FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Hands on with the concepts of the Moab Easter Jeep Safari

Jeep has a way of tugging at the heartstrings of its enthusiastic owner base when the annual Moab Easter Jeep Safari rolls around. The 2015 version sees all boxes ticked in the off-road event's 49th year: multiple diesel engines on display, a pickup-truck-like model and more than a few nods to the brand's long and storied history book. We were able to get a first-hand look at the seven concepts being shown in Utah's Red Desert in the much cooler, cleaner confines of the FCA Technical Center's Design Dome. Jeep Chief Concept We aren't sure if it's that throwback chrome grille or the eye-catching Ocean Blue paint, but even more than the Red Rock Responder, the Chief drew our eye as soon as we walked into the Design Dome. It's a surprisingly tall vehicle, but it's also very wide. We'd also wager it's longer than your typical four-door Wrangler. Jeep may have used a Wrangler as a base for the Chief, but any similarities to the donor vehicle are extremely difficult to spot. The fenders and doors are probably the biggest giveaways, but you're going to need to squint (and have the benefit of a Wrangler to compare with, like we did) to pick out Wrangler bits. As is the recurring theme throughout all seven concepts, the Jeep design team's attention to detail is borderline fanatical. From the "Surf Rated" badge on the fenders, to the tweaked door handles to the bumper stickers in the cargo area and the Tiki-statue-shaped shifter, the little details are truly the stars of the Chief Concept. The rosewood trim in the rear cargo area is stunning and adds to the Beach-Boy-friendly stylings of the Chief. The throwback grille, round headlights and tall, skinny taillights, meanwhile, add a lot of personality to the exterior. The high beltline and lower roof gives the Chief a chop-topped look, but it's arguably the least successful element to the blue concept's otherwise impressive design. All of the vehicles Jeep put together for Moab are 100-percent functional. That's not surprising with some of the vehicles you'll see below, but it somehow is remarkably impressive given the degree of the changes Jeep made in putting together the Chief. Jeep Wrangler Red Rock Responder The Wrangler-based Red Rock Responder is arguably one of the most capable of these real-world vehicles, both in terms of the way it looks and its actual hardware. We mentioned the special rescue equipment fitted to the bright-red, truck-like Jeep – a compressor and air gun, sockets, tow straps, etc.

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).
