Dutch Man Builds Alfa Romeo GTV Bi-Motore with Two V6 Engines and 487HP [with Videos]


“What do you do when the power of an engine is no longer sufficient?” asks Stephan Lenior, the man behind Squadra Tuning, on his company’s website. While the solution for the majority would have been a heavily modified or perhaps a completely different engine altogether, for the owner of the Alfa Romeo tuning company based in Holland, the answer to that question was far more radical and complex.

To make a very long story short, Stephan’s solution to u the performance of his Alfa Romeo GTV V6 involved the fitment of a second six-cylinder engine at the back. Easier said than done of course, with the project turning out to be a rather complicated and time-consuming process.

Stephan documented the entire build on his company’s website and if our Google’s translation is correct (any help from our Dutch speaking readers would be appreciated, especially on the matter of the transmission), Stephan took a 3.2-liter V6 along with the sub frame and suspension bits from an Alfa Romeo 166 and placed them in the rear section of the Italian coupe. Together with the GTV’s front-mounted 3.0-liter V6, the two engines produce a combined output of 487-horsepower.

We are not entirely sure on this one, but it appears that the GTV is equipped with two 5-speed gearboxes, both sourced from a Lancia Kappa 2.4 JTD, and controlled by a single gear shifter.

The car also features a set of front disc brakes from the 166 mounted at the back, while the builder tried to compensate for the increased weight of the second powertrain by replacing certain components such as the powered seats and standard alloys with lighter equivalents, and removing unnecessary amenities like the air-condition and sound insulation.

Surprisingly, Stephan kept the GTV’s exterior look stock with the only telling feature about the build being the air vents on the boot.

The owner claims that the Alfa Romeo GTV Bi-Motore can accelerate from zero to 100km/h (62mph) in about 4.5 seconds and to 200km/h (124mph) in approximately 14 seconds, while theoretically topping out at around 290km/h (180mph), though for obvious reasons, Stephan has not yet tried to push the car -and his luck- to the limit.

Yeah...what he said. All joking aside, this is one nice sleeper. America, set aside your TV remotes, your game controllers, your stupid iPads where you're only playing games, and get to know what STEM means; then indulge in it.

He speak English or his own language ? :\
Some moment of the video sounds like English but some not .

Anyway , that's seriously a sleeper ... a Alfa with 2x 3.0-liter V6 , could be count as 6.0-liter V12 already .

Anyway , too bad there seems like no where to start only one of the 2 engine .

How does this thing work? The engines are transverse, how did he connect the drive train? What about the transmission? etc. ?

It is not the first time a car is equipped with two engines.

As far as I remember there is at least one example of a 2-engines model developped in-house officially by a car maker (I am talking about the SEAT brand which in the '80s had developped and taken part in tracks with an official race car (SEAT Panda model) with two engines).

we here in Croatia have a man who built a vw lupo with two vw 2.8L 24v v6 engines,custom rollcage,front brakes from a porsche cayenne,rears from an audi rs2 with g4 r32 discs,18" oz ultra's, 200hp of nitrous,and a bi-turbo kit for each of the engines is in plan...

here are the vids to prove it :)

and almost the whole project in pics:

Not the first time this has been done as stated before. Car and Driver magazine, under the watchful eye of MIT-trained engineer turned magazine editor Csaba Csere, build a twin engined Honda CRX in the 80s. If memory serves, the title of the article was something like "Hubba Hubba Honda Honda". He specifically addressed the coordinated shifting of the dual transmissions.

Pretty toit for a fricking Dutch bashtard! Aushhtin Powazh would love dish car.

I saw an Audi TT done out with 2 engines. Possibly easier done in that case as it was already a 4WD platform?

Anyway cool stuff. My old man wants to put two engines in a Renault 4L.

This is dutch language and it's not the same as one 6 litre. Think about the weight balance and the power distribution...
