Fuel-Saving Engine Stop-Start (ESS) Technology Now Standard with V6 in Award-Winning Jeep Cherokee and I-4 in All-New 2015 Chrysler 200
Chrysler Group is offering fuel-saving Engine Stop-Start (ESS) technology as standard equipment on certain models of the award-winning 2015 Jeep® Cherokee mid-size SUV and all-new 2015 Chrysler 200 mid-size sedan.
Chrysler 200 customers who opt for the 2.4-litre Tigershark MultiAir® I-4, and Jeep Cherokee customers who choose the available 3.2-litre PentastarTM VVT V6, will experience estimated fuel-economy improvements of up to three per cent, compared with the conventional vehicle-engine pairings.
ESS applications in the Chrysler 200 and Jeep Cherokee will account for an estimated C02 emissions-reduction of up to three per cent.
The technology made its NAFTA-region debut in the Ram 1500 full-size pickup, the most fuel-efficient truck in its segment. Availability in the popular Jeep Cherokee is scheduled for third quarter. ESS arrives the following quarter in the all-new Chrysler 200.
The all-new 2015 Chrysler 200 is the world’s first mid-size sedan to feature a nine-speed automatic transmission, which comes standard and contributes to a fuel-economy gain of up to 26 per cent compared with the outgoing car and its four-speed gearbox.
The high-tech transmission – which also comes standard in the Jeep Cherokee – dispenses power smoothly for elevated refinement. Such performance is made possible because the ratio steps between its gears are smaller than those of other transmissions.
The Cherokee’s available 271-hp 3.2-litre Pentastar VVT V6 is derived from the acclaimed 3.6-litre Pentastar VVT V6, named three times one of Ward’s 10 Best Engines.
Individual exhaust-manifold runners are integrated into the aluminum cylinder-head casting, a key Pentastar-family differentiator. This design feature reduces weight and affords packaging benefits.
The 24-valve engine’s 10.7:1 compression ratio aids in lowering fuel consumption and improves performance while its variable-displacement oil pump further reduces parasitic losses to maximize fuel economy. The pump is programmed to operate as needed, staying in low-pressure mode below 3,500 rpm, and then bumping up pressure as demand follows engine-speed.
The Jeep Cherokee has earned multiple media accolades, from the 2014 Canadian Utility Vehicle of the Year, courtesy of the Automobile Journalists Association of Canada (AJAC) to the Rocky Mountain Automotive Press Association’s SUV of the Year.
