Authié et Dallier

Authié et Dallier is a belgian low series manufacturer of mostly exclusive sports cars, more info is coming when I bother to write something up, which, as you know, can take some time… :roll_eyes:



With the introduction of the 1984 6/26, many purists were fearing that the brand was becoming too mainstream. Truth is, the almost bankrupt manufacturer needed something that was more of a volume seller in a market that had taken a hit from, for example, the energy crisis and evolving safety and emissions regulations that had plagued the 70s.

To lower the price somewhat, the 6/26 was the first model from the belgian manufacturer that featured some panels made of steel instead of the all aluminium bodies of all its predecessors.

Of course, “mainstream” should be taken in its context. Of course the 6/26 featured some rather advanced technology, like double wishbone suspension and vented disc brakes all around, as well as an interior where 4 people could ride surrounded by the finest leather and woodwork.

The 2.1 litre V6 was more or less half of an A&D V12, featuring an all aluminium construction with 18 valve SOHC heads. Two turbochargers bumped up the power output to 227 hp, meaning that the car accelerated to 100 km/h from a standstill in 5 seconds and kept accelerating until it reached 264 km/h.

Meaty sports compound tyres on genuine split wheels (albeit the centre lug nut was only a fake hubcap) topped everything off and was probably contributing to the great cornering abilities of the car.

When production ended in 1997, it had succeeded with its task, bumping up the sales volumes for a manufacturer that was encountering rough times.


This brings to mind a Belgian equivalent of the Maserati Biturbo (and, by extension, the AM336 Ghibli, as well as the V8-powered Shamal and 4th-gen Quattroporte, all of which were built on the same platform), albeit better executed. From what I’ve seen, it’s built on the smallest of the '78 W124-esque body sets (with a 2.55m wheelbase) - and it’s one of the better uses of that particular body set in that size.

Correct, it’s that body! :slight_smile:

And yeah, I aimed for a Biturbo competitor so seems like I have succeeded then.

1985: 6/26 SEDAN
1987: 6/26 CABRIOLET

The first spinoff from the 1984 6/26 Coupé was the sedan version that arrived in 1985. Never as popular as the coupé though, it was actually the first version to get a replacement already in 1994. The practicality was mostly added through the rear doors, sharing the roofline with the coupé and still being only a 4 seater, yet not as stylish, it was probably not seen as the best jack of all trades.

In 1987 a convertible was added to the lineup. Of course a low series vehicle that never reached any giant production figures, but it found its niche and was built alongside the coupé until 1997.



Even though the car pictured is a 2005 model, the 8/30 sedan was introduced in 2003.

At its release, it was not a direct successor to the outgoing 6/27 sedan. Instead, this was the return to the large luxury sedan segment for the company, after some years of hiatus.

Instead of the steel/alu panels that the 6/27 (and its predecessor, the 6/26 sedan) used, the 8/30 had all aluminium body panels (albeit with a steel structure), something that the brand puritans appreciated.

The engine was a 4.2 litre naturally aspirated V8 with a power output of 376 hp. That meant that with the 6 speed dual clutch transmission introduced for the 2005 model year, the car could accelerate from 0-100 km/h in 4.6 seconds, and had a top speed of 335 km/h.

A torsen differential and meaty 285 rear tyres helped to put all the power down to the ground. Vented discs filling up all the space in its large for the era 19 inch rims helped the car stop on a dime.

As usual for the brand, the car featured an interior with very nice woodwork and leather. Very few modern gizmos were missing, things like SatNav was standard equipment from the factory.

The 8/30 sedan was built until the 2012 model year.


Maserati: hold my frizzante

I can’t quite figure out the logic behind those X/YY designations - is YY just a consecutive project number or sth like that? X is cylinders, clearly, but the second part…

Those mirrors are a really nice detail, adding to the refined, dynamic vibe of the car. I like the complexity of the logo too, could we get a closer look at it?


It reminds me of the Quattroporte V - in fact, the best way to describe A&D as a whole is as a Belgian equivalent of Maserati. As for body choice, I’m assuming it was built on one of the '88 Indicator body sets - specifically, one of the larger ones (2.85m wheelbase or larger) - it’s too rounded for me to presume otherwise.


I just went simple. Number of cylinders / wheelbase rounded in decimeters :laughing:


For the 8/30, that means a V8 and a 3.0m wheelbase - the same size I used for the Ventnor V12.

Yep, so you were right about the body but it was the even larger variation.

Here is the badge up closer BTW.
