2018 Woodward Dream Cruise: What to know and where to go

If there's anything that proves Detroit's motor-oil-in-the-veins, gearhead bonafides, it's the annual Woodward Dream Cruise, which will bring an anticipated 1.5 million or so people from near and far, plus tens of thousands of classic and custom and just plain weird cars, to a 16-mile portion of Woodward Avenue on Saturday for the 24th year. Loved by gearheads, collectors and the merely curious, who see it as the Motor City's version of Mardi Gras, and loathed by others, who deride it as the world's largest traffic jam, the Dream Cruise is nothing if not an explosion for the senses. What will you see there? Well, as Autoblog Managing Editor Greg Rasa put it last year, "There are historic cars. And works of art. Some are worth vast sums of money, and some are rat rods and rust buckets. And some are bizarre creations that make you ask, 'What were they thinking?'" A few things are certain: You will see many incredible automobiles. There will be plenty of T-shirts and other merch, official and not-so-much. It will be crowded, and probably hot. The Cruise will officially go from 9 a.m. to 9 p.m., though of course cruisers have been out already for weeks. And there are plenty of attractions, both on and off the pavement of Woodward. Tony Michaels, the Dream Cruise's executive director, said the event is special for the Detroit region. "Together we celebrate the automobile and what it has meant to us," he told Autoblog. "To see the these fantastic vehicles and the proud owners says so much about who we are and our pride. "People should take it in to see history running 16 miles down Woodward Avenue and to be a part of the greatest automobile event in America." Ford is once again serving as the Dream Cruise presenting sponsor and will hold the 20th anniversary of the Mustang Alley at the corner of Nine Mile and Woodward in Ferndale, where it expects as many as 1,000 Mustangs to line up. It will also show off its lineage of trucks at 13 Mile, along with several performance vehicles at Duggan's Irish Pub at 31501 Woodward in Royal Oak. The company on Thursday unveiled the 2018 Mustang Cobra Jet drag car to celebrate the nameplate's 50th anniversary. Just 68 examples are planned of the $130,000 limited-edition model Other Ford activities include: Sales of tickets for a raffle of a one-off Kona Blue Mustang Bullitt, starting at the media clubhouse at 2 p.m. Friday. The raffle itself takes place in November and will support juvenile diabetes research.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Corvette + fireworks = so much glory

You might think that those of us making our living by reviewing cars, think critically about the cars we're driving most of the time. It could be that I'm an underachiever, but that's not the case with me. In fact, unless I'm set to the review task, I typically think about the cars in front of and around me more frequently. That's because a) you never know what you're going to see out there, and b) all of them could be out to bump/scratch/tailgate/crash me out. You can never be too careful. Such was the case when I was driving a 2015 Chevy Corvette earlier this week. I'd already had my fun finding the edges of grip on a river road in the car, the night before; on the morning in question I was just trying to get to work. But while scanning the suburban streets for potential dangers to the 'Vette's neat-o Daytona Sunrise orange paint, I spied a XXL-sized fireworks tent in an empty parking lot. Oh right, I remembered, 4th of July weekend. That obvious bit of observation lead to a chain of thought along these lines: "We should do something with this car for the 4th" ... "Too bad I have to give it back tomorrow." ... "Wonder if I could do a quick video?" ... "Wonder if I can set off a bunch of fireworks in slow-mo for a video?" The result, well, I won't call it genius, but I will say that I remember why every kid loves fireworks. And I will call it glorious. Happy 4th, y'all.
