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).

Jeep in St. Louis hacked from Pittsburgh

One of America's most popular vehicles contains a security flaw that allows hackers to remotely commandeer it from anywhere on the planet. Cyber-security researchers Chris Valasek and Charlie Miller say they've accessed critical vehicle controls on a 2014 Jeep Cherokee that allowed them to remotely control critical vehicle functions like braking, transmission function, and steering. Automakers have downplayed the possibility a car could be remotely compromised, but the significance of the findings detailed Tuesday could cause them to reevaluate the threats posed to hundreds of thousands of vehicles already on the road. A key finding – the pair needed no physical access to the Jeep to pull off the attack. Valasek and Miller accessed the controls via a security hole in the Sprint cellular connection to Chrysler's UConnect infotainment system. In the course of their research, Valasek sat in his Pittsburgh home and remotely manipulated Miller's Jeep as he drove along a highway outside St. Louis. If you know a car's IP address, they say, a hacker could control it from anywhere. "We didn't add anything, didn't touch it," Valasek told Autoblog. "A customer could drive one of these things off a lot, and they'd have no clue it had these open attack surfaces." Remotely, he disabled brakes, turned the radio volume up, engaged windshield wipers and tampered with the transmission. Further, they could conduct surveillance on the Jeep, measuring its speed and tracking its whereabouts. They conducted the experiments over multiple breaches. They made their findings public on the same day the National Highway Traffic Safety Administration, the federal agency in charge of vehicle safety, released its latest report on the readiness of government and automakers to fend off these sorts of cyber attacks. Later today, two US Senators are expected to introduce legislation that would help consumers better understand the potential risks of car hacking. In the early stages of their research, Valasek and Miller found a security flaw in the car's wi-fi that allowed them to remotely manipulate controls from a range of about three feet. But in recent months, they found another vulnerability in the Sprint cellular connection in the UConnect system. That was a key breakthrough. "Lo and behold, we found we could communicate with this thing using cellular, and then more research, and 'Holy cow,' we're using the Sprint network to communicate with these vehicles," Valasek said.

2015 Jeep Renegade Sport 4x4 Quick Spin [w/video]

Which is the most entertaining Jeep Renegade you can get? While one might make an argument for the Trailhawk model and its accompanying off-road hardware and consequential go-anywhere ability, that car comes with one glaring flaw – its 2.4-liter engine and nine-speed automatic transmission just aren't very entertaining. Instead, I submit the turbocharged, 1.4-liter base engine and its accompanying six-speed manual, a position that was reinforced after a recent stint behind the wheel of a very basic Sport 4x4. Not only do you get a fair amount of the Trailhawk's off-road ability – the Selec-Terrain system and a 4WD Lock mode are standard, but you'll be without the 20:1 crawl ratio and Rock off-road mode – you'll also enjoy a more dynamically interesting powertrain. Read on to see why the force-induced Renegade might just be the way to go. Driving Notes My first date with the Renegade was on the mostly empty, winding roads of northern California. There, the 1.4-liter turbocharged inline-four with 160 horsepower and 184 pound-feet of torque felt fine – with no traffic and few stoplights along the drive route, it was easy to keep the engine on boil. But this engine isn't as enjoyable in day-to-day suburban traffic. Power arrives suddenly – peak torque comes between 2,500 and 4,000 rpm – and if you don't use it, you lose it. There's not much oomph in the higher end of the rev range. With such a peaky powerband, it's easy to get caught flat-footed if you're not paying attention. Thankfully the manual transmission makes it simple to stay engaged and in the correct gear. The stick-shift is enjoyable to use, with a firm clutch that's easy to modulate and shift action that isn't sloppy or vague. The 1.4-liter engine sounds good. Turn down the stereo, stomp on the throttle, and you'll be treated to a delicious turbo whistle and a smooth exhaust note. I've said it before and I'll say it again: I want Mopar to offer the Fiat 500 Abarth's exhaust on the Renegade. It'd be fun. If you do prefer the stereo, know that the Renegade's standard four-speaker unit is weak. Base models don't offer Bluetooth or satellite radio, but you can add both of those luxuries, two extra speakers, and a five-inch touchscreen for just $695. Not a bad bargain. The Koni frequency selective dampers do an excellent job of managing both small, frequent imperfections (like freeway expansion joints), and the bigger potholes that still haven't been fixed after the havoc of Detroit's winter.
