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.

Cadillac calling in 4,900 CTS-V models for brake issue

General Motors is recalling just over 4,900 first-generation Cadillac CTS-V sedans built between September 6, 2003 and June 11, 2007. The affected vehicles are largely registered in cold weather states where rock salt is used on roads. The salt could corrode the front brake hose's fitting in the brake calipers, which could lead to a brake fluid leak, the National Highway Traffic Safety Administration's bulletin reads. Needless to say, that would make slowing down the Corvette-powered Caddy a challenge. The affected vehicles were registered and/or sold in the following states: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. GM is set to begin notifying owners of the affected vehicles, who will need to report to dealers to have both front brake hose assemblies replaced. Repairs are, naturally, free of charge. Scroll down for the official NHTSA bulletin. Report Receipt Date: APR 15, 2015 NHTSA Campaign Number: 15V225000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 4,907 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured between September 6, 2003, and June 11, 2007, currently registered, or originally sold, in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. In the affected vehicles, snow or water containing road salt or other contaminants may corrode the front brake hose fitting at the caliper. CONSEQUENCE: Corrosion may cause the brake system to leak which could lengthen the distance needed to stop the vehicle and increase the risk of a crash. REMEDY: GM will notify owners, and dealers will replace both front brake hose assemblies, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 15149. Note: This recall is an expansion of recall 10V-105. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Cadillac CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.
