Jaguara Mark V wyposażono praktycznie w te same silniki 2,7 i 3,5 litra. O ile wersja 2,5-litrowa odznaczała się tym samym rozstawem osi co modele przedwojenne, to 3,5-litrówka otrzymała zmodyfikowane nadwozie o rozstawie osi 330 cm z dość mocno pochyloną przednią szybą, podwójnymi zderzakami, reflektorami wkomponowanymi w błotniki i zakrytymi tylnymi kołami.


Jaguar 1½-, 2½- and 3½-Litre Saloon models are continue from 1947 and in October were joined by revised 2½- and 3½-Litre Mark V models. Mid-1948 prices were: 1½-Litre £953 (special equipment model £1009), 2½-Litre £1189, 3½ -Litre £1263.

SALIENT FEATURES OF THE Jaguar TYPE XK ENGINES
 
In this new ranfe of Jaguar engines all compromise in design has been eliminate. Each engine can be truthfully stated to incoroprate all the most advanced technical knolwledge available to-day on naturally aspired petrol engines. Tests carried out on the completed units have shown the wisdom of the decision taken by the Jaguar Company nearly nine years ago to develop an engine on these lines.
In addition to bench tests, totalling many thousands of hours, wxtensive road tests at home and abroad have been carried out and it is significant that 2 litre engine, loaned to Colonel Gardner when he broke the world speed reCord in the 2 litre class at 176 miles per hour, is a completely standard unit with the exception of modified pistons to give a higher compression ratio.
From the following condensed resume of the more important features of the Type XK engine, it will be seen that no reliance has been placed upon the use of new or untried inventions. Instead, a blend of known and proved detail designs of the highest efficiency has resulted in the creation of a production engine of unparalleled quality and performance.
The following are some of the more important points: (1) Hemispherical head of high strength aluminium alloy, (2) Valve seatings of special high expansion cast iron alloy are shrunk into the combustion head, (3) Induction system, including the valve parts, were designed in collaboration with Mr. Harry Weslake, (4) Twin overhead camshafts, driven by a two-stage chain, (5) Oiling system - exceptionally large capacity oil pump, (6) Exhaust valves of high grade austenetic steel immune from lead attack, (7) Water circulation - direct flow across the head from a high pressure pump, (8) The crankshaft is a 65 ton steel forging, adequately counterweighted. The main bearing are larger than have ever beem previously used on passenger car engines and are responsible for the exceptional smoothness with which these engines deliver their power, which is maintained up to the high maximum r.p.m. of which these engines are capable. The four cylinder has three bearings and the six cylinder has seven bearings. The bearings themselves are of the Vandervell thin shell type and have shown on the test to have practically unlimited life, (9) Pistons - are Aerolithe aluminium alloy, fitted with chromium plated top rings, which tests show give over 100 per cent increase in life to the bores.
