.

The point is that second and third sit in a straight line, which is the change you make most often on a circuit.

It is awkward in traffic and quick on a racetrack. That tells you what the car is for.

It also places the Tributo in a small revival. Several makers have brought manual gearboxes back for drivers who want to be involved rather than assisted.

Put it next to a current Ferrari and the gap is stark. The 296 GTB is a plug-in hybrid with a dual-clutch gearbox and layers of electronic control.

That car is faster in almost any measurable way. It is also heavier, more complex and far more insulated from the driver.

The Tributo is a deliberate refusal of that direction. No turbocharger, no hybrid system, no dual clutch — and that is the whole argument it is making.

Price and Numbers: Nothing Announced

We have no price for you, and we are not going to estimate one.

No official price has been announced, and no production run has been confirmed.

For a hand-built car from a motorsport engineering firm, expect a small number of examples. That is a reasonable assumption rather than information.

Needless to say, there is no Pakistan availability, and there will not be. This is a European project built in tiny volumes.
