2015 Chrysler 200 gets 36 mpg with Tigershark four-cylinder

Chrysler has come out with the official fuel economy information on the new 200 following the info that was leaked from the EPA earlier this week. It turns out that our initial report of 18 miles per gallon in the city and 29 mpg on the highway for the all-wheel-drive V6 was correct.
What we didn't know at the time, though, was what sort of economy the 200's other powertrain options managed. Outfitted with the 2.4-liter four-pot, Chrysler is promising 23 mpg in the city and 36 mpg on the highway, with a combined rating of 28 mpg. Those figures are fairly impressive; besting figures of the 2.5-liter Ford Fusion and tying the 1.5-liter, EcoBoost, non-start-stop model. It's also beats the four-cylinder Toyota Camry's 35-mpg highway figure while tying its combined efficiency.
Stepping up to the 295-horsepower Pentastar V6 pushes the economy down to 19 mpg in the city, while the highway figure is a respectable 32 mpg for the front-driver. The combined rating for the FWD V6 is 23 mpg. Those figures can't quite match the 270-horsepower 2.0-liter, EcoBoost four of the Fusion, which nets 22 city and 33 highway. In fact, the V6 200 has trouble besting even the 3.5-liter V6 of the Camry, which returns 21 mpg city and 31 mpg highway. Again, though, the 200 is noticeably more powerful.

Waymo self-driving taxis in Arizona are now carrying paying passengers

CHANDLER, Ariz. — Alphabet's Waymo on Wednesday launched a significant development in its costly, decade-long quest for autonomous transportation: Its self-driving taxis are now actually generating fares. With little fanfare, the company has begun charging passengers to use its driverless vehicles in a roughly 100-mile (160 km) zone in four Phoenix suburbs — Chandler, Tempe, Mesa and Gilbert — where it has been testing its technology since 2016. Producing revenue is a strategic milestone, putting Waymo ahead of U.S. rivals, primarily General Motors' Cruise Automation and Uber Technologies, which have yet to launch their own paid self-driving services. All are racing to win customers and recoup billions spent developing the technology. To use Waymo's service, dubbed Waymo One, riders must download an app and provide a credit card number, similar to ride-sharing services Uber and Lyft. A human driver will be behind the wheel, but only to intervene in case of emergency. Major challenges remain, starting with technical hurdles. A Waymo One taxi tested by Reuters last week proved slow and jerky at times. Whether customers will continue using the service once the novelty wears off remains to be seen. Regulations governing the industry across the country are an incoherent patchwork, a significant hurdle to fast expansion. Waymo would not say exactly how many of its cars would be on the road in Arizona. It said its around-the-clock service initially would be limited to "hundreds" of people invited to sign up last year. For now, pricing is roughly in line with that of Uber and Lyft. A 15-minute, 3-mile (4.8 km) drive taken by Reuters last week cost $7.59, just above the $7.22 offered by Lyft. "Over time, we hope to make Waymo One available to even more members of the public," Chief Executive John Krafcik wrote in a blog on Wednesday. "Self-driving technology is new to many, so we're proceeding carefully." 10 million miles, $1 billion The company has been testing its driverless cars for a decade. Its fleet, now numbering 600 vehicles, has logged more than 10 million miles on public roads in and around 25 U.S. cities. Alphabet does not disclose its total investment, but industry experts put that sum at well over $1 billion. Monetizing driverless technology has been slow going.

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.
