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.

Hotter Cadillac ATS-V+ could use LS7 power

Rumor has it Cadillac is working on an even hotter version of the ATS-V, possibly called ATS-V+. And the latest intel from Motor Trend suggests this new model might have a great, big V8 under the hood. The V8 in question is the high-revving, naturally aspirated 7.0-liter LS7 from the Camaro Z/28. The hand-built engine makes 505 horsepower and 481 pound-feet of torque in the Z/28 – a nice increase over the 464 hp and 445 lb-ft in the standard ATS-V, which uses a twin-turbocharged 3.6-liter V6. Motor Trend says the ATS-V+ will come to market with an eight-speed automatic transmission, as well as the seven-speed manual 'box from the Corvette. A dual-clutch transmission will come to market later. Of course, we'll believe it when we see it. But an LS7-powered ATS-V sure sounds like a great package to us. Here's hoping.

What will the next Presidential limo look like?

With recent news that the Secret Service has begun soliciting proposals for a new armored limousine, we've been wondering what the next presidential limo might look like. The current machine, nicknamed "The Beast", has a design based on a car that's no longer sold: the Cadillac DTS. If General Motors gets the job again, which wouldn't be a surprise considering the government still owns a chunk of the company, the next limo's shape would likely resemble the new XTS (below, left). But Cadillac hasn't always been the go-to car company for presidential whips.
Lincoln has actually provided far more presidential limousines throughout history than Cadillac. In fact, the first car modified for Commander-in-Chief-carrying duty was a 1939 Lincoln K-Series called "Sunshine Special" used by Franklin D. Roosevelt, and the last Lincoln used by a president was a 1989 Town Car ordered for George H.W. Bush. If President Obama wanted a Lincoln today, it would likely be an amalgam of the MKS sedan and MKT crossover, as illustrated above.
And what about Chrysler? The only record we could find of a President favoring the Pentastar is Nixon, who reportedly ordered two limos from the company during his administration in the '70s, and then another one, known today as the "K-Car limo," in the '80s after he left office. Obama, however, has a personal - if modest - connection to Chryslers, having owned a 300 himself before he took office. A 300-based Beast (above, right) would certainly earn the U.S. some style points.
