For the record I’ve been waiting to do this post for literally two months. So:
1981 through 1986 - AWD and Group B tales: The FAAL Tetra
It’s been three years since FAAL’s comeback in the sport car market, and people couldn’t rejoice more. From the affordable and kart-like Plebia S to the german-tickling Mesaia GTI all the way to the tail happy Coupe Turbo, any wallet in need of sensations could find its weapon of choice. If sales were only good, the brand image was starting to rise up to a whole new level… which was the goal the Klinos failed to achieve. Luxury wasn’t the way to go.
But now… you don’t build sports cars just for the heck of it, do you? Oh no. Competition is where it’s at. And for that, the Coupe will have to up its game.
1981-1982 Coupe TETRA - Evo 1
TETRA. A word that will surely make the ink flow as the very first French permanent AWD system ever made.
Now, why so much craziness, in an age where every single car made in France is transverse, FWD and 4 cylinder? Simple.
FAAL had been taking a gamble three years ago by making the Coupe RWD, taking lessons from the Germans. It was either going to be hit or miss. And, as it turns out… Hit. People were so glad to have a car that was RWD, and a very well handling RWD on top of that, that they didn’t care about the lack of power and the desperately low redline from the engine. So why not take it to the next level? Taking lessons from the germans again it is.
So the Coupe was for the second time the advertisement car of that glorious drivetrain layout, and the car had been revised for the occasion. TETRA-only design changes include:
- A one bar grille instead of three bar, body painted
- One piece bumpers, body painted
- Delightfully 80s box flared wheel arches
- A plastic wing, replacing the simple spoiler of the Turbo version
- Appropriate TETRA badging instead of COUPE
- The FAAL front badge was moved to the left side in an attempt to tweak the design enough to distinguish the car from a regular Coupe even more
The 50/50 AWD system made the car gain weight, at 1147kg, or 80kg more than a regular Coupe Turbo, and as a result, to extract significantly better performance out of the Tetra, the engine had to be upgraded.
The Coupe’s 236S23MTE engine saw a brand new ball bearing turbo and ditched the hypereutectic cast pistons for tough, forged ones (rendering the car unsellable in the US because of that), and the new 236S23MT now made 175hp and 264nm peak, a 20hp and more than 30nm improvement over the Coupe’s engine, not to mention the raised redline and lower peak torque.
With accurate tuning of the 5 speed that could now accept lower first gears, the Coupe TETRA Evo 1 went from 0 to 60 in 7.1s (1s improvement over the Turbo, and no wheel spin at all) but retained the same 200km/h top speed as the Turbo.
So far, the car was already incredibly more driveable than the standard Turbo Coupe, but the numbers felt like wet fireworks being lit. BUT THEN:
1982-1983 Coupe TETRA - Evo 2
During the one year of Evo 1 sales, FAAL’s engineers figured out “Hey, why don’t we combine the o2 sensor boi of the Plebia S and the multipoint layout of our mechanical injection in a multipoint EFI layout?”
As usual when someone makes such a discovery at FAAL, the whole team of executives got drunk beyond decency and wake up three days later after yet another alsacien booze shortage. This was no exception since their newest and last version of the now 17 years old 236S23 engine, the 236S23Mpi, made 23hp and 31nm more than its Mechanical Injection equivalent. With 198hp, 295nm and only 8 more kg than the Evo 1, the Coupe Tetra evo 2 now went from 0-60 in 6.43s and had a top speed of 208km/h.
The front fascia had been revised for the occasion, with a new hood scoop and a wider lower grille. The upper grille stayed the same; despite what the photo mode wants you to make believe, it isn’t blank.
Now the car was starting to feel great. More power, better throttle response, better stats overall and on top of that, better fuel consumption. The Evo 1 kept being sold for a while longer though, to give people more opportunities because the new engine only ran on 95 octane.
It looked like things couldn’t get any better BUT THEY DID.
1983-19?? Coupe TETRA Evo 3 (+ Facelift)
1983 saw the now 5 years old Coupe’s mid career facelift, and with that, the arrival of the successor of the 236S engine series: The 256R.
This new block had a modern 24 valve layout all cramped on the same camshaft and was designed to run with multipoint EFI in the first place. Better air flow. Higher redlines. Lower service costs (though they’re already stupid high for turbo Coupes :t). The engine was also designed to be stoked to 2.5L (though with a very high stroke/bore ratio), but the one that found its way in the Evo 3 was a 2141cc slightly undersquare turbo unit. Why such an odd displacement? We’ll get to it later.
Of course, it’s a Facelift, so instead of listing all the physical changes I’ll let the pictures speak because we’re barely halfway through yet:
The new engine, the 256R21MpiT, had a slightly worse torque than the outgoing one (292nm), BUT more power, 215hp at a high 6600RPM, which made the Tetra Evo 3 a car that you WANT to bring to the redline. Also, first FAAL engine to reach 100hp/L. Traction was starting to show its limit though, and that’s why the TETRA system was updated too, with brand new geared LSDs front and rear, the whole package allowing a 0-60 time slightly below 6 seconds and a top speed of 215km/h.
Of course the regular Coupe also saw the Facelift as well as new 256R derived engines:
The base model is now the 2.1CS, with a
256R21Mpi engine making 126hp or 11 more than the outgoing model…
The Turbo model now has the 256R21MpiTE engine making 180hp or 25 more than the outgoing model and even crazier, 5 more than the Tetra evo 1. Talk about progress.
It keeps getting better and OH MY GOD WHAT IS THIS.
1983-1984 FAAL Tetra Tour De Corse (Group B homologation special)
Of course, FAAL wouldn’t dump crazy amount of money in R&D if they didn’t want something out of it, and competition had been their goal from the very start. Their AWD TETRA system was ready and tested out on road cars by buyers who didn’t even know what was about to hit them just like Group B drivers.
Now, to participate in Group B, FAAL had to build a homologation special. 200 road cars that are close enough to the competition car, but still actually sell in the real world. Which is, in fact, why their new engine has such an odd displacement that allowed it to participate in the 3000cc category. Peugeot did it. Audi did it. Lancia did it. It was their turn. Here comes the TETRA Tour De Corse.
The TETRA Evo 3 had seen everything that wasn’t necessary taken off. Stereo, rear seats, extra cladding and unnecessary safety amenities all gone. Despite that, the Tour De Corse only shed 48kgs compared to the Tetra Evo 3 because of the stiffened chassis and wider tyres. The
256R21T2, though, now had an unreasonable 275hp and 330nm, allowing for a 0-60 tome of 4.7s, a 233km/h top speed and a quarter mile done in 13.27s.
The car was highly track focused, with stiff suspension, 235mm wide tyres and virtually nothing but a wheel, pedals, seats, and a crapton of power.
Of course, it only found home in the garages of the most dedicated FAAL enthusiasts and are now highly sought after cars, provided you can find one that is not a replica.
AND IF YOU THINK THIS IS PEAK 80s FAAL WAIT UNTIL YOU SEE THE ACTUAL RACE VERSION
The Group B FAAL Tetra saw two versions: The 1984-1985 season version had the 256R21MpiTR-F1 race only engine making 417hp out of a stock block, and the very last, widow maker 256R21MpiTR-F2 engine for the 1985-1986 season made 557hp with a revised head and tougher internals.
The car was relatively succesfull in competition… and by that I mean almost nobody died in it. As for actual racing pedigree, I think we’re gonna wait for the BeamNG exporter release for that.
TL;DR: Competition is a drug and that was one helluva long post.
