Rotary and Hybrid Engines Highlight Winners of 2004 Ward's 10 Best Engines

SOUTHFIELD, Mich., Dec. 9, 2003 -- Two unique and unusual engine "formats" headline the winners of Ward's 10 Best Engines awards for 2004, a highly anticipated auto industry award competition that for a decade has served as the auto industry's most-recognized barometer of powertrain-related product development.

Ward's 2004 list of honored engines marks the tenth anniversary for the Ward's 10 Best Engines awards.

Mazda Motor Corp.'s all-new Renesis rotary engine and Toyota Motor Corp.'s more-powerful hybrid-electric Prius drivetrain are two non-traditional engine systems winning Ward's 10 Best Engines honors for 2004. Renesis is the exhilarating new iteration of the rotary engine design to which Mazda alone has remained devoted since the company's first production engine in 1967. Mazda has over the years launched successive new generations of its innovative rotary, and the Renesis brings significant and exciting new improvements to the design.

Ward's 10 Best Engines judges this year also reward another non- traditional engine design, Toyota's Prius hybrid-electric drivetrain that combines several high-tech components into a gasoline-electric "system" that delivers high mileage, excellent responsiveness and remarkably low emissions. Toyota's hybrid "system" is comprised of a small, highly efficient 4-cylinder gasoline engine, an electric motor to enhance the gasoline engine's power and a continuously variable transmission. A sophisticated powertrain-control unit leverages the best attributes of each component.

Fuji Heavy Industries' Subaru arm earns its first spot on the Ward's 10 Best Engines list with its high-performance horizontally opposed "boxer" 4- cyl., which powers the critically acclaimed Subaru WRX STi. The turbocharged boxer engine delivers one of the highest horsepower-per-liter ratings of any engine available in the U.S., making it unusually powerful in relation to its size -- an attribute always appreciated by Ward's 10 Best Engines editor- judges.

Rounding out the new entrants to the 10 Best Engines list is Audi AG with its power- and technology-laden 4.2L DOHC V-8, which powers the special S4 variant of the company's A4 compact sedan/wagon lineup. The thrusty Audi V-8 produces 340 horsepower and 302 lb.-ft. of torque, making it one of the market's most powerful V-8s.

Trucks and SUVs continue to account for a significant portion of the U.S. market, and engines powering those types of vehicles are well-represented in the 2004 Ward's 10 Best Engines. A significant first-time winner is DaimlerChrysler AG's 5.9L inline 6-cyl. turbodiesel, developed in conjunction with and made by well-known diesel engine maker Cummins Inc. The new Cummins 600 turbodiesel is the standard engine for DC's Ram Heavy Duty pickup line and is the most powerful diesel engine available in the segment.

Two truck/SUV engines returning as Ward's 10 Best Engines winners are General Motors Corp.'s outstanding Vortec 4.2L dual-overhead-cam inline 6-cyl. and DC's 5.7L Hemi Magnum V-8. Both engines are emerging as stalwart winners on the Ward's 10 Best Engines list and the Hemi "Definitely is the best- marketed, best-advertised engine in the industry," says Bill Visnic, Ward's senior technical editor.

Six-cylinder engines, the most popular choice of U.S. vehicle buyers, are represented by Nissan Motor Co.'s "VQ" 3.5L DOHC V-6, the only engine to win a Ward's 10 Best award each year in the competition's decade-long history, Honda Motor Co. Ltd.'s 3L DOHC V-6 available in the Accord and BMW AG's renowned 3.2L inline 6-cyl. found in its M3 coupe and convertible.

  The Ward's 10 Best Engines for 2004:

  Engine (and tested vehicle)

  *  Audi AG 4.2L DOHC V-8 (S4)
  *  BMW AG 3.2L DOHC I-6 (M3)
  *  DaimlerChrysler AG 5.7L Hemi Magnum OHV V-8 (Dodge Ram)
  *  DaimlerChrysler AG 5.9L Cummins 600 OHV I-6 turbodiesel (Dodge Ram
      Heavy Duty)
  *  Fuji Heavy Industries Ltd. Subaru 2.5L DOHC turbocharged H-4 (Subaru
      WRX STi)
  *  General Motors Corp. Vortec 4.2L DOHC I-6 (GMC Envoy)
  *  Honda Motor Co. Ltd. 3L DOHC V-6 (Accord Coupe)
  *  Mazda Motor Corp. 1.3L Renesis rotary (RX-8)
  *  Nissan Motor Co. Ltd. 3.5L DOHC V-6 (Infiniti G35)
  *  Toyota Motor Corp. 1.5L DOHC I-4 Hybrid (Prius)

Five of 2004's 10 Best Engines are first-time winners, which Visnic says symbolizes the increasing fractionalization of the U.S. vehicle market -- and highlights the intense competitive pressures at work on the auto industry's powertrain developers and engineers.

"Multi-year 10 Best Engines winners may become more rare," says Visnic. "Powertrain-development cycles, just like those for the entire vehicle, are becoming increasingly more compressed. The effect will be obvious: We'll see more new or revised engines coming to market more often."

On the tenth anniversary of the Ward's 10 Best Engines competition, this year's winners show more diversity than at any time in the past, Visnic adds. "The 'spread' of engine types -- and even the vehicles they power -- is refreshingly distinct. This year's list includes a high-mileage, eco-friendly hybrid system arm-in-arm with several powerful V-8s. And although performance-oriented engines always enjoy a certain edge with Best Engines judges, the reality is that because most of these engines power vehicles that can essentially be considered 'mainstream,' there has never been so much engine performance available to buyers of reasonably common vehicles."

Visnic stresses that the most relevant aspect of the Ward's 10 Best Engines list may be that it highlights the crucial relationship between engines and vehicles that are successful in the market. "A Best Engines mantra essentially has emerged over a decade of presenting these awards," says Visnic. "It's simple. With very few exceptions, each and every 10 Best Engines winner over the past decade has powered a commercially successful vehicle. We are convinced that is no coincidence."

During a two-month test period, six editors from Ward's Communications evaluated the engines "nominated" from 32 different cars, trucks and SUVs. Scoring encompassed the crucial engine characteristics of power, torque, noise, vibration and harshness (NVH), technical relevance and basic comparative numbers. All engines nominated and tested were in vehicles with a base MSRP under $52,500. "The engines in high-priced vehicles should be outstanding," says Visnic. "By setting a realistic base price, we ensure the awards have value and relevance to the average consumer."
