WE USUALLY manage to include one odd-ball test in any year and this year was no exception. This particular -oddball-, the Stonefield, is poised to do very well in an undersupplied market — the allwheel-drive sector.
Stonefield, founded by the late Jim McKelvie, is a joint venture with the Scottish Development agency, as the vehicle is being built at Cumnock. Ayrshire. Two versions are available, a 4x4 and a 6x4. A choice of Ford V6 or Chrysler V8 engines are available and our test vehicle was fitted with the' former.
The Ford unit develops 102kW (138bhp) and drives all four wheels via a Ford C3 automatic gearbox and a transposing box which divides the effort, using an epicyclic differential, 37/63 per cent front to rear.
A space-frame chassis is used, made from square and rectangular tubular steel. Body panels are riveted to the sidemembers of the frame and are not load bearing. During test, which was naturally camri out on some of the rough+ terrain we could find, t Stonefield with 250kg (5c1 payload proved itself virtue unstoppable.
The approach angle at 1 front is 50deg and the r 45deg and this enabled 1 Stonefield to traverse 15ft h. test humps without difficul No performance or fuel ci sum ption tests were carried c but an estimated figure of 3! lit/100km (8mpg) seems likE At a basic price of C-210,50( fills the gap between exist British and imported all-whE drives.
