Thomas AR 1941: heavy N3-class lorry with a six-cylinder engine, 10,837 cc displacement, four wheels, a gross vehicle weight of 19,000 kg and a kerb weight of 12,415 kg, built in 2008

The register holds no other series from the manufacturer Thomas, so this text describes the vehicle class the AR 1941 of 2008 represents: a two-axle chassis with a large six-cylinder engine for heavy bodywork.

The AR 1941 is driven by a six-cylinder engine of 10,837 cc displacement. At a length of 7,550 mm and a width of 2,550 mm, the vehicle rides on four wheels and a wheelbase of 4,000 mm; kerb weight is 12,415 kg.

At a gross vehicle weight of 19,000 kg the AR 1941 falls into EU class N3 above 12 t, for which a top speed of 90 km/h applies across the EU. Kerb weight and gross weight differ by 6,585 kg of payload margin. Four wheels at nearly 19 t gross vehicle weight mean high axle loads on only two axles, a configuration found chiefly on construction vehicles with a short wheelbase built for good manoeuvrability.

Buying such a two-axle heavy vehicle second-hand, the front and rear axles should be checked especially carefully for wear, since both axles carry the full weight load. The six-cylinder engine with its 10.8-litre displacement calls for a check of the turbocharger and cooling system, and given the 2008 build year, the exhaust after-treatment system is also worth checking, since these components are put under particular strain by intensive use on construction sites and by the short wheelbase's tight turning cycles.
