How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.

We really want to use an eCrate to restomod an old GM car. Here's what we'd build

You hopefully saw the news today of GM's introduction of its Connect and Cruise eCrate motor and battery package, which effectively makes the Bolt's electric motor, battery pack and myriad other elements available to, ah, bolt into a different vehicle. It's the same concept as installing a gasoline-powered crate motor into a classic car, but with electricity and stuff.  This, of course, got us thinking about what we'd stuff the eCrate into. Before we got too ahead of ourselves, however, we discovered that the eCrate battery pack is literally the Bolt EV pack in not only capacity but size and shape. In other words, you need to have enough space in the vehicle to place and/or stuff roughly 60% of a Chevy Bolt's length. It's not a big car, but that's still an awful lot of real estate. There's a reason GM chose to simply plop the pack into the bed and cargo area of old full-size SUVs. Well that, and having a rear suspension beefy enough to handle about 1,000 pounds of batteries.  So after that buzz kill, we still wanted to peruse the GM back catalog for classics we'd love to see transformed into an electric restomod that might be able to swallow all that battery ... maybe ... possibly ... whatever, saws and blow torches exist for a reason.  1971 Buick Riviera Consumer Editor Jeremy Korzeniewski: If you’re going to build an electric conversion, why not do it with style? ThatÂ’s why IÂ’m choosing a 1971-1973 Buick Riviera. You know, the one with the big glass boat-tail rear end that ends in a pointy V. Being a rather large vehicle with a big sloping fastback shape, IÂ’m hoping thereÂ’s enough room in the trunk and back seat to pack in the requisite battery pack. That would likely require cutting away some of the metal bulkhead that supports the rear seatback, but not so much that a wee bit of structural bracing couldnÂ’t shore things up. The big 455-cubic-inch Buick V8 up front will obviously have to go. Remember, this was the 1970s, so despite all that displacement, the Riviera only had around 250 horsepower (depending on the year and the trim level). So the electric motorÂ’s 200 horsepower and 266 pound-feet of torque ought to work as an acceptable replacement.   1982 Chevrolet S10 Associate Editor Byron Hurd: OK, so the name "E-10" is already taken by a completely different truck, but let's not let labels get in the way of a fun idea.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
