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.

Jaguar to create Panthera electric vehicle platform in-house

Jaguar Land Rover CEO Thierry Bollore isn't trying to make Jaguar's turnaround, called "Reimagine," easy nor inexpensive. What it appears he's most interested in doing is making sure the turnaround creates a range of Jaguar electric vehicles that exude the historic Jaguar-ness the brand still gets credit for but hasn't been known for in a while. He had told Autocar last year that future products must be "really modern luxury cars that are the copy of nothing in style or design, the top of technology and refinement, but not looking backwards." Since then, the brand had cast around for an existing electric platform created by another automaker or a supplier that it could adopt for Jaguar use, but nothing met the standard. Instead, Autocar now reports the English carmaker will create its own EV platform in-house. Company CFO Adrian Mardell said in an investor call the platform is called "Panthera," which is the scientific name for the genus of large cats that include jaguars, leopards, lions, and tigers. Bollore said, "Concerning the new Jaguar, we're making unique proportion a priority. That's the reason why at the moment we do it by ourselves." Some have fastened on the phrase "at the moment" to suggest the Panthera plan could be temporary. And while that's possible — there have been a lot of temporary plans all over the industry for the past few years — Jaguar is expected to release the first EV in its new lineup in 2025, so the plan couldn't be temporary for long. Slightly under four years from now would be just enough time to create a new mechanical architecture on a new technical foundation to serve a new vehicle. Emphasis on "just." The Panthera platform makes sense, if Jaguar can pull it off. Bollore wants the coming Jaguars to be considered alongside Bentley and Aston Martin, so he'll need those unique proportions along with brilliant design to draw buyers that haven't considered the brand in ages, if ever. The makeup of the revamped model line remains murky. On the sedan side, it's thought the XE and XF might become a single midsize four-door. The return of a true flagship sedan isn't clear, but it seems a good possibility considering the intended competition and as a differentiator with sister brand Land Rover. As to crossovers, the E-Pace and F-Pace might make the transition to battery power, and a new J-Pace flagship crossover looking unlikely in order to, again, maintain space from Land Rover.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
