Competition is not bad. It is how one handles competition that makes all the difference. If understood correctly, competition can be a great part of one's life as it can motivate to do something better than had been done before, or, increase one's own level of performance to a whole different standard.

In the late 1950s, Jaguar faced tremendous competition from BMW and Mercedes-Benz. BMW had introduced its 507 Roadster with a 3.2 liter V-8 engine and Mercedes-Benz unveiled its 300SL in 1955 with a 3.0 liter six-cylinder engine. These were favorites in its day, as they still are even now. This was tremendous and fierce competition to have to face off against. The question for Britain's sports car production company was, 'How would they respond?' Would the company see the challenge as an opportunity, or, would it bow to the German auto makers? Jaguar did not bow and, in fact, responded with a true classic of its own.

The car company already had been producing its familiar and well-loved XK-series, but, in 1957, it introduced what was, perhaps, its best evolution of the chassis, the XK150.

The XK150 bore a striking resemblance to its 120 and 140 predecessors, but its similarities ended with the aesthetics. In almost all respects the car was a revolutionary step-up from the 120 and 140.

The engine bonnet was widened, as was the grille. The two-piece windscreen that had been seen on the 120 and 140 had been replaced with a single curved windscreen. The profile lines of the car didn't drop and fall away toward the rear of the car as had been designed in the 140. Instead, the XK150 had a higher profile around the doors.

Underneath the engine bonnet lie another of the improvements. The XK150 had been given a 3.4 liter dual overhead cam straight-six engine. While the 150 was slower than its predecessors initially, that aspect too would be changed. Both the 120 and 140 had been utilizing C-Type cylinder heads. Jaguar introduced another 150 variant in 1958 called the 'S' and this used a Harry Weslake-modified straight-port 'S' head. This increased the horsepower of the XK150S from 190 bhp to 250 bhp. To help control this increase in power, Jaguar had introduced on the XK150 race-bred, four-wheel disc brakes. For the first time ever on a series production car disc brakes were offered for all four wheels. Three SU carburetors were employed on the 150 S, whereas the 150 just had dual carburetors. This helped control fuel-flow much more efficiently. To deliver the power to the wheels, Jaguar employed a four-speed manual transmission, which had overdrive.

The interior of the XK150 was also revised. The 120 and 140 models had wood trimmed dashboards, specifically walnut. Up until 1958, the center dash had an aluminum panel with X-pattern engraving. All of this was dropped. Instead, Jaguar went with leather trimmed dashboards.

Jaguar was done boosting their 150. And, in 1960, Jaguar dropped their 3.4 liter engine in favor of a 265 bhp 3.8 liter engine. This allowed the car to be able to reach speeds in excess of 130 mph. The Motor magazine road tested the car and, at that time, it was the fastest closed-cabin car they had tested.

Only 89 examples of the XK150 S were built out of the 2,862 XK150s built through 1961. An XK150 S example in the United States was even more-rare, and, that is what rolled across the auction block at the RM Auction in Arizona.

Complete with its 265 bhp, 3.8 liter inline six-cylinder engine, chassis number T838705DN represented Jaguar's ultimate XK-series car. Originally purchased in Ontario in 1960, this Jaguar Drophead Coupe's interior was trimmed in red leather and featured a black finish. The car underwent a complete 'body-off' restoration back in 2003. The gearbox and the engine have gone through an entire rebuild and the paintwork has been redone to concours quality.

This example of the XK150 S comes with other little surprises as well. One of those added bonuses included a matching set of Connolly leather luggage and a set of chrome wire wheels. Presented at the auction in 2011 was Jaguar's ultimate version of the XK-series and surely caused fond memories of Britain's counterattack in the sports car market. Surely, Jaguar faced its challenges and delivered a classic winner.

