There were only 12,055 XK 120 made between 1948-1954 and starting at chassis number 670001. This one is chassis number 670220 clearly stamped on the frame and written XK120M670220 in my owners manual. This is a steel frame, steel body, aluminum hood, doors and trunk production car. My owners manual shows the Engine number being W 6101-8 S but the engine block in this car is marked W 1463-8. The body number is stamped F1288. I completely rebuilt the engine and head June 2013, rebuilt steering box and installed a modern rear main seal. I upgraded the transmission with a modern 5 speed kit designed specially for the xk120. Other upgrades include flame thrower distributor, solid core plug wires, electric fan, steering mantel with signal light switch, stainless steel sport exhaust and Dynalite alternator which looks like the original dyno generator. I'm just finishing the dash in this car so, please note the headlight switch knob and bezel is ordered. I will try to add more pictures and video. Here is a little history lesson from Wikipedia. The XK120 was launched in open two-seater or (US) roadster form at the 1948 London Motor Show as a testbed and show car for the new Jaguar XK engine. The display car was the first prototype, chassis number 670001. It looked almost identical to the production cars except that the straight outer pillars of its windscreen would be curved on the production version. The roadster caused a sensation, which persuaded Jaguar founder and design boss William Lyons to put it into production. Beginning in 1948, the first 242 cars wore wood-framed open 2-seater bodies with aluminium panels.[4] Production switched to the 1cwt or 112 lb (51 kg) heavier[5] all-steel in early 1950. The "120" in the name referred to the aluminium car's 120 mph (193 km/h) top speed (faster with the windscreen removed), which made it the world's fastest production car at the time of its launch.[6] In 1949 the first production roadster, chassis number 670003, was delivered to Clark Gable. The XK120 was ultimately available in two open versions, first as an open 2-seater described in the US market as the roadster (and designated OTS, for open two-seater, in America), then also as a drophead coupe (DHC) from 1953; and also as a closed, or fixed head coupe (FHC) from 1951. A smaller-engined version 2-litres, 4 cylinders, intended for the UK market was cancelled prior to production. On May 30, 1949, on the empty Ostend-Jabbeke motorway in Belgium, a prototype XK120 timed by the officials of the Royal Automobile Club of Belgium achieved an average of runs in opposing directions of 132.6 mph with the windscreen replaced by just one small aeroscreen and a catalogued alternative top gear ratio,[note 1] and 135 mph with a passenger-side tonneau cover in place.[7] In 1950 and 1951, at a banked oval track in France, XK120 roadsters averaged over 100 mph for 24 hours and over 130 mph for an hour, and in 1952 a fixed-head coupe took numerous world records for speed and distance when it averaged 100 mph for a week. Roadsters were also successful in racing and rallying. The first roadsters, hand-built with aluminium bodies on ash frames mounted on modified Jaguar Mark V chassis, were constructed between late 1948 and early 1950. To meet demand, and beginning with the 1950 model year, all subsequent XK120s were mass-produced with pressed-steel bodies. They retained aluminium doors, bonnet, and boot lid. The DHC and FHC versions, more luxuriously appointed than the roadsters, had wind-up windows and also wood veneers on the dashboard and interior door caps. With alloy cylinder head and twin side-draft SU carburetors, the dual overhead-cam 3.4 L straight-6 XK engine was comparatively advanced for a mass-produced unit of the time. With standard 8:1 compression ratio it developed 160 bhp (119 kW),[2] using 80 octane fuel. Most of the early cars were exported; a 7:1 low-compression version, with consequently reduced performance, was reserved for the UK market, where the post-war austerity measures then in force restricted buyers to 70 octane "Pool petrol". The Jaguar factory, with access to 80 octane fuel, provided roadsters with the higher compression ratio to the press. Journalists could then test the model's optimum performance in Belgium, on a long, straight stretch of road between Jabbeke andOstend.[8] The XK engine's basic design, later modified into 3.8 and 4.2 litre versions, survived into the late 1980s. All XK120s had independent torsion bar front suspension, semi-elliptic leaf springs at the rear, recirculating ball steering, telescopically adjustable steering column, and all-round 12 inch drum brakes[3] that were prone to fade. Some cars were fitted with Alfin (ALuminium FINned) brake drums to help overcome the fade. |

This classic Jaguar XJ has a 720-hp ungentlemanly secret
Tue, 19 Nov 2013Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.
Jaguar tests autonomous vehicle technology with 100-car fleet
Wed, Jul 13 2016Jaguar Land Rover is exploring how to take autonomous vehicle technology off the paved path. But the company has plans for technology on tarmac, too. The company announced that the Jaguar division will have a fleet of 100 cars testing autonomous technologies on public roads. The testing process will cover a period of four years and begin with vehicle-to-vehicle and vehicle-to-infrastructure communication systems, along with a stereo camera system and autonomous vehicle software. These systems will work together to provide a variety of features that could make their way into future Jaguars and Land Rovers. The first feature in development is called "Roadwork Assist." The system relies on the stereo camera to create a 3D image the car's software can analyze. The software can identify road cones and other barriers associated with construction sites. The car will then alert the driver about entering the construction zone and provide some steering assistance to keep the car centered in its lane. Tony Harper, Jaguar's head of research, said that this system can reduce stress on the driver, and the technology could eventually be used to allow the car to pilot itself through construction zones. Another of Jaguar's proposed features is "Safe Pullaway," which also relies on cameras and software. The Safe Pullaway feature is designed to prevent close-proximity collisions in traffic jams and even in the garage. To do this, the car watches the area immediately ahead of it for obstacles. If the car detects something nearby while the driver adds throttle or shifts into gear, it will apply the brakes to prevent driving into the object. The final project on Jaguar's plate is its "Over the Horizon Warning" system. This will be one of the first features to rely on Jaguar's vehicle-to-vehicle communication technology. The idea is that connected cars in constant communication will give drivers additional warning of upcoming hazards, such as out-of-sight animals and slowed or stopped cars. In Jaguar's example of a stopped car, the stationary vehicle would send a signal alerting approaching cars of the situation. In turn, the approaching vehicles would trigger audible and visual warnings to drivers about the hidden car. Jaguar says that the system could also be applied to emergency vehicles. Emergency vehicles would broadcast a signal to alert drivers well before the lights and sirens get their attention. This would give emergency vehicles a faster, safer path through traffic.
Tata to get Jaguar and Land Rover tech, platforms too?
Tue, 22 Jul 2014Since buying Jaguar Land Rover, Indian automaker Tata has generally left its luxury arm's platforms and technology alone. However, those days might be gone. The two of them are gradually growing closer with coordinated development and rumors of shared platforms. And it looks like all of that work and money is finally going to pay off with an actual vehicle in the near future.
According to Australian website Drive, Tata wants to make its cars more attractive to buyers outside of India, and to do that the company knows it must improve quality. The Indian company is being careful, though, because it doesn't want to dilute the Jaguar or Land Rover brands with cheap models. "You're going to see in the future a lot of sharing of technologies and platforms over time, but you won't see a JLR with a Tata badge on it," said Darren Bowler, managing director of Tata's Australian distributor, to Drive.
According to Bowler, these future vehicles are already on the way. Tata and JLR have a global platform in the works for 2017 that both companies could use for cars or crossovers. He also hinted that Jaguar's new Ingenium engines could be shared among the brands in the future, too.
