Jaguar's XF diesel isn't just fuel efficient, it's the cheapest XF available

Jaguar announced the 2017 Jaguar XF will now offer the 2.0-liter turbocharged diesel the company introduced on the XE. In addition to returning an impressive 42 miles per gallon on the highway and 31 in the city, the diesel is the cheapest XF available at $48,445. This means that picking the oil-burner will save you $3,040 over the cheapest gas V6 version, which only manages 29 mpg on the highway and 20 in the city. With 180 horsepower, the diesel is significantly down on power compared with the base V6 model. As a result, the diesel moves slower. Jaguar estimates the base V6 is good for a 5.2-second 0-60 time and the diesel should be able to do the same in 8 seconds. However, that's the only real downside. Even with the slower acceleration times, the diesel still has a very usable 317 lb-ft of torque available from 1,750-2,500 rpm. Based on our test drive of a diesel-equipped XE, the engine also breaks the old diesel stereotypes. It's both quite smooth and responsive. Unless you seriously need that straight-line performance, the Jaguar XF diesel arguably makes the most sense. It provides significant price savings and better fuel economy. The diesel XF also joins the XE and F-Pace diesels, leaving just the XJ and F-Type as the only Jaguars without compression-ignition engines. The British automaker is planning to remedy that, as a Jaguar Land Rover executive said the company plans to also add a diesel XJ variant in the US, even in the wake of the VW diesel scandal.

Junkyard Gem: 1977 Jaguar XJ6L

British Leyland began selling the Jaguar XJ in 1968, and production continued through multiple platform generations (and corporate owners) until just a few years ago. The original XJ was facelifted twice, in 1973 and 1979, with sales of the six-cylinder version extending into 1987 (Series 3 cars with V12s were built through 1992). Production numbers were never very high, but these cars proved popular in the United States and I still find them every so often during my junkyard travels. Here's a Series 2 XJ6 saloon that showed up in a Denver-area self-service yard last winter. Jaguar introduced a long-wheelbase version of the XJ saloon for 1972, giving it a four-inch stretch in order to better compete against the planned Rover P8. Since Rover was a fellow British Leyland brand, this was like Buick pouring big resources into crushing a threat from Oldsmobile, to the detriment of the overall company. In any case, the long-wheelbase saloons proved so successful that the short-wheelbase four-doors got the axe a couple of years later (the coupes stayed on the shorter chassis). Jaguar continued to add the "L" badging to the saloons for quite a while after that, presumably because it looked classy. The paint on all the upper body surfaces has been nuked down to the steel by the relentless High Plains sun, so we can assume that this car spent a decade or three sitting parked outside. It may have started out in Arizona, one of the few places with fiercer sunlight than eastern Colorado. Is it possible that it really turned a mere 46,630 miles during its life? With most cars of this vintage, I'd assume that the five-digit odometer has been turned over once or twice. With a Jaguar and its troublesome electrical components made by the Prince of Darkness, however, that's not such a sure bet. To own a car like this, you need to be willing and able to give it the money and work it requires to stay on the road; not many are suited to this responsibility. The interior looks to have been in very nice condition before the car got parked in a field somewhere. The wood interior trim has seen better days. Back in the 1970s, Mercedes-Benz had a big edge over Jaguar with mechanical sophistication and build quality, granted, but Jaguar beat those Stuttgarters hands-down when it came to making a car interior feel like a billionaire's library. The engine is a 4.2-liter XK6 straight-six, rated at 162 horsepower and 225 pound-feet.

Jaguar Land Rover reveals EV concepts, details green strategy

While it offers diesel models and even a couple hybrids, Jaguar Land Rover isn't quite as fleshed out on alternative powertrains as its luxurious German rivals. That should change pretty soon. JLR revealed three concepts at the CENEX Low Carbon Vehicle event in Millbrook, England, today. The Concept_e "research demonstrators" all use a new electric drive module, an EV system that the Indian-owned, British-based outfit claims will double the power and torque of today' electric motors. JLR says these modular EDMs can be paired with any of the company's engines or transmissions to create either a mild hybrid, a plug-in hybrid, or a pure EV. So yeah, this is kind of a big deal. Arguably the most exciting offering is a one-of-a-kind research vehicle. Riding on JLR's aluminium aluminum architecture, it ties together two electric motors – an 85-kW unit with a single-speed trans on the front axle and a 145-kW rear motor that's been mated to a two-speed transmission – with a 70-kWh li-ion battery that's mounted in the underbody of the car. There's also the Concept_e MHEV. This is a Range Rover Evoque that's been fitted with a mild hybrid system. Just a refresher, but a mild hybrid is very different than what's found in either a Chevrolet Volt or Toyota Prius, as it uses the electric motor and battery pack to simply assist the internal combustion engine, rather than for an electric driving mode. Reflecting that use, this particular Evoque uses a 15-kilowatt electric motor and a 48-volt, lithium-ion battery pack alongside a 90-metric-horsepower diesel-powered prototype. Finally, we have a Range Rover Sport-based plug-in hybrid. This brute uses a 300-metric-horsepower prototype gas engine and an eight-speed automatic alongside a 150-kilowatt electric motor. Energy is stored in a trunk-mounted, 320-volt, li-ion battery back. Partially funded by the British government, the EDMs are the result of a 16.3-million-pound ($25-million) research-and-development program. They're built in house by JLR, but were developed alongside 12 partners. While these concepts are exciting, don't get your hopes up to see a plug-in Jaguar XF or an all-electric Discovery Sport in your local dealer any time soon. "This is a long-term Jaguar Land Rover research project exploring all aspects of future hybrid and battery electric vehicle technology," JLR research and design boss Dr. Wolfgang Epple said in the attached statement.
