example, now preserved The first models of 1979 were based on the
Leyland National, but were powered by a
Saurer 240 bhp underfloor engine and
Allison fully-automatic transmission instead of the Leyland components. Other parts like the axles and the steering mechanism were also from Leyland. Four of these buses saw extended trials in the United Kingdom with the
South Yorkshire Passenger Transport Executive, (SYPTE) and were demonstrated with other UK operators, with seven purchased by
British Airways. ==DAB body type==
