Brazilian Ford F-250 short-bed with an aftermarket double-cab conversion

There were some versions of the Ford F-250 assembled exclusively in Brazil, with the regular cab matched to the short bed, with 3 engines that were never offered in the versions assembled in North America, such as the Essex 4.2L V6 from the F-150, the Cummins 4BT in a 141hp rating with a fully-mechanical injection system or 203hp with common-rail electronic injection, and the Brazilian-made MWM Sprint 6.07 TCA, all these engines backed by a 5-speed manual transmission and rear-wheel drive only. Before the introduction of double-cab versions in the local market in 2003, altough they were already locally-assembled for export to Australia including 4-wheel drive and other options such as the Triton 5.4L V8 gasser engine, the PowerStroke 7.3 and automatic transmission (standard with the Triton, and not available for the MWM engine), there were aftermarket conversions based in the regular cab. Some had the frame stretched to different extents, while other ones didn't, such as this one which also retained only 2 doors.

Is a 4-speed manual transmission really that bad?

In early 90's, it was reasonably well-accepted by American customers that some entry-level cars such as the 3rd-generation Nissan Sentra still had the option for a 4-speed manual transmission, altough the 5-speed ones were already available back then. In the particular case of the Sentra, in spite of the 5-speed versions getting rated by EPA as more fuel-efficient in highway at 35MPG while the 4-speed ones are rated at 33MPG, it`s not unusual for owners of the 4-speed versions to claim mileage figures not just above the EPA ratings, but also above the 5-speed versions.
The testing procedures defined by EPA are severely criticized for not being so accurate, and it may reflect on the current trend of wrong gear ratio selections which have been selected basically to get good EPA mileage figures instead of an overall efficiency in real-world conditions. Then, a 5-speed manual transmission with a higher ratioes at the lower gears could fare better at the tests than a 4-speed one with wider gaps among its gear ratioes, altough the 5-speed would require a lower differential ratio to retain some reasonable agility to start moving, therefore compromising the road performance altough the extra gear is supposed to compensate for that disadvantage. The weight difference might be considered negligible but, just like the slightly lesser amount of internal frictions at the transmission with one less gear, ended up favoring an increasement in the overall fuel-efficiency.

Another aspect to consider is an allegged "lazyness" of the average American driver who doesn't feel so pleased to shift gears manually, so a transmission with fewer gears to be shifted would be still prefered for those who would not want to pay the premium for an automatic in some random econobox like the old Hyundai Excel or when an automatic was not available at all such as in the Brazilian-made Volkswagen Fox.
On a sidenote, when the Fox export program started, Volkswagen of Brazil already had both a 5-speed manual and a 3-speed automatic available at the parts bin, but since the automatic wouldn't fit into the Fox without major structural mods it was ditched. Having to choose between the manuals, the 4-speed was favored not just due to the lesser hassle but also due to its improved fuel-efficiency, an important aspect to consider for a model which was offered as a budget alternative, and also because of its more precise shifting pattern compared, which would be more appreciated by drivers with little or no previous experience with manual transmissions. This very same manual 4-speed transmission was also used in the Brazilian Passat version developed for export to Iraq, since it was more resilient to abusive drivers than the 5-speed...

Another aspect to consider is the lower cost of manufacturing a 4-speed transmission. The 5th-generation Toyota Tercel had this option alongside a 5-speed manual and a 4-speed automatic, while the current Toyota Etios, specifically developed aiming 3rd-world markets such as Brazil, India and many African countries, has only a 5-speed manual. Well, considering that the Etios has an engine selection with outputs close to the ones used in the Tercel, it wouldn't be so strange if it had a cheaper 4-speed manual transmission too, mostly considering its budget-oriented concept.

Another point to think about is the "sporty" ideas associated with a manual transmission, regardless of how many gears it have. Or would anybody consider something like the Toyota Paseo as "sportier" than a Mercury Cougar Eliminator or a Shelby Cobra just because it has a 5th gear? I don't think so...

Nowadays we see 6-speed transmissions replacing the 5-speed ones as the mainstream option for those who still want a manual even in compact cars such as the Toyota Corolla and the Nissan Sentra, but they're again close-ratio and have to rely on a low differential gearing to provide some agility in urban traffic at the compromise of efficiency in highway traffic. So, considering other advantages and leaving the failed EPA test procedures behind, what would be so wrong in having a wide-ratio 4-speed manual with a higher differential instead?

The folks at EcoModder.com gonna like this Brink's van...

