SEAB - Sociedade de Engenharia Automobilística Brasileira

Sociedade de Engenharia Automobilística Brasileira

SEAB or Sociedade de Engenharia Automobilística Brasileira (Brazilian Automotive Engineering Society) is an engineering group turned car maker in the mid-50s. The group’s existence traces back to the first engineers with automotive knowledge to migrate from Europe in the late 19th century. Their existence is known through modifications and one-offs based on imported cars from Europe and the USA prior to WWI. Their badge is a flying bat, as the first slang for the group of engineers, that worked on their automotive endeavours through the night, after the day job was done, was “Atelier Morcego” (Bat Workshop).


After the war, the Brasmotors group, a fairly big automobile importer, decided to bring the newly released Leutewagen sedan, along with importing parts packs for small manufacturers. SEAB took this opportunity in 1955 to release its first, full in house built car, after a good amount of years uselessly building military vehicles for the Brazilian army, never being used in combat as the country never took part in the wars. The SEAB Onça was a fiberglass-bodied coupé, powered by an Leutewagen 1300 boxer engine, though a 4-speed transaxle. The car’s frame was a custom made, square tube frame, with a bespoke (for the time) 4 wheel independent suspension, along with custom axles to convert the swing axles to IRS. The engine also received custom water-cooled heads and a better carburetor. The works started in 1953, using parts from a newly imported Leutewagen, during the arrangements to import the parts, and the design was based on revamped pre-war drawings, so the car could hit the market as soon as possible. The car was a hit, being sportier than its donor due to being lighter and looking way better. The price tag was high due to its handmade nature, but with the country’s situation normalizing after the war, the medium and high class were ready and eager to have new sports cars. The car was built until 1958. In 1957, Einvagen opened their own factory in Brazil and stopped selling parts to third-party builders, as a way to push their car to the masses


Since the forced end of production of the first model, and the last cars built using parts in stock in 1958, SEAB searched for a way to maintain themselves on the market, and that opportunity came when they discovered that Cherrier, a french brand that was pushing to enter the Brazilian market, were being held off by Leutewagen’s “executives”. After a trip to France, a deal was arranged. Cherrier would provide inline 4 and 6 cylinder engines to keep the Onça in the market for a little while, along with a facelift, until the co-developed Amazonas/Tikuna lineup was ready to launch. The two utilitarian vehicles were a hit, on a country in desperate need of workhorses to keep up with this brand new world’s evolution, and the money earned, plus the partnership with Cherrier, allowed for the development of a new line of civilian cars. In 62, the Arara was born, utilizing the same I4 used in the second run of the Onça, on a sleeker and more spacious body.

Following decades coming soon.

This thread is “Good end” lore compliant, as there’s no point in creating a RL compliant brazilian car manufacturer, as our car history is exceedingly boring, and is being developed by the members of the brazilian Automation Discord. We’ll be writing and posting more lore about it in the next days, so stay tuned!

1955 - 58 SEAB Onça MK1

This was SEAB’s first car that wasn’t a modified special over other brand’s chassis. It’s powered by a Einvagen 1300cc aircooled boxer engine, modified with water cooled heads and better carbs, though a 4 speed transaxle. It have a handmade square tube frame, and a fiberglass coupé body. The suspension is an in house developed independend setup, uncommon on street cars of the era, and expensive to build. It was the first appearance of SEAB’s bat badge, a symbol of engeneering passion, as most of the brand’s employers had other jobs during the day, and worked on the cars during the night on it’s first years of existence.

I get a Lotus Cortina vibe with this one. Only cuter :heart_eyes:

And its color scheme not only pre-dates the Lotus Cortina by several years, but features a brighter shade of green to boot, which makes it even more striking.

Actually, I think this car was an inspiration for the creation of Pokemon. Onca-chu I choose you!

1960 - SEAB Amazonas and Tikuna line-up

The new co-developed cars are the Amazonas and Tikuna, a mid-size SUV and a Pickup, respectively. SEAB used in both models the inline 6 cylinder engine, serial number I6SEAB57, provided by the french brand Cherrier. The Amazonas came with the 98HP, 2200cc engine, coupled with a 3 gear manual. The pickup truck came with a 3000cc model, a relatively large engine for its size, developing 150hp through a 4 gear manual transmission to the rear wheels

The Amazona was developed to fill a gap in the market where people wanted a capable family car with better comfort and power than the competition. It was available in various color options and a premium interior in beautiful White Leather, with an optional AM Radio with high-fi speakers for ₢$12.900. (96.2 KB)

As for the Tikuna though, it was engineered to dominate the fleet market with all of its power and load capacity. The first midsize pickup truck that could push 1780Kg of cargo in its bed at the time. The Tikuna was available in fleet minded color options, with the odd option from the Amazonas lineup, and a basic, but the well-made interior, for ₢$12.500. (108.6 KB)

