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.

2014 Cadillac XTS Vsport

Not long after bombing around the Milford Road Course in the new CTS Vsport, Cadillac invited me to try out its other new-for-2014 Vsport model: the XTS. And despite using the same twin-turbocharged 3.6-liter V6 from the CTS, the Vsport package takes on a whole new meaning here in Cadillac's softer flagship.
In the CTS, this trim perfectly bridges the gap between the standard models and the hardcore CTS-V, and is focused on being the best-driving version of the range without a standalone V badge. The XTS, however, has no proper V model, so the Vsport becomes the new range-topper for that line by default. But unlike the CTS Vsport, which uses rear-wheel-drive architecture and is focused on driving dynamics above all, the XTS is geared toward a much different customer.
The entire XTS experience is far more concerned with plush comfort than handling prowess, and while this Vsport model certainly ups the ante with more power and some mild suspension and steering tweaks, it's not exactly what we'd call a particularly engaging experience. But that doesn't mean it isn't good.

GM's Mark Reuss explains why a performance Cadillac ELR-V won't happen

Hey, I've got enough things to worry about. That's one interpretation of General Motors executive vice president Mark Reuss' response to a question posed by Driving the Nation about the recently-introduced Cadillac ELR plug-in hybrid. Reuss said GM will "definitely expand the tuning envelope" for the ELR. The question was whether GM would consider adding magnetic ride control to the quite-powerful-for-a-plug-in Caddy, creating an "ELR-V" model in the process. Reuss' non-answer: "Good question, can't really answer that," but then elaborated that magnetic ride control uses up "a lot" of power otherwise spoken for in terms of providing the longest electric-only range possible. Interestingly, he did add that GM will "definitely expand the tuning envelope" for the ELR, as you can see in the video below. With the model retailing for north of $75,000, fewer than 60 percent of US Cadillac dealers were carrying the ELR as of last month and just 99 ELRs were sold during the first two months of the year. In an effort to sell more vehicles, GM said in January that it would offer the ELR for a 39-month lease for $699 a month for qualified lessees and with a $5,999 down-payment required.
