BMW 320d

Whether the new BMW 320d EfficientDynamics has an automatic or manual transmission, in terms of sheer cost-effectiveness and dynamics it is impressive, delivering an average fuel consumption of 4.1 litres with emission figures of only 109 grams of CO2 per kilometre.
The 2.0-litre four-cylinder engine with BMW TwinPower Turbo technology originates from the same family as the BMW 320d and boasts a fully aluminium crankcase, a turbocharger with variable turbine geometry and the latest generation of common rail direct injection.
An optimised gear shift indicator helps you drive more economically and the higher overall gear ratio enables the new BMW 320d EfficientDynamics to operate with optimum fuel consumption at very low revs. Thanks to additional aerodynamic optimisation measures, such as the 5-spoke rims in Aero wheel design, tyres with reduced rolling resistance and the lowered chassis, the BMW 320d EfficientDynamics delivers an awe-inspiring power output of 120 kW (163 hp).

The BMW EfficientDynamics philosophy was key to the design of the BMW 3 Series Saloon. The aerodynamically optimised front apron and the underbody are particularly impressive, with their innovative new features that reduce drag and fuel consumption.
Embodying the BMW EfficientDynamics philosophy in a visible design feature is the front apron of the new BMW 3 Series Saloon. The integrated Aero Curtain guides the airstream along the front wheel housings via two vertical inlets. When accelarating, the stream of air then forms a “curtain” around the outer sides of the wheels. This curtain reduces turbulence and drag plus lowers fuel consumption.
The smooth underbody lining and the engine compartment screening further enhance the dynamics, they also provide improved acoustic insulation and corrosion protection.

Braking used to mean losing energy. Not any more. With Brake Energy Regeneration, as soon as you release the accelerator or apply the brake, the energy is used to charge the battery. This decreases the load on the engine, reduces emissions and saves fuel, which also means there’s more power available for acceleration.

The targeted generation of electrical energy has yet another advantage. At full acceleration, the engine has the propulsive force at its disposal that would be channelled off to charge the battery in conventional systems. So you enjoy an even more exhilarating experience.

 

 An intelligent lightweight construction reduces fuel consumption and improves performance in the new BMW 3 Series Saloon.
BMW engineers use a multitude of high-tech materials in the design of a BMW vehicle - lightweight materials such as aluminium in the front of the car and chassis and high-strength steel in the body together with ultra modern plastics. Engines and drive train components employ highly advanced magnesium alloys.
This intelligent lightweight construction lowers the weight of components by up to 25% and results in outstanding body stiffness and passive safety for drivers and passengers. It also improves the dynamic driving characteristics thanks to a balanced weight distribution between front and rear axles.

ALFA ROMEO TZ3 Stradale

The Alfa Romeo TZ3 Stradale by Zagato is based on the Viper ACR mechanical chassis with a carbon fibre body. "Bellezza necessaria" is the inspiration of this car which matches for the first time an USA power train and can represent the first American Alfa Romeo.

Following Zagato's gentlemen-driver heritage, TZ3 Corsa has been commissioned by the Alfa Romeo Zagato collector Martin Kapp. The first Alfa Romeo TZ3 Stradale has been delivered to the US Alfa Romeo and Zagato collector (and Saratoga Automobile Museum's board member) Eric King. The TZ3 Stradale n°2 and n°3 will be delivered in Japan and Europe.

Both TZ3 Corsa and TZ3 Stradale boast a typical Kamm-tail (K-tail) layout. This solution became famous in Italy with the "Coda Tronca" bodies which were tested by Zagato in the beginning of the 60s. They reached their apex on the Alfa Romeo TZ and TZ2. Kamm Effect is part of the functional design approach that aims to the aerodynamic efficiency. According to this, the CX can be lowered by keeping compact volumes at the same time. The reduction of the wind resistance is assured with the Kamm Tail design, without any need of a very stretched "drop" shape of the tail.
