Hairpin valve springs are used, as on the racing engines. The chassis huts a wheelbase of 7 ft. 10 in. and weighs under 13 cwt. With a touring all-enveloping two-seater body the weight is still below 16 cwt. and everything about the car, appearance, facia layout, central remote control of the four-speed gearbox, is sas the enthusiast would wish it. The prototype was in Nark, with green leather upholstery. The speed is claimed as 149 m.p.h. Look out., Allard. .Jaguar and DB II ? * * *

During a lecture before the Institution of Production Engineers by Mr. john Silver, Production Manager of Jaguar Cars, some interesting points emerged. The production of Jaguar engines is approximately 250 a month. Each engine is run-in for four hours on the bench on coal gas, a gas.earburetter feeding through. the twin -S.U.s. A further three-hour run is then given at 2000-2,500 r.p.m.. stepped up for another hour at 2,500 r.pati. and a final hour on petrol at 3,000 r.p.m. During this latter run a flash full-bore b,h.p. reading is taken, a tolerance of -1or — 5 b.h.p. being observed. A short road test completes matters. The Mk. V Jaguar has 1/. good !word in respect of
cylinder wear, these ears tic )1 ),( 111 70,000 0-121es before requiring a rebore. Mr. Silver, oiling the NE120, rat her laughed off the 2,800 ft. per iMit. pist 00speed maximum ; he said that Ian Appleyard’s XE120 was not a speciallyprepared car. * * *
