Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

Sunday Drive: Trucks and SUVs of all shapes and sizes

The American automotive marketplace is dominated by trucks and SUVs, and so was the last week of coverage on Autoblog. By far, the most popular story of the week was our First Drive of the 2018 Lincoln Navigator. It may look like an old-school lumberer, but in reality Lincoln's flagship is a thoroughly modern, turbocharged-V6-powered, three-row, luxury people mover. The Jeep Wrangler is the world's most recognizable vehicle. So it's no surprise that the next version looks a whole heck of a lot like the last one, and the one before. It's all in the details, which is why we were so excited when Jeep decided to unleash a trio of images showing both two- and four-door Wranglers for us to dissect ahead of the SUV's official debut at the L.A. Auto Show later this year. Past that, spy photos of the next Chevy Silverado and Ram 1500 were predictably popular. See both of those below, and the cap it all off, check out the entire week's worth of SEMA coverage – including the bonkers Hennessey VelociRaptor 6x6 – in our mega image gallery at the bottom of this post. Enjoy! As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Lincoln Navigator First Drive | From black sheep to flagship 2018 Jeep Wrangler revealed: First photos released before L.A.

Junkyard Gem: 1983 Jeep DJ-5L Mail Dispatcher

When it comes to putting mail in boxes, a simple and reliable vehicle works best. Say, a zero-frills steel box on wheels, with right-hand-drive, a fuel-efficient four-cylinder engine, no-hassle automatic transmission, sliding doors, and a big mail-sorting table instead of a passenger seat. That's what the AM General Mail Dispatcher DJ-5 was all about, and these bouncy little trucks were everywhere for decades. Here's a late-production example, still in USPS colors, spotted in a Denver-area self-service wrecking yard. Neither snow nor rain nor heat nor gloom of night stayed this courier from the swift completion of its appointed rounds. Note the "Sonic Eagle" USPS logos on the doors; this became the official USPS logo in 1993, nearly a decade after the final Jeep DJ-5s were built. Plenty of these trucks stayed in service into our current century, and a few are still being used by private mail-delivery contractors in rural areas. During the American Motors era of Jeep DJ production (1970 through 1984), a bewildering assortment of engines went into postal Jeeps. This is a 2.5-liter GM Iron Duke four-cylinder; before that, DJ-5s came with Audi power (more or less the same engine used in the Porsche 924, in fact), AMC straight-sixes, and Chevy Nova four-cylinders. The 1984 DJ-5Ms ran the AMC 2.5-liter four-cylinder. The earliest DJs were equipped with three-speed manual transmissions, but the American Motors-built postal-delivery versions all had automatic transmissions. This one has a three-speed Chrysler Torqueflite A904, a weird engine/transmission combination that should help you stump your friends during car-trivia debates. Check out the ultra-bare-bones heater/ventilation controls! These trucks were badged as AM Generals, not Jeeps (I couldn't find a single Jeep label anywhere on this one), just like the original HMMWV. However, you'd have to be a real hair-splitter to refer to this as an AM General DJ-5 instead of just Mail Jeep or Jeep DJ-5. Next time you complain about your subcompact rental car lacking driver-comfort features, consider this vehicle. I had a few high-school friends who owned DJ-5s, back in the early 1980s when they were available for a couple hundred bucks at government-surplus auctions. The first thing civilian DJ-5 owners always did was tear out the mail-sorting table and replace it with a random junkyard bucket seat (or an aluminum lawn chair). These trucks were very noisy, very bouncy, and very slow, but they always ran.
