2012 Jaguar XF goes on a 816-mile trip using a single tank of diesel

Article by Christian Andrei, on June 28, 2011

The new Jaguar XF, powered by a 2.2-litre four-cylinder engine, is expected to be the most efficient vehicle that the company has ever been produced. In fact, a unit has recently completed an 816-mile trip from Castle Bromwich in Birmingham (the location of the factory where it was built) to Munich on one tank of diesel.

The standard XF was driven by David Madgwick, an independent tester, with Alexander Madgwick as his navigator. The XF was driven through a total of four countries, passing through urban traffic, twisting country roads, and motorways.

The XF had slightly more than 3,000-miles on the clock when it departed. It showed that it had consumed only 64-litres of fuel to average a very impressive 57 mpg.

Andy Whyman, Chief Programme Engineer for the XF, had met the car when it arrived in Munich. He said that the development team is “very proud” of the new XF 2.2 as this proves its efficiency as well as emphasizes the combination of high performance and economy. The XF also scores high in performance.

It delivers 190 PS and 332 lbs ft of torque, to enable the XF to sprint from zero to 62mph in only 8.5-seconds before getting to a top speed of 140mph. The XF 2.2 has a CO2 emissions rating level of 149 g/km.

This model is also the first Jaguar to feature a new 2.2-litre engine that’s attached to a new eight-speed ZF automatic gearbox and an innovative Stop-Start system. The new XF 2.2 is set to be launched this September and will form part of the new 2012 model range. The latest generation XF has a new appearance, and its interiors and equipment also received upgrades.

The 2012 Jaguar XF has won several awards and is highly regarded by car enthusiasts all over the world. And that is for several good reasons, top of which is its dramatic aesthetics and great performance.

For this line, the front end has been improved. The sheet metal changes to the grille, front wings and bonnet allow for the inclusion of triangular side vents that give the car a more manly, aggressive and sleeker look. These changes are more pronounced for the XFR models, where you have a more assertive design. On the other end of the spectrum, you can opt to have a more aerodynamic look for all other models under the 2012 Jaguar XF line. That brings three different styling options for you to choose from!

The new Xenon headlights allow for a sleeker design without compromising the beam resolution. You also have LED running lights that are arranged in the signature J-Blade pattern that has marked Jaguar cars over the years. The taillights are also LED and its look has been reworked: the tail lamps now extend to the center of the boot lid.

The new design comes in three new colors plus you can choose from an assortment of alloy wheels ranging from 17 inches to 20 inches. Ian Callum, Jaguar Cars' design director, explains that the XF deserves to be recognized as the quintessential Jaguar car, describing it as "purposeful yet elegant". Callum also relates that for the XF, the company made it a point to improve performance while also coming up with an astonishingly beautiful car.

Power train and dynamics

Jaguar XF has a 2.2 L AJ-i4D turbo diesel engine, giving you 190 PS of power. It also packs a lot of torque: 450 Newton meters. You can go from 0 to 60 mph in just eight seconds and reach top speeds of 140 miles per hour.

The engine has low friction pistons and a turbocharger that is water-cooled, thereby improving efficiency. It also features active engine mounts, while the sump and block have been modified to cut down on NVH levels. This is by far the most fuel-efficient engine for the British luxury car brand. However, it still delivers the performance that you have come to expect out of a Jaguar sports car. Added acoustic shielding, as well as computational fluid dynamics, guarantees smoother airflow on the exterior.

For a car of its strength, the Jaguar XF is also very eco-friendly, emitting only 149 grams per kilometer of carbon dioxide, effectively complying with Euro Stage V standards.

Eight-speed automatic

The Jaguar XF debuts an eight-speed ZF automatic gearbox. The eight-speeder has several benefits, including better economy and acceleration. You can change gears in as little as 200 milliseconds and it lends the car the ability to do multiple downshifts. And the best thing is that it is as light as the earlier six-speed transmission! Additional perks include the reduction of 169 grams per kilometer and better fuel economy.

Intelligent Stop/Start

The diesel engine is not the only new innovation that you would find in the 2012 Jaguar XF. One can also get to know Jaguar's Intelligent Stop/Start system. This is the first premium diesel car to have the technology. What does it do? It automatically shuts the engine down in around 300 milliseconds as soon as the car comes to a stop. That translates to a 5% to 7% reduction in carbon dioxide emissions and it provides better fuel economy. And the best thing is that the engine management software is doing all the work for the driver, no need to do anything! The management software takes into consideration several complex factors to help it determine when the engine should be stopped.

When you take your foot off the brakes, a Tandem Solenoid Starter will instantly rev the engine back to life, with enough time for it to run optimally before you would need to get on the accelerator.

The New Jaguar XF 2.2 Diesel: Four Countries, 1,313 Km, One Tank Of Fuel

Driven by David Madgwick, an independent tester, accompanied by navigator Alexander Madgwick, the scrupulously standard XF passed through four countries taking in a mix of winding country roads, motorways and dense urban traffic. The XF, with just over 5,000 km on the clock at the point of departure, consumed just 64-litres of fuel to average a remarkable 4.9 l/100km.
On-hand to meet the car on its arrival inMunichwas Andy Whyman, Chief Programme Engineer for the XF, who commented: 'The entire development team is very proud of what the new XF 2.2 has achieved - this not only proves the efficiency of the new model but underlines that performance and economy can be combined.'

Despite its keen focus on economy the XF 2.2 produces 190 PS and 332 lbs/ft of torque, to allow the XF to accelerate from rest to 100 km/h in just 8.5-seconds before reaching a top speed of 225 km/h. The XF 2.2 emits just 149 g/km of CO2. Further improving efficiency, the new 2.2-litre engine is linked to a new eight-speed ZF automatic gearbox and an innovative Stop-Start system - marking the first time such a device has been fitted to a Jaguar.

Set to be launched in September, the new XF 2.2 forms part of the new 2012 model range. Benefitting from a fresh new look, upgraded interiors and equipment as well as improvements in efficiency and refinement, the latest generation XF looks set to build on the achievements of the model it replaces.
