McLaren and Alonso will use Chevy engines at Indy 500

Fernando Alonso will have a Chevrolet engine in his McLaren when the double Formula One champion attempts to win next year's Indianapolis 500 in his second attempt, the British team announced on Tuesday. The 37-year-old Spaniard led 27 laps last year on his debut at The Brickyard in a Honda-powered Andretti Autosport car before retiring with an engine problem with 21 laps to go. The 2018 Indy 500 winner, Australian Will Power, won with Chevrolet-powered Team Penske last May. "Having Chevrolet power behind me means we're putting ourselves in the best possible position to compete at the front," said Alonso in a McLaren statement. The double Monaco Grand Prix winner, who won the Le Mans 24 Hours with Toyota this year, left Formula One at the end of the season last month and is targeting Indianapolis as the final part of the "Triple Crown of Motorsport": winning the Formula One championship (or Monaco), Le Mans and the Indy 500. The late Briton Graham Hill, also a two-times Formula One champion who died in 1975, is the only one to have done it, completing the triple in 1972.Reporting by Alan BaldwinRelated Video: Motorsports Chevrolet McLaren Racing Vehicles IndyCar

2016 Chevy Volt will start at $33,995*

One of the biggest mysteries regarding the 2016 Chevy Volt has been revealed. Chevy announced today that the next-gen plug-in hybrid will have an MSRP of $33,995, which includes GM's $825 destination fee. That's a few hundred dollars less than the current Volt, which has an MSRP of $34,170. The second-gen Volt is about more than a price cut, though. The car has an increased all-electric range (50 miles vs. 38 in the current model) and better fuel economy. Once the battery power runs out – which it doesn't do, in most situations, since 90 percent of all trips are electric-only – the no-longer-premium-only gas engine offers 41 miles per gallon, up from 37 mpg. We know most buyers are price-conscious, and with the still-available federal tax incentive of up to $7,500, the new Volt can be had for $26,495. That should put a spring back into sluggish Volt sales, which are down 46 percent year-over-year so far in 2015. Through the end of April, GM has sold a cumulative 76,136 first-gen Volts since introducing the car in 2010. Chevrolet Announces 2016 Volt Pricing Next Gen delivers more technology at new price as low as $26,495 DETROIT – The Chevrolet Volt is poised to continue to bring new owners to the electric plug-in family. Pricing will be as low as $26,495 after the full federal tax credit of $7,500. (Federal tax credit can range from $0 up to $7,500.) In California, the vehicle's largest market, residents of the state will be able to purchase the all-new Volt for as low as $24,995 after state and Federal incentives. The 2016 model will start at $33,995 MSRP, including an $825 destination fee (excluding tax, title, license and dealer fees). This is almost $1,200 less than the current generation Volt. "The next generation Chevrolet Volt delivers more technology, the ability to drive further between gas fill ups and now with even more value to our customers. It's what our loyal Volt owners told us they wanted," said Steve Majoros, Director, Chevrolet Marketing. "We are confident we will continue to attract new customers to Volt with the vehicle's product improvements and attractive price." The Volt continues to be a success with the brand with nearly 70 percent of Volt owners trading in a non-GM product or adding to their household fleet in 2014, the highest of any Chevy nameplate. The number one trade-in for the Volt is the Toyota Prius. To date more than 75,000 first generation Volt owners have driven hundreds of millions of EV miles.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
