Jaguar XJ13, 1966

Jaguar XJ13, 1966

 The Jaguar XJ13 was a prototype racing car developed by Jaguar to challenge at Le Mans in the mid-1960s. It never raced, and only one was ever produced.

Jaguar had considered the manufacture of a V12 engine as far back as 1955, initially for racing purposes, and then developing a road going version, unlike the XK which was designed as a production engine and later pressed into service for racing. The engine design was essentially two XK 6-cylinder engines on a common crankshaft with an aluminium cylinder block, although there were differences in the inlet porting, valve angles and combustion chamber shape. The first engine ran in July of 1964.

The idea of a mid-engined prototype was first mooted in 1960, but it was not until 1965 that construction began, with the first car running by March 1966. The aluminium body was designed by Malcolm Sayer, the aerodynamicist responsible for the Jaguar C-Type, D-Type, E-Type and XJ-S, who used his Bristol Aeroplane Company background to build it using techniques borrowed from the aircraft industry.

The Jaguar XJ13 had mid-engine format with the 5.0 litre V12 engine mounted behind the driver, used as a stressed chassis member together with the five-speed manual ZF Transaxle driving the rear wheels.

The front suspension wishbones were similar to that of the E-Type, however where the E-Type used longitudinal torsion bars, the Jaguar XJ13 had more conventional coil spring/damper units. At the rear there again remained similarities with the E-Type - the use of driveshafts as upper transverse links - however the rest was quite different, with two long radius arms per side angling back from the central body tub together with lower links.

The development of the Jaguar XJ13, although treated seriously by the designers, was never a priority for company management (despite assistant MD Lofty England's Le Mans success in the 1950s), and became less so following the 1966 merger with BMC. By that time Ford had developed the 7.0 litre GT40, and so the Jaguar XJ13 was considered obsolete by the time the prototype was complete. The prototype was tested at MIRA and at Silverstone, which confirmed that it would have required considerable development to make it competitive. The prototype was put into storage and no further examples were made.

Jaguar Mark 2, 1959

Jaguar Mark 2, 1959

The Jaguar Mark 2 is a medium sized saloon car built from 1959 to 1967 by the Jaguar company in Coventry, England, as successors to the Jaguar 2.4 and 3.4 models, manufactured between 1957 and 1959. These retrospectively became known as the Jaguar Mark 1 following the release of the Mark 2 in 1959.

Adhering to Sir William Lyons' maxim of "grace, pace and space", the Mark 2 was a beautiful, fast and capable saloon. It came with a 120 bhp 2.4 L, 210 bhp 3.4 L or 220 bhp 3.8 L Jaguar XK6 engine. The 3.8 is similar to the unit used in the 3.8 E-Type (XKE), having the same block, crank, connecting rods and pistons but different inlet manifold and carburetion (two SUs versus three on the E-Type in Europe) and therefore 30 bhp 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. For markets other than the US the 3.4 was fitted with twin SU carburettors and the 2.4 with twin Solexes, but three Solexes were used in US spec 3.4s and 3.8s in order to meet SMOG emissions legislation. This reduced power output over the equivalent SU carburetted examples.

The Daimler 2.5 litre engine was fitted to the Daimler 250 derivative of the Mark 2 (In European markets known as the Daimler 2.5-V8 then Daimler V8-250), having first been used in the Daimler SP250 sports car (the SP250 was originally known as the Daimler Dart but "Dart" was a trademark of Dodge and had to be dropped by Daimler under threat of legal action.) The aluminium alloy Daimler engine was lighter than the cast iron block Jaguar sixes, therefore reducing the mass over the front wheels and hence reducing understeer compared to the XK-powered versions under hard cornering. These models were recognisable by the characteristic Daimler wavy fluting incorporated in the chrome grille instead of the Jaguar badge and figurine.

The Mark 2 was discontinued in September 1967 and replaced by the 240 and 340, so named to distinguish them from the old 2.4 and 3.4 which, as noted above, became known as the Mark 1 following the introduction of the Mark 2 in 1959. The Jaguar 240 and 340 were interim models to fill the gap until the introduction of the XJ6 in September 1968. The 340 was discontinued immediately but the 240 continued as a budget priced model until April 1969; its price of £1364 was only £20 more than the first 2.4 in 1956. (Eric Dymock, The Jaguar File, 3rd edition, 2004, Dove Publishing.)

The economies of the new 240 and 340 models came at a cost - the leather upholstery was replaced by 'Ambla' leather-like material and slimmer, more economical front and rear bumpers were introduced. Other changes included the replacement of the front fog lamps with circular vents and optional fog lamps for the UK market. The sales price was reduced to compete with the Rover 2000 TC.

The 240's performance was improved over the old 2.4 model by upgrading the 2.4's cylinder head and twin Solex carburettors to the straight port 'E-Type' head and twin SU carburettors. For the first time the 2.4 litre model could exceed 100 mph resulting in a slight sales resurgence.

