Jaguar Mark 2

The Mark 2 came with a , or Jaguar XK engine. The 3.8 is similar to the unit used in the 3.8 E-Type (called XKE in the USA), having the same block, crank, connecting rods and pistons but different inlet manifold and carburation (two SUs versus three on the E-Type in Europe) and therefore less. The head of the six-cylinder engine in the Mark 2 had curved ports compared to the straight ports of the E-Type configuration. The 3.4 Litre and 3.8 Litre cars were fitted with twin SU HD6 carburettors and the 2.4 Litre with twin Solex carburettors. Aware of the importance of the quotable numbers to the US market Jaguar continued to use claimed gross bhp figures throughout the production period of the Mk II and 240/340 models. A direct conversion into DIN bhp is not possible, but the 3.8 Mk II engine developed about 190 bhp by modern DIN standards. This compares with the later 4.2 XJ6 engine which also gave around 190 bhp DIN, or 245 gross bhp according to Jaguar. The explanation was that the XJ6 4.2 engine was delivering the power at lower rpm. The camshaft timing and inlet and exhaust valve sizes were the same for the 2.4,3.4,3.8 Mk II and XJ6 4.2 engines, so the engines throttled themselves sooner in the bigger engine sizes. Later 4.2 XJ6 engines had special induction pipes, to reduce exhaust emissions, that crossed over between the inlet and exhaust sides of the engine. These reduced bhp to around 170 bhp on later production. ==Body==

The new car was re-engineered above the waistline, with vision dramatically improved by an 18% increase in cabin glass area. Slender front pillars allowed a wider windscreen, and the rear window almost wrapped around to the enlarged side windows, now with the familiar Jaguar D-shape above the back door and fully chromed frames for all the side windows. The radiator grille was changed, and larger side, tail and fog lamps were repositioned. Inside a new heating system was fitted and ducted to the rear compartment. There was an improved instrument layout that became standard for all Jaguar cars until the XJ series II of 1973. ==Mechanical changes==

The front suspension geometry was rearranged to raise the roll centre and the rear track widened. Four-wheel disc brakes were now standard. Power steering, overdrive or automatic transmissions could be fitted at extra cost. The 3.8 litre was supplied fitted with a limited-slip differential. The Mark 2 was over 100 kg heavier than the 2.4 / 3.4 cars. The car continued to use a live axle at the rear. ==240 and 340==

Some time on or about September 1967 the 3.8 litre model was discontinued and the 2.4 and 3.4 litre Mark 2 cars were rebadged as the 240 and 340 respectively as gap-fillers until the XJ6 arrived in September 1968. The 340 was discontinued at that time, but remaining Series 2 parts were used up producing budget-priced 240s until April 1969. These sold at £1364, only £20 more than the first 2.4 in 1956. resulting in a slight sales resurgence. The 240 and 340 models retained cost-saving downgrades that had appeared a year earlier in the Mark 2 series. Standard leather upholstery was replaced by Ambla, a leather-like synthetic material, and tufted carpet was used on the floor. The front fog lamps were replaced with circular vents and made optional for the UK market. The sales price was reduced to compete with the Rover 2000 TC. ==Production==

A 3.4 litre with automatic transmission tested by The Motor magazine in 1961 had a top speed of and could accelerate from 0- in 11.9 seconds. A touring fuel consumption of was recorded. The test car cost £1951 including taxes of £614. A 3.8 litre with the 220 bhp engine was capable of accelerating from 0- in 8.5 seconds and could reach a top speed of . ==Motorsport==

Jaguar also marketed from 1962 to 1969 a distinctive Daimler version of the Mark 2 branded Daimler 2.5 V8 fitted with Daimler's 2½-litre V8. In late 1967 it was re-labelled V8-250 when the Mark 2 became the Jaguar 240. As well as being significantly more powerful than the inline 6-cylinder 2.4-litre XK, the more modern Daimler engine was shorter and also lighter by about . This significant reduction in mass over the front wheels and redistribution of weight to the rear reduced understeer during hard cornering. These cars were externally identified by Daimler fluting at the top of the radiator grille and the top of the rear number plate lamp cover, their smoothness, and the sound of their V8 engine. They were given distinctive interior fittings. ==Legacy==

, inspired by the design of the Jaguar MK2|alt= The Mark 2's body lines, derived from the Mark 1, and overall layout proved sufficiently popular over time to provide inspiration for the second-generation Jaguar S-Type, a nostalgia model introduced in 1999. Brendan McAleer of the Globe and Mail described the 2015 Jaguar XE as the Mark 2's spiritual descendant. Japanese automaker Mitsuoka Motors produced the Viewt in 1994, a subcompact hatchback with Jaguar MK2 features. ==Portrayal in media==

The Mark 2 gained a reputation as a capable car among criminals and law enforcement alike; the 3.8 litre model being particularly fast with its 220 bhp (164 kW) engine driving the car from 0- in 8.5 seconds and to a top speed of with enough room for five adults. ==Notes==
