Waymo bids its self-driving bubble cars farewell

Say goodbye to Waymo's quirky bubble-shaped autonomous cars. Google's former self-driving car division is retiring its fleet of "Fireflies" - also known as "koalas" and "gumdrops," among many other nicknames - to focus on integrating its technology into more traditional vehicles. It particularly aims to give more people access to its self-driving technology through a fleet of 600 Chrysler Pacifica minivans, which the team has equipped with its latest custom-built radar, lidar and vision systems. The minivans also come with Waymo's newest AI platform that can see farther and more clearly. Plus, they run like normal vehicles do, unlike the Fireflies, which are limited to 25mph. This move doesn't exactly come as a surprise. A report from late 2016 said Alphabet's Larry Page scrapped Waymo's plans to manufacture bubble-shaped driverless vehicles to make the company's strategy more feasible. It said Page's new plan involves collaborating with automakers to design and make cars with no pedals and steering wheels that use Google's self-driving tech. Shortly after that report came out, Waymo introduced its heavily modified Chrysler Pacificas with altered electrical, powertrain, chassis and structural system to accommodate the extra weight of the company's equipment. While Waymo will no longer use its Fireflies for future tests, you can still catch a glimpse of the cute bubble cars in various locations. This August, they'll be on display at the Arizona Science Center in Phoenix before making their way to the The Thinkery in Austin, Texas, this October. You'll also find a Firefly at the Computer History Museum in Mountain View, California and another at the Design Museum in London.Written by Mariella Moon for Engadget. Waymo Related Video:

Junkyard Gem: 1982 Chrysler LeBaron Convertible

Things looked very grim at Chrysler during the late 1970s, as Oil Crisis-shocked car shoppers avoided buying thirsty land yachts and ancient-technology compacts in droves. The Carter administration grudgingly bailed out the company with loan guarantees in 1979 (leaving "small enough to fail" American Motors to seek help from the French government) and Chrysler needed a huge sales hit in a big hurry. Under the leadership of Lee Iacocca (freshly canned by Henry Ford II), Chrysler developed the modern, front-wheel-drive K Cars and the company was saved. The very first K Cars hit the road for the 1981 model year, and I'm always on the lookout for those historic early Ks when I'm searching for interesting bits of automotive history in junkyards. The '81 and '82s have become nearly impossible to find, but this once-plush LeBaron convertible appeared in a Northern California yard last month. While a bafflingly complex family tree of K-derived vehicles grew up in Chrysler showrooms through 1995 (including the hot-selling Caravan/Voyager/Town and Country minivans), the only "true" US-market K-Cars are the Dodge Aries, Dodge 400/600 coupe, Plymouth Reliant and Chrysler LeBaron. 1982 was the first model year for the K LeBaron and this car was built in March of that year, so we're looking at one of the very early successors to the Dodge Diplomat-based LeBarons of the 1970s. Chrysler developed a homegrown 2.2-liter, overhead-cam straight-four engine that proved very successful, and a 94-horsepower version of that engine was the base powerplant for the 1982 LeBaron. This car appears to have just about every option available that year, so of course the original buyer went for the 2.6-liter Mitsubishi Astron straight-four. With hemispherical combustion chambers, the 2.6 could be called a Hemi (a few Ks even got "2.6 HEMI" badging); horsepower came to just 93 in 1982, but the 132 pound-feet of torque beat out the 117 lb-ft of the Chrysler 2.2 that year. Silver-faced gauges and complicated radio controls were all the rage during the Late Malaise Era, and this car has both. Note the Chronometer next to the HVAC controls, a digital design with green vacuum-fluorescent display lifted from the previous-generation rear-wheel-drive LeBaron. The non-cloth bits of the convertible-top mechanism look decent enough, so perhaps some junkyard-shopping LeBaron owner will rescue them.

500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.