This cash-transit van from the Brazilian branch of Brink's has some features that, in spite of being kinda mainstream in South America such as the swamp-coolers on the roof, the 4-cylinder turbodiesel and the 5-speed manual transmission, are not so usual in their North American equivalents which usually rely either on a straight-6 or a V8 turbodiesel backed by an automatic transmission. The swamp-coolers instead of an air-conditioneer decrease the load over both the engine and electrical system, while the manual transmission is not just lighter but also has less internal frictions, thus not overheating so easily and increasing the overall efficiency. The lesser amount of heat to be exhausted also allows it to have smaller openings in the engine bay, decreasing the aerodynamic drag. The front grille is as small as the license plate, and is fitted between the 2 bumper-mounted auxiliary headlamps.

Cab-forward light-duty trucks: why not to give them a chance in the American market?

Around the world, the cab-forward (a.k.a. cabover or forward-control) layout have been far more popular not just in the medium-duty trucks market, they also became prevalent in light-duty operations due to the optimization of the platform lenght compared to a bonnet-nose truck, thus improving maneuverability in urban areas. A good comparison basis can be the Kia K2500 cabover and the Chevy S10.

EPA is usually the one to blame for the absence of some options to increase the overal efficiency of the American fleet, but the cab-forward trucks suffer due to the perception of these vehicles as "unsafe". Sure, there is a lack of impact crumple zones compared to a bonnetted truck, but if they were really so unsafe the NHTSA wouldn't ever allow this layout in the big rigs...
International 9800i: currently more popular in overseas markets actually

Hyundai HR: once it was available in Mexico rebadged as a Dodge
Some customers may think a cab-forward looks weaker, but it's not accurate. The cabin layout by itself won't prejudice the capacities, no wonder the Hyundai HR (a.k.a. Hyundai H-100, Hyundai Porter, or Dodge H-100) became one of the most popular options for car towing/wrecking in Brazil, since it can safely haul a midsize car.

Often, access to the engine for PMS purposes is pointed unfavorably to cab-forwards since they would either require the cab to tilt forward or an internal hatch under the front seats to reach the engine. But nowadays it's not really so unfavorable, since due to the engine getting mounted a little backwards even in conventional-cab trucks, it often requires the cab to be entirely removed on them to acess the engine or some specific components...

Another aspect to be considered is the availability of comfort features: nothing prevents a cab-forward to be fully-loaded, including options such as 4WD, automatic transmission and crew-cab, altough their main markets usually go for no-frills versions to be used essentially as a tool, while in America a whole cultural phenomenon developed around the usage of pickup-trucks as personal commuters, leading even to the introduction of luxury-oriented trucks such as the Cadillac Escalade EXT.

Usually, less attention is given to make the design of a cab-forward truck to look either "sporty" or macho rather than focusing only in the functional aspect, which seems to make this layout look less attractive for the average Joe who uses a truck just as an ego-extender, but nothing prevents either a redneck to haul all his guns, fishing rods and camping gear with one, or a ricer to turn it into a F-Truck racing replica.
After all, it seems that a cab-forward light-duty truck is a reasonable option even in the American market, it would only need a chance to find its chunk on the local market share.

Brazilian Fiat Fiorino MK3

Finally the 2nd-generation Fiat Fiorino got a replacement in Brazil and other regional markets such as Uruguay in late 2013. Altough its platfrm is the same one used in the Euro-spec Fiorino, also shared with the current Fiat Panda (including a Brazilian version introduced in 2010 but rebadged as Uno), the design still gets the same basic tall-box layout of the previous generation. There are also some differences in the powertrain options: it comes only with the 1.4L Fire Evo 8-valve engine in a flexfuel (gasoline/ethanol) version, bolted to a 5-speed manual transmission. Since it's mostly targetted to be a no-frills workhorse, a Dualogic automated-manual transmission is not available due to its purchase cost, in spite of the longer lasting of the clutch pack being a good advantage for a commercial vehicle. Diesel engines are also not offered for this variant of the Fiorino because its biggest markets (and basically the only ones where it's available), Brazil and Uruguay, have bureaucratic restrictions preventing the registration of vehicles with Diesel engines and a payload under one metric ton, unless they feature either hi-lo 4WD or at least seating for 9 passengers plus driver.

One of the most controversial among the entry-level motorcycles in Brazil, with a hate-it-or-love it design and the lack of many comfort and safety features such as electric start and front disc brakes not even as optional items, the Honda Pop 100 was introduced in late 2006, and is often pointed out as just a simplified version of the Super Cub series because of its backbone-tube frame layout and the engine slanted to the front.
Unlike the Super Cub, however, it doesn't have the underseat storage space, the scooter-like fairings and the automatic clutch, turning it into a less attractive option for unskilled riders who look at a low-displacement motorcycle just for occasional urban commutting. Its carburettor-fed 97,1cc single-cylinder air-cooled engine is not a speed-demon with its 6hp/7N.m, altough it still goes above the minimum 60 km/h minimum speed limit for motorcycles to be legally allowed for highway traffic in Brazil, and the average fuel consumption goes around 40 km/l (roughly 100 U.S. MPG).
Its dash has only the speedometer with an odometer and the check-lights for the turn signals, high-beam and neutral gear. There's not even a fuel level indicator, which became mainstream even among the Chinese entry-level motorcycles. Honda's strategy with the Pop 100 has been to offer a lower-cost option to counter-attack Chinese manufacturers who usually offer rip-offs of Honda designs such as the Super Cub and the CG 125, which in spite of offering many features not available in the original ones, including front-wheel disc brake with mechanical ABS in some models, still don't have as many dealers nationwide as Honda does.

