Scania R420 – high-output 4-series with R-cab: 12-litre inline-six rated around 309 kW, multi-axle chassis for combination haulage, gross weights up to 47,200 kg
The Scania R420 also comes from the 4-series programme launched in 1995 with the R-cab for long-haul work; the number 420 denotes engine output in horsepower under Scania's convention, rather than the engine family as in the smaller series. The R420 is powered by Scania's twelve-litre inline six, which at this output level produces around 309 kW. The axle formulas in the model names – 6X2, 6X4, 8X4 – indicate three- and four-axle chassis with varying numbers of driven axles, typical of heavy haulage and timber transport in Scandinavia.

The register lists 9 versions with around 309 kW from six-cylinder engines of 11,700 to 12,742 cc. Kerb weights range from 7,960 to 22,570 kg, gross vehicle weights from 18,600 to 47,200 kg; the latter figure corresponds to multi-axle chassis for trailer or semi-trailer combinations. Lengths run from 6,155 to 11,650 mm, widths from 2,500 to 2,600 mm.
At 309 kW, the R420 was among the more powerful variants of the 4-series and was aimed at heavy long-haul and construction transport, and, in multi-axle form, at Scandinavian combination haulage with trailers exceeding the standard 40-tonne limit. Competitors included the Volvo FH12/FH16 and the heavier versions from MAN and Mercedes-Benz.
On used examples, it is worth checking the frame and trailer coupling for cracks, particularly on multi-axle construction and timber-transport chassis with high drawbar loads. The twelve-litre engine calls for checks of the turbocharger, charge-air cooler and injection system; the brakes should be inspected especially carefully given the high gross weights. Parts are well supported through Scania's service network, and the robust 4-series platform is also routinely serviced by independent workshops.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
