heralded a new streamlined look, the single-driver cab and more power. CM talks to operators who rely on it daily, asking: is it a good long-term purchase?
y 1996, Scania's 3-Series had run its course in the UK and was replaced by the 4-Series. The new tractor range came with a bigger cab that offered more comfort inside and smoother lines on the outside.
Sonic_ diehards thought it too pretty, preferring the harder lines of the previous model, but it was quickly accepted by most operators who could see the benefits of more aerodynamic styling that incorporated a tapered front end with a near vertical front screen, rounded corners with integral corner deflectors and optional enclosed steps.
The new interior of the R Topline sleeper offered the driver more living space than had ever been available in a Scania before. It was taller, wider and longer than earlier models and the space was utilised to advantage by placing the 88cm (2ft loin) wide top bunk above the front screen which, when not in use, can be tilted up to further increase head room.
Shallow aircraft-style lockers mounted on the back wall look stylish, but are not the most practical. On the standard R cab, the layout for bunks and lockers is more conventional.
In all R cabs, the steering wheel can be adjusted through a 20' arc with a Gomm variable reach in front of the driver's luxury seat, which includes heating, lumbar support and a squab that tilts and slides. The two-part backrest can be angled as a single unit, while air suspension can be as soft or as firm as required.
The front of the cab opens to give access g for daily checks. All noise-shielding is built rl
into the cab, and it does not have to be :4 detached to give access to the engine. There E2 was the odd idea that didn't quite work out first time, like the low folding step, but, overri all, the cab has lines that could enhance the image of any fleet.
One key fits the doors and the ignition, g which are designed to deter even the most g persistent thief.
In 1998, the more comfortable single-driver cab concept was introduced. Substantially 2 redesigned V8 14.o-litre and straight-six 11.0litre engines were joined by a new six-cylinder DSiz 11.7-litre unit with EDC. From the start, the 4-Series was specified in the R124 to meet Euro-2 legislation, and was offered at both 36ohp and 400hp.
The advent of Euro-3 saw the 24-valve 400 replaced by the 420, equipped with HPI electronic injection.
Although announced in April 1999, it wasn't available in RHD until the middle of zoo'. In terms of both volume and timing, H PI is the most accurate injection control ever fitted to a Scania. Scania's automated transmission, Opticruise, was offered as an option on all Euro-3 engines. With the introduction of 44 tonnes, Scania's 124 moved on again with the addition of turbo compounding, so squeezing even more power out of the 11.7-litre engine, now rated as high as 47ohp.
