Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000.

Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

Fires, deaths continue after Jeep fuel tank recall

As Kayla White slowed her SUV behind two other cars to exit a suburban Detroit freeway on Veterans Day, it was rammed from behind by a Cadillac STS. Her red 2003 Jeep Liberty bounced off a Nissan in front of it, rolled onto its side and exploded in flames. Other drivers ran to help but were forced back by the heat. Firefighters arrived in just three minutes but were too late. White, a 23-year-old restaurant hostess who was eight months pregnant, died of burns and smoke inhalation. White is one of more than 70 people killed in fires involving older Jeeps with plastic fuel tanks mounted behind the rear axle. Fiat Chrysler, which makes Jeeps, recalled 1.56 million of them in June 2013 under pressure from US safety regulators. But only 12 percent of the SUVs have been repaired in the 18 months since the recall, a much slower pace than usual. And White's Jeep was not among those fixed. Last week, prosecutors charged the Cadillac driver with committing a moving violation that caused a death. But safety advocates and the lawyer for White's family say the blame belongs as much, if not more, on Chrysler and an auto-industry safety system that moves too slowly to prevent tragedy. The rear-mounted tanks have little structure to protect them if struck from behind, making them susceptible to punctures and fires. Moving the gas tank in front of the axle would be expensive and difficult. So Chrysler's remedy involved installing trailer hitches on the rear of the Jeeps as an extra layer of protection. Government testing showed the hitches protected the tanks in crashes up to 40 mph when stationary Jeeps were hit from behind. But at higher speeds, they wouldn't help. White tried to get the repair done a few weeks before her death but was told by a Jeep dealer that parts weren't available, according to Gerald Thurswell, her family's lawyer. He wouldn't identify the dealership, and his contention could not be independently verified by The Associated Press. Thurswell contends the gas tank ruptured, spilling fuel that touched off the fire. A Chrysler spokesman expressed sympathy to White's family but said the company had no written proof that she asked a dealer about the recall. Two crash reconstruction experts interviewed by the AP say gas wouldn't have spilled from White's Jeep if the tank had been mounted in front of the rear axle. Both say a hitch might have prevented the tank from being damaged, but because both vehicles were in motion, neither expert could say for sure.