Similar motorcycles from Chinese manufacturers cost no more than US$900 in Uruguay, while in Brazil due to higher taxes they would cost the equivalent to some US$1200, but Honda charges close to US$2000, which doesn't make it so popular, being quite overpriced due to its poor equipment level.

In spite of its unattractive features, there is still some market for the Pop 100, mostly due to the brand-loyalty developed around Honda in Brazil until mid '90s, when its local monopoly for 4-stroke motorcycles below 250cc began to decline.

FedEx minivan in Brazil

Fiat Doblò Cargo (1st generation, facelifted) from the Brazilian branch of FedEx, spotted in Porto Alegre a few days ago. This little beauty is fitted with a 1.4L SOHC 8-valve flexfuel engine (a 1.8L 16-valve is available as option) and a 5-speed manual transmission, rated to a 620kg (1367lbs) payload. This model is still made in Brazil, while the 2nd generation is made only in Turkey and more successful in export markets.

Volkswagen military truck in Brazil

Volkswagen Truck & Bus, currently a division of the MAN Group, had its roots in South America, mostly Brazil, when Volkswagenwerk AG acquired the local assets of Chrysler in late 70s, and altough the passenger cars were quickly phased out, the Dodge truck platform still served as a base for Volkswagen branded trucks, all fitted with a forward-control cabin co-developed with MAN for the usage in its G90 truck series, and were also used in some U.S.-spec Peterbilt and Kenworth Mid-Ranger trucks which had their production outsourced to VW Truck & Bus in its earliest production site. In the early 90s due to an agreement with Ford, the trucks started to share the platform with the Ford Cargo and to be built at a former Ford factory at the Ipiranga neighborhood in São Paulo, until 1997 when the partnership ended, and Volkswagen developed its first all-new truck platform, known as "modular" and still in use. The truck shown in these pictures is a Volkswagen 8-140 (about 8-ton GVWR and roundly 140hp) set to be used as a K-9 unit by Santa Catarina State Military Police, powered by an MWM 4.10TCA engine with a 4.3L displacement, developing a power of 138hp at 2600RPM and a 430Nm torque from 1600RPM thru 2000RPM, backed by a 5-speed manual transmission. It was also available in Europe thru '94 to 2000, with the same engine, but it had a lower differential ratio borrowed from the naturally-aspirated (8-100) version available in the Brazilian market. MWM is currently merged with International Engines, and also outsources the local assembly of the MAN engines used in the current lineup of Volkswagen and MAN trucks, and also the 2.8L Duramax engine used by Chevrolet for its midsize pickup and SUV range.

More mini hearses in Brazil

The low availability of new station-wagons, which were the stereotypical hearse for decades, is one of the factors leading to an increasement on the presence of those mini hearses in Brazil, but the ease to upfit a compact coupé-utility for the job is also to be taken into account. The vehicle featured is an early Chevrolet Montana, based in the platform of the Opel Corsa C and the Opel Combo, and was also available in South Africa as Opel Corsa Utility but didn't reach the European market. The open deck was extended and enclosed with a single-piece fiberglass canopy, totally integrated with the vehicle's original design, altough the taillights were replaced for the ones used in the Fiat Siena Fire, which was available in limited European markets as the Fiat Albea. The front grille seems to have been taken from the 1st-gen Kia Sorento, and there is a hood ornament resembling Jaguar's "leaping cat".

Even the Fiat Strada, available in European markets, is also occasionally upfitted with fiberglass hearse conversion kits.

Old Brazilian half-tonners repowered with Diesel engines

This Brazilian '64 Ford F-100 had the Y-Block 292cu.in. V8 replaced by a Brazilian-made MWM D-229-4 naturally-aspirated Diesel engine, a 4-cylinder close in size to the Cummins B-series. The 3-speed collumn-shifted manual transmission was also replaced by a floor-shifted 4-speed.

Dodge D-100, which had been also made in Brazil from '69 to '76, available only with the 318cu.in. V8 and a 3 on-the-tree manual transmission. One of the most popular engine for repowerings for this model in the Brazilian market was the Perkins 4-236, and a few ones had been even factory-fitted with this engine and a floor-shifted 4-speed manual transmission.

Both trucks were spotted at Largo da Epatur, in Porto Alegre, Brazil.