1959 - 61(2) SEAB Onça MK2

After Einvagen broke the parts deal with SEAB, the french Manufacturer Cherrier provided a 1600cc I4 engine, plus a similar 4-speed transaxle, to keep the Onça on the market for some more years. A facelift was also due, which included a more refined front and rear clip, with horizontal elements somehow working together with the pointy and vertical rear shape. The bumpers were simplified, and the lights were changed to wrap around units. On the interior, the Onça got a simpler interior and finishing, as the resource focus was being directed for the new passenger lineup being co-developed with Cherrier. The MK2 Onça stayed available until 1961 when the new passenger lineup replaced it. The last units were built in February 1962 and were sold as stock cleaning with a limited range of colors and a single standard trim level. These last units were mostly cleared by amateur racing teams looking for sharp driving dynamics on a tight budget. The fiberglass body was never made to withstand much abuse, but the heavy-duty tubular frame kept the car in running condition during heavy rallying and was easy to weld a roll cage to, making it reasonably safe for the time. It was the first production car, and the last handmade project from the group for a long while, ending an almost 30-year-old tradition of one-off specials. (72.4 KB)

1962 - Arara Line-up

In 1962, with the end of Onça production and the sales of its SUV and pickup truck breaking records since its launch the company decided to make a big decision. Launch a line of cars aimed at a low-budget family market.

Then the Arara line was born.

2.4m wheelbase cars, 1600cc engine that until the end of its production was used in the Onça but with some adjustments, you can have a less powerful engine (71HP) more economical and quieter for normal use. Longitudinal front-engine, RWD, and manual transmission in all variants. Ladder chassis made of steel and steel panels as well.

Arara Especial
5 seats with no much space for the 5 occupants. Start price of ₢$9770 (49.3 KB)

Arara Família

The wagon version of Arara. This would be more for a short trip, even because this one doesn’t have the same comfort as its bigger cousin. Red interior with you had bought the red exterior. Available for ₢$9570(Amazonas) (52.0 KB)

Arara Luxo
The Premium Compact Sedan for landowners who want comfort, but don't want something big like the Amazonas. Price of ₢$13300 (57.3 KB)

1972 - Arara Mk2 Line-up

In 1972, SEAB decided to refurbish the Arara model. Without a facelift since 1966 (some small changes in the engine to make it more economical) they presented the Brazilian Market with a brand new visual, body, and some major changes to the i4SEAB57 engine. Now we have 3 different variants and one Special Edition, come along to this post to know more.

2.5m wheelbase cars, 1600cc and 1800cc engines (1600E; 1800E and 1800S) that were used in the previous Arara with some little changes. The ‘E’ letter stands for ‘Economical’ and the ‘S’ for Sport.
Longitudinal front-engine, RWD, and manual transmission in all variants. Ladder chassis made of steel and steel panels as well.

Arara Especial
Comparing to the old version now you have leg room for the back occupants. This variant come with the '1600E' (77HP and 112nm of torque) engine variant or the '1800E'. Available in the 'Brasilia Yellow' and 'Turquesa Aquarius' colors. Starting price at ₢$9700

Arara Família

The wagon version of Arara focused on the small family business that just wants a big economical car to make medium trips. It has the ‘1800E’ (87HP and 127nm of torque) variant to make it easy to carry luggage without losing performance. But if you want you can choose the cheaper version (1600E). Available in the same colors as the Especial version. Starting price at ₢$9810

Arara Luxo
The Premium Compact Sedan for the Brazilian businessman who wants some comfort, but nothing as big and old as the Amazonas. With so much comfort the car becomes heavier, so SEAB decided to put the same engine as the Familia version to not lose performance. 'Celosia Claro' and 'Celosia Escuro' colors. Available at the Starting price of ₢$13300

Arara S/R
The first coupe version is light sport one. It's no up to the buyers to choose the 1600E variant on this one, instead you can only have one: the 1800S (107HP and 141nm of torque).

This engine variant helps the Arara to reach 181km/h and do a 0 - 100 in 10s. SEAB reworked the suspension made it harder, so the S/R can do some cornering easier. And of course, it has an integral disc brakes system. The ‘Vermelho Nascente’ is the only color you can choose for this variant.
Starting price at ₢$13500

Arara SS/R (Limited Edition)
If the performance numbers of the S/R version didn't catch you up, SEAB announced an ultimate Sport variant, and it is breathtaking.

They take the i6SEAB57 engine from the old Amazonas, update it, and put it in the Arara S/R. But it doesn’t end there, they have gone far.
The ‘2200S’ is a total updated engine with a little performance tune and now it’s capable of doing 133HP and 180nm of torque. The suspension again has been reworked and the cornering in a 20m radius is 1.01g allied with some big alloy wheels and sport tires gave the SS/R an incredible performance numbers.

