GM drops price of Spark EV to $25,995; lease to $139/month

The drive to lower EV prices continues. GM announced today that the base model 2015 Chevy Spark EV 1LT would get a price cut to $25,995. That's $1,500 less than it used to be but the bigger news might be the lowered lease price. Instead of $199 a month, all that Chevy is asking for to get you into an all-electric Spark now is $139 a month (39 months, with no money due at signing), down from the 36-month, $199-a-month lease cost with a $999 down payment. Sadly, the number of states where the Spark EV can be bought is almost as small as the lease payment: the car is available only in California, Oregon and Maryland (well, Maryland won't be ready until the summer). GM is doing more than just lowering the MSRP. On top of the federal and state tax incentives available, GM is offering bonus cash in all three states ($1,000 in California, $1,200 in Maryland, and $3,500 in Oregon). If you're wondering why those numbers vary so much, take a look at the already-available state EV incentives in play: California offers $2,500 and Maryland $2,300. Somehow, they all balance out. If you do some addition with the $7,500 federal tax credit, you see that the Spark EV can be had for $11,000 off the MSRP no matter where you buy. If you qualify for everything, $14,995 is a darn good deal for an EV, especially one as fun as the Spark.

Depending on an individual's tax situation, the Spark EV is eligible for federal tax credit up to $7,500. "Chevrolet is committed to making EV driving more accessible, affordable and fun" said Steve Majoros, director of Chevrolet Car and Crossover Marketing. "The Spark EV is already the most efficient – and one of the most affordable – EVs you can buy. 2015 Spark EV customers will benefit from an impressive blend of technology, capability and low cost of ownership, now at an even more impressive price." California and Maryland Spark EV owners may also qualify for a $2,500 California state rebate or $2,300 Maryland excise tax exemption. Additional Chevrolet bonus cash is also available: $1,000 in California, $1,200 in Maryland, and $3,500 in Oregon. After full federal and state tax credits and Chevrolet bonus cash, the Spark EV could be as low as $14,995.

'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).

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.
