Hino forced to rethink specification
From the 1st of December 2016, all commercial vehicles with a GVM of 3 501kg or more must have a pre-selected speed limiter fitted.
Hino‘s interpretation of a ‘pre-selected speed limiter’ is a tamper-free speed limiter. This means that its customers and its dealers should not be able to change the settings of the limiter; the only way to change it should be through programming of the ECU at the production level.
Heavy and extra-heavy commercial vehicles and buses (including minibuses), will be limited to 80km/h from December 2016. On the 1st of January 2017, all commercial vehicles by the same definition must also have ABS fitted – excluding 4×4 models – which must have their ABS fitted by May 2017.
It is important to note that this requirement is production-based. In other words, all vehicles produced from 1 January 2017 must comply, but anything built before then can still be sold next year without the ABS spec.
The Toyota Dyna will change market category in 2017, moving from a medium commercial vehicle to a light commercial vehicle. This change is not driven by the market, but rather by the physical capabilities of the vehicle.
The Dyna uses a 5’L’ Toyota engine designed in the early 70s – without an ECU.
Hino South Africa looked at a locally developed, mechanical speed limiter for this engine in order for it to meet local regulations, but says there is no tamper-free device in existence currently.
Its choice was to either stop sales of the Dyna completely in South Africa or change its category. According to Hino, it’s relatively easy to change Dyna’s category as it sits right at the edge of the GVM cut-off between a light commercial vehicle and a medium commercial vehicle. In fact, removing 50kg from Dyna’s tare weight places it right at the limit of LCV designation (3 500kg).
By removing 50kg, the Dyna doesn’t need a speed limiter or code 10 driver.
Hino customers can now put a driver behind the wheel that has a normal passenger car license. There is also a cost implication for customers as they no longer need to do an annual COF. There is no change from an application point of view as payload remains unchanged.
There will be extra scope, especially through the Toyota dealer network for selling the Dyna as a bakkie, although it is still a chassis cab. Simultaneously, Hino will introduce a new cab for the Dyna, common with the narrow cab on the 300 series. Dyna will still be badged a Toyota, with ABS added to comply with the new regulations.
The 300 series will, from September, be equipped with the 100km/h tamper-free speed limiter in Hino’s production facilities. The air intact on the back of the cab will also be raised, following feedback from customers, becoming a stacked air intake on single-cab models.
500 series models will, by the end of August 2016, be equipped with Euro 3 engines in order to accommodate the speed limiter, with the Euro 2 engine unable to be programmed to accept the restriction. The Euro 3 engine uses common rail diesel injection but has the same base as the outgoing Euro 2 (JO8C) engine.
The introduction of the Euro 3 engine will increase output to 180 horsepower from 170 horsepower, making the 1017 a 1018 – that is, a vehicle with a 10-tonne GVM and 180 horsepower. The company’s 1324 model will become 1326 which, until now, used a hydraulic braking system. This will change to a full air system, with ABS.
In November 2016, speed limiting will be introduced in the 500 series, which will be staggered with the 300 series, since the settings happen at Hino Motors Limited (HML).
It’s important to note that the 2026, which is part of the 500 series range, is equipped with a Euro 4 engine. So none of the above-mentioned changes applies to it.
HML had to develop a new engine for the 4×4 1322 to accommodate speed limiting. As a result, the local introduction of this vehicle has been delayed until May 2017.
The 4×4 model will receive the Euro 3 engine and an 80km/h speed limiter. The company will also introduce a single-wheel application model, as it currently only offers a dual-wheel application.
In January 2017, the 700 series will receive speed limiting. Hino is bringing back the Euro 2 engine to satisfy those customers that are struggling to obtain 50ppm diesel. Again, this has a cost implication for its customers, as 500ppm diesel is always priced lower than 50ppm diesel.
A Euro 2 engine will further assist cross-border operators where 50ppm is hard to come by. Hino is not discontinuing the Euro 4 engine – it will still be available – but only on customer order.
