nuTonomy beats Uber to market with self-driving taxi rides, and the latest Corvette ZR1spy shots | Autoblog Minute

Software developer nuTonomy beats Uber to market with self-driving taxi rides in Singapore. A 124 Coupe could soon join Fiat's roadster lineup, and we have the latest spy shots of the new Corvette ZR!. Senior Editor Greg Migliore reports on this edition of Autoblog Mintue.

Show full video transcript text [00:00:00] Massachusetts based software company, nuTonomy, launched its self-driving taxi service in Singapore this week. nuTonomy specializes in developing software for self-driving cars. Testing of the companies ride-hailing smartphone app occurred in Singapore, where riders were able to book a free driverless ride. nuTonomy's robo-taxi fleet is comprised of Renault Zoes and Mitsubishi i-MiEVs. Engineers from nuTonomy were present at this public launch as a safety measure. [00:00:30] The company will now continue to collect data and conduct more testing with its self-driving cars in Singapore, Michigan and the United Kingdom. nuTonomy has plans to offer widely-available commercial service in Singapore in 2018. nuTonomy's aggressive play in Singapore has put Uber and its partner Volvo in the unlikely position of playing catch-up. Autocar reported this week that we should expect FCA to add a Coupe [00:01:00] to it's 124 roadster lineup. When? Well, seeing as the 124 Spider just recently made it US dealers we may have to wait until next year to see a hardtop Fiata. It's tough to predict what kind of performance we can expect out of a 124 Coupe but in the U.S. the Spider has 160hp using a 1.4-l turbocharged engine. So the car you see in these pictures is actually Fiat's 124 Rally car that will be used for competition. [00:01:30] Now that's not exactly how the street car will look but it gives you an idea of what a 124 with a fixed roof is gonna look like. This week we got another look at what we think is the Chevy Corvette ZR1 and its massive rear wing. Now to be clear, the images that we're seeing are actually demonstrations. The car was actually captured without the rear wing. However, our spy photographers photoshopped the wing, which we've seen before, on some of these new shots just so you could get [00:02:00] a sense of what the car looks like driving around in it's most recent state. Now we think this car will make more than 700hp, which is kind of a magic number. The Hellcats from Chrysler make 707 so certainly GM wants to beat them.

GM's redesigned full-size 2021 SUVs face delay over coronavirus

As General Motors works to conserve cash for the coronavirus pandemic, the automaker reportedly told suppliers that it is postponing development of several future vehicles. The situation may cause GM to delay the launch of the 2021 Cadillac Escalade, GMC Yukon, Chevrolet Tahoe and Chevrolet Suburban SUVs, which had been planned to roll out in April. The original launch plan for the redesigned full-size SUVs, which are some of the most profitable vehicles produced by GM, had called for production of the current models to end at its plant in Arlington, Texas, this week. After a retooling process, the redesigned SUVs were slated to begin production late in the month of April. In an email to suppliers viewed by Reuters and confirmed as authentic by GM, the automaker also said it was suspending development work on six future vehicle programs, including updates of the Chevrolet Equinox, GMC Terrain, Cadillac XT4, Bolt EV, Chevrolet Silverado and GMC Sierra. GM said preproduction work on those programs would be pushed back to calendar year 2021, with most of the updated vehicles scheduled to be launched as 2022 models. According to the Detroit News, work has also been paused on the Chevy Camaro and a future version of the Corvette that has yet to be unveiled and wasn't planned for production during the 2020 calendar year. Last week, the automaker told employees and suppliers it was delaying work on some future vehicles while pushing ahead with near-term models such as its redesigned full-size SUVs and the GMC Hummer EV, Cadillac Lyriq, Chevrolet Bolt EUV and Cruise Origin, as well as its new Ultium battery system. A GM spokesman who spoke with Reuters reiterated on Monday what the automaker had said last week — that the situation with its U.S. plants was "fluid" and that the automaker would "continue to evaluate" whether and when to reopen those plants on a week-by-week basis, with "employee safety" guiding that decision. GM said previously that it was closing most of its U.S. plants indefinitely. In its Monday email, GM asked suppliers to stop work on all pre-production tooling and pre-production parts manufacturing, but also not to dispose of any tooling or materials. GM told Reuters it had solicited volunteers from its workforce to finish the build-out of the current SUVs on a single shift in Arlington.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