The changes are phenomenal. Now you can have 195km/h of top speed and a 0 - 100 in 8.7s.
Of course, it isn’t a mass-production car, you can only order this version.
The CEO of SEAB said if this variant becomes an extremely desirable car, they will change the way of selling it.
SS/R Version is available only in ‘Verde Igarapé’ color and you can order for ₢$17600 (71.2 KB) (73.4 KB) (76.8 KB) (74.7 KB) (76.8 KB)

1994 - 98 SEAB Guará MK1

Jumping some decades in SEAB’s history, we have a subcompact that was developed as a solution for cheap city transportation and fleet business in the tight, colonial reminiscent streets of Brazil’s metropolis. Its cheap materials and basic engineering weren’t of much praise, nor the 1000cc 85 hp engine. Its single noticeable feature was the ability to reach 10000 rpm, through peak power is reached at 8800. Perks of the Japanese technology available, as the military lockdown never happened in this timeline. (48.9 KB)

1973 - Amazonas and Tikuna

In 1973 one year after the release of the Arara, SEAB announced that they were coming to launch a new facelift for the Amazonas and Tikuna.
The company saw that a car being 13 years in the market without any facelift was a suicide after the Arara’s being the most vehicle ever sold in the Brazil until then.

The visual in the front was reworked for both of the variants. The interior was now all in black and the exterior colors was all the same present in the Arara’s line-up. Except for the ‘Verde Betim’ and ‘Prata Tibet’ those were exclusive. (respectively in the picture above)

Amazonas SUV

The SUV version was using the same engine as the previous version, but with a little more technology. You can have more power (103HP) and fuel efficiency.

It became more luxurious with one speaker in each door, the Premium AM Radio from ‘Blaupunkt’ was the highlight of the version. Thanks to the manual 4 gear drivetrain you can have more economy.
The starting price was at ₢$14.500


The pick-up truck was no more available with the 3000cc engine instead the 2800cc version was capable of doing the job that it was meant to be.

For the review, we don’t have a lot to talk about this one, since the SEAB didn’t change it too much.
But we have an opinion to make, why they did the 2800cc version? I think we will don’t have the answer to that.

These two vehicles were produced and sold until 1976, when SEAB decided to end up its production due to low sales. (101.1 KB) (105.6 KB)

1976 - Arara Mk2 S/R Bi-albero (Prototype)

In 1976 at the ‘Salão do Automóvel de São Paulo’, the biggest car exposition in Brazil, SEAB introduced the Arara prototype, which was released four years ago. And for the first time the model receive a possible ‘facelift’.
They came with the S/R Version but a lot more focused on the race and track segment.

It was the same car but with a refurbished visual to look more aggressive. They decided to keep the i4 engine but with 30 horsepower more than the standard S/R. The quarter-mile of 15.78 seconds was faster than the SS/R version and its 0 - 100 performance has almost a second of difference.

According to the press, the engine was reworked so it could make more than 140HP in a 1.8L i4. And of course, the DOHC wasn’t enough, this prototype came with dual DCOE Carburetors, piston and conrods forged.
It was clear that SEAB was trying to tell that they can make some real cars, capable of being better than ever.

This one, of course, wasn’t available for sale.

1995 SEAB Terena

This light sports car was produced by SEAB around the turn of the century, sporting a rear-mounted 1.6 engine with 8 or 16 valves on an under-tonne chassis. Car by @AlexLzn03

8S - 1.6l 8v - 94hp/135,5nm - 9,5s 0-100 km/h, 213 km/h top speed
16S - 1.6l 16v VVL - 110hp/144nm - 8,7s 0-100 km/h, 222 km/h top speed


The Terena may not look very different from a post-facelift Foxbody Mustang, albeit shrunken and rear-engined, but it still looks the part, and even the less powerful 1.6L I4 should prove sufficient for its light weight.

1968 - 74 SEAB Manaus MK1

Alongside the more premium Arara, SEAB started offering the cheaper Manaus as a way of catering to a broader consumer base, something the brand hadn’t tried yet, even though the Onça could be considered a popular-sized car, its handmade nature made it expensive to produce. The Manaus was offered in 3 versions, the frugal Special, premium trimmed Deluxe, and the “sporty” GT, all of them powered by an archaic 1300cc i4 engine whose build plans were part of the agreement with Cherrier, it’s an outgoing engine in France, but it still packed enough punch to be a mass-market success, even threatening Leutewagen’s sales, which led to an unholy agreement some years ahead…
Plus, it had a weird longitudinal fwd layout, with the engine entirely ahead of the front axle, and universal joints instead of homocynetics in the first years, which tended to self-destruct on certain speeds and loads due to harmonic vibration. Car made by @IMC_The_Drunk_BR
