Bentley Continental GT V8 and Toyota 4Runner | Autoblog Podcast #604

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski and Senior Editor, Green, John Beltz Snyder. First, they talk about driving the 2020 Bentley Continental GT V8 First Edition, followed by the 2020 Toyota 4Runner TRD Off-Road. Then they revive a format called "This or That," discussing the Jeep Wrangler vs. Gladiator, Subaru Forester vs. Outback, Mustang vs. Camaro vs. Challenger, and whether they'd rather spend $25,000 on a new or vintage car. They've got an update on a previous Spend My Money segment, and, finally, they help another listener pick a daily driver.

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.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.
