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).

2020 Jaguar XE updated inside and out, diesel engine dropped

For the 2020 Jaguar XE sports sedan, less is more, at least in terms of powertrain offerings and trim levels. But the new, slimmer lineup adopts additional tech features, and the model also sees design tweaks inside and out. The diesel engine and the 3.0-liter V6 have been axed. The 247-horsepower 2.0-liter turbocharged Ingenium inline-four is the base engine. It's mated to an eight-speed automatic transmission and can be had with rear-wheel drive or all-wheel drive. This base engine's new model designation is P250, versus 25t previously. The step-up engine is the 296-hp version of the Ingenium 2.0-liter. Cars so equipped wear a new P300 badge, in place of the previous 30t. All-wheel drive is now standard with the 296-hp engine, and Jaguar claims a zero-to-60-mph time of 5.4 seconds for this powertrain. The exterior design tweaks include new bumpers front and rear, a reshaped rear valence, as well as new LED headlights and taillights. A wider grille with lattice mesh is supposed to draw the XE closer visually to the I-Pace EV. The previous thicket of trim levels — Premium, Prestige, R-Sport, S, Portfolio, and Landmark — have been pruned to just two: S and R-Dynamic S. Newly available is Jaguar Land Rover's InControl Touch Pro Duo infotainment system, which uses a second screen for climate control, flanked by two large knobs that can operate different functions (temperature, fan speed, and seat heating/cooling). The new rearview camera mirror eliminates blind spots, and wireless device charging has been added to the center console. Jaguar also has ditched the rotary shifter in favor of pistol-type shifter found in the F-Type and elsewhere, while surrounding it with a variety of controls, including a flipper switch to toggle among the car's different drive modes. A beefier steering wheel includes capacitive-touch switches. Newly designed seats, with standard leather, are claimed to be more comfortable, while redesigned door panels incorporate wider, softer armrests as well as increased storage capability. Base pricing climbs from $37,990 for the old rear-wheel-drive 20t to $40,895 (including destination) for the new P250. The AWD P250 is $42,894, while the P300 is $47,290. The 2020 Jaguar XE is on sale now. Related Video:

Automotive Grade Linux will be the backbone of your connected car

Creating a backend for a secure, reliable, and expandable infotainment system is costly and time consuming. The Linux Foundation, a non-profit organization, has set out to promote and advance the Linux operating system in commercial products. Automotive Grade Linux, or AGL, is a group within the Foundation that seeks to apply a Linux backend to a number of automotive applications in a variety of vehicles from various suppliers and manufacturers. AGL's goal is to create a common, unifying framework that allows developers and manufacturers to easily implement applications across platforms. Currently, the focus is on infotainment systems, but AGL has plans for instrument clusters, heads-up displays, and eventually active safety software. At CES, a display from Panasonic showed a completely digital and customizable dashboard that allows information and apps to be moved from the gauge cluster to the infotainment screen and back, all through the use of gesture and touch controls. Although the organization has been around for five years, it's really only been in the past three that the group has been working hand in hand with automakers and suppliers. The first two OEMs to participate, Toyota and Jaguar Land Rover, have since been joined by Mazda, Suzuki, Ford, and, as of this week, Daimler. The latter is important as until now most of AGL's partner's have been based in Japan or the US. Other partners include suppliers Denso, Renesas, Continental, Qualcomm, and Intel. AGL want's to supply roughly 80 percent of the backend, allowing partners to then finish and refine the Linux system for each individual application. Think of how the Android operating system is refined and customized for individual smartphones from Samsung, LG, and Motorola. While the final product looks different, developers can have an application that will work across all AGL systems. Because it is open source, anyone can use and develop for AGL. You can even go onto the group's website and download a copy right now. There is also a software development kit available that helps facilitate app creation on the platform. Vehicle development cycles take roughly five years, so there currently are no cars that run an AGL backbone available for consumers. AGL Executive Director Dan Cauchy says products should be hitting the market later this year, with even more coming in 2018. Right now, the industry is relatively fragmented when it comes to infotainment and related systems.