The drophead coupe and fixed head coupe body styles were introduced in 1957 and was followed the following year with a roadster. The XK150 was the last of Jaguar's XK-series and Jaguar celebrated this legacy with numerous upgrades and changes that Jaguar's engineers had learned from designing both the Xk120 and XK140. The curvaceous and dramatic lines of the XK120 and XK140 were smoothed out giving it a more elegant and conservative design. In the front, the bonnet was widened and lengthened, and the front grill was enlarged to allow the engine to breathe better. The interior featured a leather-trimmed dashboard and thinner doors, giving the inside more room and more luxurious ambiance. Four-wheel disc brakes improved stopping power and was a first for a production car. The engine was fitted with a dual overhead cam straight-six with either 3.4 or 3.8 liters of displacement.

This Fixed Head Coupe was originally fitted with the 3.8-liter engine and finished in Imperial Maroon with a black leather interior. The current owner acquired the car in 1985, at which time it was fitted with a 3.4-liter engine. A two year frame-off restoration was undertaken in 1990. Since that time, it has lived a pampered life, accumulating less than 200 miles. Currently, the odometer shows a total of 78,000 miles.

This Jaguar XK150 was completed on February 15th of 1960 and then shipped to Jaguar of Eastern Canada. The car was equipped with the 3.8-liter engine and fitted with the so-called B-Type cylinder head, as found on the 3.4-liter Special Equipment model. The Standard and SE 3.4-liter models produced 190- and 210-hosrepower while this particular example produced 220 horsepower. It is one of only two thousand six hundred seventy-two drophead coupe models produced, which represent just twenty-eight percent of total XK150 production.

From new, this car has been treated to a high-quality restoration, with virtually no expense spared. The body was refinished in British Racing Green and given a black convertible top. The interior is trimmed in green leather.

The car has a four-speed gearbox with Laycock de Normanville overdrive, dual fog lamps, five chrome wire wheels with period-style Dunlop Roadspeed RS5 tires, a proper dual-exhaust system, and a fully equipment trunk compartment with a jack and tools.

In 1957 Jaguar introduced the XK150, a replacement for the XK140. The XK140 had been a replacement for the XK120 which had started the XK series with its elegant styling and impressive 120 mph capabilities. At the time, the XK120 was the fastest production vehicle in the world. The XK150 had many similarities to its predecessors but it featured modern styling and improved mechanics.
When the XK150 was introduced, it could be purchased in DropHead Coupe or FixedHead Coupe configuration. The Open Two Seater (OTS) Roadster version appeared a year later.

The base engine was a DOHC 3.4 liter straight-six that produced 180 horsepower. Most of the vehicles were outfitted with the SE version which had a modified cylinder head, dual SU HD6 carburetors, and larger exhaust valves bringing the horsepower rating to 210. Performance was further increased in 1958 when Jaguar enlarged the bore bringing the liter capacity to 3.8 and the horsepower rating to 220. The 'S' model featured three SU HD8 carburetors and a modified cylinder head bringing the horsepower rating to 260.

The XK120 suffered from poor steering. This was resolved by the adaptation of a rack-and-pinion unit on the XK140. The XK150 used the similar rack-and-pinion configuration, though still lacking power-assistance. The chassis was also similar to its predecessor. Disc brakes were standard on all four corners of the vehicle. The wheels could be ordered as Wire or as discs wheels.

Improvements continued in the interior of the vehicle. With roll-up door windows and door handles, the XK150 was more civilized. The longer hood meant the XK150 Roadsters were just a two seater unlike its 2+2 predecessors.

During its production lifespan lasting from 1958 through 1961, the Fixed Head Coupes were the most popular with 4445 examples being created. That figure was followed by the Drop Head Coupes with around 2670 examples. There were around 2260 Roadsters produced. The Roadster production figures would have been higher if they had not been introduced ten months after the Fixed and Drophead Coupe versions.

The XK150 continued the elegance and performance established by the XK120 and reinforced by the XK140. The long flowing lines of the hood gracefully curved towards the vertical grille which hid a potent engine that made the car legendary.
