Jaguar’s UK sales of its facelifted XF are expected to get a 30% boost with the release of its new four-cylinder diesel. It has an entry price of just under £31,000. The new 2.2 i4D diesel will bring the XF to the mainstream of the executive saloon market, a segment that contributes as much as 90% of some rivals’ sales.
Jaguar boss Adrian Hallmark said that by matching the powertrain to the market segments, it will enhance sales. The revised XF that was seen at the recent New York motor show had received a significant facelift.
The visual components ahead of the A-pillar are new. Design chief Ian Callum said that this is “definitely the best facelift” that he has done at Jaguar. He said that these revisions make the XF seem “a bit more serious.”
Another model that could be on its way is a four-wheel-drive XF, which will intensify the penetration into the snowbelt states of the US, including New York. Approximately three-quarters of executive saloon sales in the snowbelt area are all-wheel drive.
Jaguar has recently acknowledged that it is preparing to launch a series of new models by 2016. This includes 40 new and revised models and powertrains.
Jaguar Land Rover chief executive Ralf Speth said that it is the “most ambitious new product program” ever in JLR. Speth said that for product innovation, the company is spending billions of pounds. Speth said that these plans have “just” been approved by the board of JLR owner Tata Motors.
The latest version of the new Jaguar XF could be specified with the new 2.2-liter AJ-i4D turbodiesel engine that provides up to 190PS of output and up to 450Nm of torque. This allows the Jaguar sports saloon to accelerate from nil to 60 mph in just 8.0 seconds and reach a top speed of 140mph. This new AJ-i4D turbodiesel is specified with low-friction pistons and a water-cooled turbocharger for greater efficiency.
It also features active engine mounts and modifications to the sump and block for better NVH numbers. All of these features make the 2.2-liter AJ-i4D turbodiesel as the carmaker’s most fuel-efficient engine to date, while still providing a level of performance expected of a Jaguar sports saloon as well as refinement comparable to 2.7-litre V6 diesel previously fitted on the XF. In addition, all models feature extra acoustic shielding and the use computational fluid dynamics for smoother exterior airflow.
As a result, the AJ-i4D turbodiesel engine – despite its power – could still achieve 52.3 miles on a gallon of diesel (EU combined cycle) while emitting just 149 grams of carbon dioxide per kilometer travelled.
Interestingly, this new diesel engine is already Euro Stage V compliant. Sending power from the engine to the wheels of the Jaguar XF is an all-new eight-speed ZF automatic transmission adapted specifically for application in a Jaguar. This transmission – engineered to deliver better acceleration and economy – could complete gear changes in just 200 milliseconds and could permit multiple downshifts through its paddleshift technology.
This eight-speed ZF automatic transmission practically weighs the same as the previous six-speed transmission, thanks to the use of lightweight materials. However, compared to its predecessor, the new eight-speed transmission is more efficient because of its enhanced pump design and gear control elements. In fact, this gearbox lowers the amount of carbon dioxide emitted by the 3.0-liter V6 engine to 169g/km and allows it to travel farther per gallon of fuel (44.8mpg).
The new 2.2-liter AJ-i4D turbodiesel engine also features Jaguar's new Intelligent Stop/Start technology that could automatically shut down the powerplant in 300 milliseconds after the XF comes to a halt, thereby helping improve fuel efficient and lower carbon dioxide emissions by between five percent and seven percent. This system features engine management software that could analyze several factors before deciding to stop the engine.
The engine will revive as soon as the brake pedal is depressed, thanks to a Tandem Solenoid Starter with a dedicated secondary battery. This process is further improved with the Hydraulic Impulse Storage feature of the transmission, supplying needed oil pressure for activating the shift elements. All Jaguar XF diesel models could be specified with the carmaker’s Adaptive Dynamics system that optimizes the saloon’s chassis control.
