FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Waymo bids its self-driving bubble cars farewell

Say goodbye to Waymo's quirky bubble-shaped autonomous cars. Google's former self-driving car division is retiring its fleet of "Fireflies" - also known as "koalas" and "gumdrops," among many other nicknames - to focus on integrating its technology into more traditional vehicles. It particularly aims to give more people access to its self-driving technology through a fleet of 600 Chrysler Pacifica minivans, which the team has equipped with its latest custom-built radar, lidar and vision systems. The minivans also come with Waymo's newest AI platform that can see farther and more clearly. Plus, they run like normal vehicles do, unlike the Fireflies, which are limited to 25mph. This move doesn't exactly come as a surprise. A report from late 2016 said Alphabet's Larry Page scrapped Waymo's plans to manufacture bubble-shaped driverless vehicles to make the company's strategy more feasible. It said Page's new plan involves collaborating with automakers to design and make cars with no pedals and steering wheels that use Google's self-driving tech. Shortly after that report came out, Waymo introduced its heavily modified Chrysler Pacificas with altered electrical, powertrain, chassis and structural system to accommodate the extra weight of the company's equipment. While Waymo will no longer use its Fireflies for future tests, you can still catch a glimpse of the cute bubble cars in various locations. This August, they'll be on display at the Arizona Science Center in Phoenix before making their way to the The Thinkery in Austin, Texas, this October. You'll also find a Firefly at the Computer History Museum in Mountain View, California and another at the Design Museum in London.Written by Mariella Moon for Engadget. Waymo Related Video:

Treasury says auto bailout tally drops to $20.3 billion

In December, the US Treasury announced that it was going to sell all of its shares in General Motors within 12 to 15 months. The first tranche of the 500-million total shares was purchased by GM, which took 200 million of them at $27.50 per share. That price represents an eight-percent premium over the market price at the time. The remaining 300 million shares will be sold "through various means in an orderly fashion."
Of the $418 billion disbursed through the Troubled Asset Relief Program (TARP), a report in Automotive News indicates that "about 93 percent" has been paid back, and the latest figures put Treasury's loss from the program overall at $55.58 billion. That's a $4.1 billion improvement on the last figure, when the expected red ink added up to $59.68 billion. The auto industry's portion of that loss is estimated to be $20.3 billion, a 16-percent drop from the earlier estimate of $24.3 billion.
The Treasury now owns 19 percent of GM, but if all goes well, there will be no more cause for anyone to utter "Government Motors" by the end of Q1 next year. A loss of some kind is still expected, however. Although GM's stock price is close to $29 at the time of this writing, that's still $4 below its IPO price and well below the $72 share price necessary for the government to come out even on its GM investment. On second thought, maybe the ribbing will continue.
