Bosch Supplies Engine Technology on 8 of Ward's 10 Best Engines


-- The Volkswagen Jetta TDI returns for the third consecutive year, contains Bosch clean diesel technologies
-- Seven winning engines contain Bosch gasoline system technology
-- Bosch diesel technology highlighted on Ward's Diesel Shootout Winner

Bosch supplies advanced technology to eight of the Ward's 10 Best Engines of 2011, including engine management system and components supporting diesel, gasoline direct and port fuel injection.

"Bosch is committed to creating quality technologies, including a variety of powertrain options, that help automakers deliver the most fuel efficient, safe and convenient vehicles to market, while benefitting consumers and the environment," said Peter Marks, chairman, president and CEO, Robert Bosch LLC.

The Volkswagen Jetta TDI engine was named the 'dean' of Ward's 10 Best Engines of 2011. The award-winning engine features Bosch's common rail system, including fuel injectors and high pressure fuel pumps. The Volkswagen's 2.0-liter DOHC Turbodiesel is one of only two direct carryover engines from the 2010 list, and the only engine to receive the award three consecutive years, earning the designation of the 'dean' of Ward's list.

In addition to supporting Volkswagen on their 2.0-liter TDI engine, for each of the following seven gasoline-powered award winners, Bosch has varying content that may include engine control units, direct- and port-fuel injectors, high pressure pumps, oxygen and other powertrain sensors, as well as other technologies, such as ignition coils, starters and coolant pumps:

-- 3.6-liter Pentastar DOHC V-6 (Dodge Avenger)
-- 5.0-liter DOHC V-8 (Ford Mustang GT)
-- 1.4-liter DOHC I-4/111kW drive motor (Chevrolet Volt)
-- 3.0-liter N55 Turbocharged DOHC I-6 (BMW 335i)
-- 1.6-liter Turbocharged DOHC I-4 (Mini Cooper S)
-- 3.0-liter TFSI Supercharged DOHC V-6 (Audi S4)
-- 3.0-liter Turbocharged DOHC I-6 (Volvo S60)

"Bosch has developed and continues to make advancements in gasoline engine technologies to improve the efficiency of the internal combustion engine, as it will remain the dominant powertrain for the next 20 years," said Sujit Jain, regional president, Gasoline Systems North America, Robert Bosch LLC. "A number of these advancements can be found on both gasoline-direct and port-fuel injection engines named to this year's list."

Diesel Common Rail System Improves Fuel Economy, Reduces Emissions, Contributes to Resale Value

Bosch's diesel engine technology consists of controlled high-pressure common rail and unit injector systems. Bosch's robust injection process boosts fuel economy by an average 30 percent and increases torque by 50 percent, while reducing carbon dioxide emissions by nearly 25 percent. Additionally, clean diesel passenger vehicles have up to 30 percent higher residual value than their gasoline counterparts which contributes significantly to the total cost of ownership.

Ward's 'Diesel Shootout' Highlights Bosch Clean Diesel Technology

Additionally, Bosch will be acknowledged during the Ward's event for supplying clean diesel technologies to the shootout's three participants: the Cummins 6.7-liter I-6 in the Ram Laramie 2500 HD, the Duramax 6.6-liter V-8 in the GMC Sierra Denali HD, and the winner of the first-ever "Diesel Shootout," the Ford F-250 Super Duty Lariat, with the advanced Power Stroke® 6.7-liter V-8 engine.

Bosch hosted the "Diesel Shootout" event on July 28, 2010, to put these three diesel engines to the test. Ward's Automotive Group and Fleet Owner put the trucks, each towing 10,000-pound loads, through a series of maneuvers designed to evaluate the engines based on acceleration, engine technology, fuel efficiency, drivability, and overall power while also monitoring noise, vibration and harshness levels at idle, cruising speed and during hard acceleration. The competition followed the format of Ward's 10 Best Engines and also focused on towing capacity, which has not traditionally been part of the best engines evaluations.

Bosch's Flat Rock Proving Ground provided state-of-the-art testing for a variety of innovative automotive technologies. To keep a level playing field, all three trucks featured Bosch's diesel common rail systems and the trucks were roughly the same three-quarter-ton, 4X4 turbodiesel crew cans with automatic transmissions and axle ratios of about 3.73.

"Clean diesel technology plays a major role in helping to increase the performance of heavy-duty vehicles without sacrificing great fuel economy," said Bernd Boisten, regional president, diesel systems, Robert Bosch LLC.

"Clean diesel technology is a perfect solution for pickup trucks and we expect to see this technology continue to gain momentum in this segment in the coming years," Boisten added.
