Acura Announces Clean Diesel Engine for 2009


Turbocharged i-DTEC engine at NAIAS

The new CAFE standards have caused quite a stir in the USA, in both a good and bad sense. Its a good thing that US cars need to become more fuel efficient with less emissions, and one way of reaching this goal is clean diesel.

Diesel is of course notoriously known for its polluting, but over the past years the cleaning filters have been researched and developed at an amazing pace. Acura has not been sitting still either and has announced at the Detroit Motor Show that the marque will offer a clean diesel turbocharged i-DTEC engine by 2009.

The first car to be powered by the new engine has not yet been announced.









Press Release

Acura Will Introduce Clean Diesel i-DTEC Engine in 2009

Turbocharged i-DTEC Engine Displayed at the North American International Auto Show

Acura will introduce the new i-DTEC clean diesel engine to the North American market in 2009. The i-DTEC engine reduces noxious exhaust emissions while boosting power and fuel efficiency. A combination of optimized combustion chamber design and reduced injection time results in a clean, quiet engine that delivers excellent performance for an enjoyable driving experience. In addition, the i-DTEC engine meets the ultra-stringent U.S. EPA Tier II Bin 5 emission standards without the on-board storage of urea.

The i-DTEC clean diesel engine is on display exclusively in the Acura booth at the North American International Auto Show and will be utilized in an Acura vehicle to be named at a later date.

Porsche Panamera Hybrid Schematics Released


Full parallel hybrid

The Porsche Panamera will have to hit the ground running at the end of the decade in order to compete with the Aston Martin Rapide, Mercedes CLS, BMW 8-Series and in the lower regions of the four-door GT class, the VW Passat Coupe. One major selling point for the Panamera might become the availability of a full parallel hybrid engine, offering consumption of less than 9 liter per 100 kilometers.

The newly developed full parallel hybrid system is based on the current Porsche Cayenne Hybrid will consist primarely of the battery unit in the luggage compartment, power electronics, and an additional clutch and electric motor between the engine and transmission. This set-up allows the car to be driven using the gasoline engine (classic Porsche sport style), electric engine (emissions free all-electric driving) or use them both as one power unit, combining the best of both worlds.

The Porsche Panamera will initially be offered with proven drivetrains in 2009 with a hybrid version following later, depending on market requirements.



Press Release

Hybrid Drive on the Porsche Panamera

Dr. Ing. h. c. F. Porsche AG, Stuttgart, will also be building a hybrid drive version of the new Panamera. This four-door Gran Turismo with sporting driving dynamics so typical of Porsche will boast the proven components featured in the Cayenne Hybrid entering the market at the end of the decade. And thanks to its newly developed full parallel hybrid, Porsche’s Sports Utility will offer average fuel consumption of less than 9 litres/100 kilometres.

The new Porsche Panamera will be the first four-door sports model to feature particularly fuel-efficient full parallel hybrid technology. At the same time the Panamera will also benefit from the experience then gained by the Porsche Cayenne as a pioneer in hybrid drive.

The newly developed full parallel hybrid system will consist primarily of the battery unit positioned in the luggage compartment, the power electronics, and the hybrid module between the engine and transmission comprising an additional clutch and the electric motor. Depending on driving conditions, the hybrid module is able to disengage either the combustion engine or the electric motor, or to combine both drive systems as one joint power unit. Hence, the Panamera may be driven in a number of different modes ranging from all-electric drive absolutely free of emissions all the way to the sporting style of motoring so typical of a Porsche.

The fourth model series coming from the sports car manufacturer in Stuttgart also boasts other striking features, the wide and low body offering dynamic proportions and muscular design for an outstandingly sporting and at the same time compact overall look.

The space available inside the car offers a brand-new experience of roominess. The two sporting and comfortable single seats at the rear will allow adults to relax with surprisingly generous headroom, in full comfort and, if they wish, with all the performance and speed of a genuine Gran Turismo.

Sitting in the elegant and modern cockpit with its high-quality materials, the driver will enjoy all the sporting and unmistakable driving dynamics so typical of every Porsche. The new Panamera Gran Turismo will be making its world debut in 2009 and will be introduced initially with proven drive concepts. The hybrid version will follow later, depending on market requirements.