Performance
A 3.4 litre car with automatic transmission tested by The Motor magazine in 1961 had a top speed of 119.9 mph (193.0 km/h) and could accelerate from 0-60 mph (97 km/h) in 11.9 seconds. A touring fuel consumption of 19.0 miles per imperial gallon (14.9 L/100 km; 15.8 mpg-US) was recorded. The test car cost £1951 including taxes of £614.

A 3.8 litre car with the 220 bhp engine was capable of accelerating from 0-60 mph (97 km/h) in 8.5 seconds and could reach a top speed of 125 mph (201 km/h).

Jaguar XK SS, 1957

Jaguar XK SS, 1957

 

After Jaguar withdrew from racing the company offered the remaining, unfinished chassis as the roadgoing Jaguar XK SS, by making changes to the racers: adding an extra seat, another door, a full-width windshield and folding top, as concessions to practicality. However, on the evening of 12 February 1957, a fire broke out at the Browns Lane plant destroying nine of the twenty-five cars that had already been completed or were semi-completed. Production is thought to have included 53 customer D-types, 18 factory team cars, and 16 XK SS versions.

Following Jaguar's withdrawal from competition at the end of the 1955 season, a number of completed and partially complete D-types remained unsold at the Browns Lane factory. In an attempt to recoup some of the investment made in building these unused chassis, and to exploit the lucrative American market for high-performance European sports cars, Sir William Lyons decided to convert a number to full road-going specification. Only minor changes were made to the basic D-type structure: the addition of a passenger side door, the removal of the large fin behind the driver's seat, and the removal of the divider between passenger and driver seats. 

 

In addition, changes were made for cosmetic, comfort and legal reasons: a full-width, chrome-surrounded windscreen was added; sidescreens were added to both driver and passenger doors; a rudimentary, folding, fabric roof was added for weather protection; chromed bumpers were added front and rear (a styling cue later used on the E-type); XK140 rear light clusters mounted higher on the wings; and thin chrome strips added to the edge of the front light fairings. In total 16 Jaguar XK SS were made, with most being sold in the USA, before the Browns Lane fire destroyed the remaining chassis.

 

Infiniti M45, 2003

Infiniti M45, 2003

2003
The 2003 M45 was based on the Y34-series Nissan Gloria/Nissan Cedric, with styling similar to the Gloria. The engine is Nissan's 340 hp VK45DE V8 which produces 333 ft.lbf of torque. The rather Japanese squared-off styling did not make much of a splash on the US market, and the M45 sold poorly.

2006
Infiniti released a completely redesigned M for the 2006 model year to compete directly in the mid-size sport luxury class, against such class stalwarts as the BMW 5-Series and the Mercedes-Benz E-Class. It uses a much more rigid version of the G35/350Z/FX Nissan FM platform and is available with the common VQ-series 280 hp (208 kW) 3.5 L V6 in the M35, or the Q45's 335 hp (249 kW) 4.5 L V8 in the M45.

The automotive press has awarded the M several best-in-class awards in direct comparisons against its competitors. Despite entering a very crowded, competitive segment in which almost every member has been recently redesigned, the M still managed to find many key distinctions: Both the M35 and M45 are fastest in their class (0-60 in 6.3 and 5.4 seconds, respectively). The M is near or at the top of every interior dimension, actually breaking into the EPA "large" category depending on which option packages are selected. In fact, while being smaller on the outside than the flagship Q45, the M45 boasts more room, greater performance, a superior multilink front suspension, and much friendlier ergonomics, threatening the position of the flagship Q45.

All-wheel-drive models are called the M35x, which uses a sports car derived system (ATTESA-ETS) to send all power to the rear wheels until slip is detected.

The M line was released in February 2005 (at almost exactly the same time as the new 2006 Lexus GS) and its first several months of sales have been far beyond expectations. Prices in the US (USD) range from approximately 40,000 - 55,000, which feature for feature tend towards the lowest in class

Infiniti I35, 2009

Infiniti I35, 2009

 

The I30 and I35 were front wheel drive luxury cars from Nissan's Infiniti marque. Both were rebadged Nissan Maxima sedans.

The I30 was redesigned for 2000 along with the Maxima. Engine power was up to 227 hp but the manual transmission was no longer offered.

In late 2001 the model got its most significant host of upgrades, including minor revisions to the interior, new optional equipment, larger brakes, a re-tuned suspension system, and standard stability control. The car was renamed I35 to reflect an engine-displacement increase from 3.0 to 3.5 L. Nissan's VQ35DE V6 produced 255 hp. Styling was also updated.

Infiniti wanted to convince buyers that the new suspension tuning, enlarged brakes, stability control and 255 horsepower engine had transformed the I into more of a sports sedan and less of sedate entry-level model, but was largely unsuccessful. The model was only available with a 4-speed automatic transmission and front wheel drive, meaning that the ES300 and the base version Acura's then-new TL remained its closest competitors, and models like the 5-Series remained out of its league, as was Acura's Type-S version of the TL.

In September 2004, Nissan announced that I35 production would cease and that model year 2004 would be the last for this vehicle. Infiniti discontinued the I after a short run of 2004 models. The I was succeeded by the new Infiniti G35 (introduced for 2003).
