Volvo’s Drive-E powertrains offer power, efficiency

Volvo Cars' new Drive-E range of powertrains takes efficient driving pleasure to a new dimension in which the number of cylinders is no longer important to describe power and drivability. The first three engines from the two-litre, four-cylinder Drive-E powertrain family will be launched in autumn 2013. The diesel version features world-first i-Art technology, and the most powerful petrol version comes with a class-leading combination of a compressor and a turbocharger. (Volvo photo)

 “The launch of our new Drive-E powertrains is an important step in Volvo’s product investment plan that will result in a stronger, more competitive position in the marketplace,” said Volvo Cars of North America President and CEO John Maloney. “A great deal of research went into learning how our customers drive and these highly efficient, low-emission engines were designed to provide greater customer choice while retaining the performance attributes our customers expect.”

Drive-E is now Volvo’s ecological moniker for all innovations reducing environmental impact from sustainable, efficient and clean manufacturing process, recyclable materials, low-emission powertrains.

Powertrains Deliver Efficient Power

Drive-E powertrains are said to deliver what was previously thought possible from 6 or 8 cylinders motors. The engines can be used later in electric vehicle purposing or hybrid applications.

The engineers dropped the overall weight 100 pounds, which they say also lowers emissions while raising economy, depending upon the engine from 13 to 26 percent. Exact numbers have not be released yet.

The Drive-E engine range consists of just two 4-cylinder engines, one common rail diesel and one direct-injected gasoline version, that replaces 8 engine architectures across three three platforms. Both the diesel and the gasoline versions share the same architecture.

 Two gasoline Drive-E engines will be offered in the US:

  • a 240-horsepower version
  • a high performance 302-horsepower version.

In the United States, Volvo will continue to offer its current lineup of AWD powertrains, along with Drive-E. As a result, U.S. customers can choose between the new engines and some current engines until Volvo transitions solely to Drive-E.

Technical Features

The new engine family reflects thoughtful design features to maximize the engine’s efficiency, as well as provide dynamic drivability and performance. Drive-E powertrains offer many technical features:

  • Friction reduction: Friction-reduction measures have been employed throughout the engine, including ball bearings on the camshaft, high-speed continuous variable valve timing and intelligent heat management with a fully variable electric water pump.
  • Start-Stop and Brake Regeneration: All Drive-E engines feature start-stop and brake regeneration. The technology uses brake pressure measurement to trigger when to stop and start the engine. The start/stop system is programmed to shut down the engine immediately when the car reaches a standstill. An electric pump keeps oil pressure up while the engine is stopped.
  • Turbo Only or Turbo and Supercharger: Using the supercharger to boost the low end torque gives the gas-powered 302-horsepower T6 engine a big, naturally aspirated feel. The mechanically linked compressor functions immediately at low revs, while the turbocharger kicks in when the airflow builds up.
  • 8-speed gearbox: To deliver the desired responsive, smooth and fuel-efficient drivability, the engines are teamed either with a new eight-speed automatic gearbox tuned for improved efficiency.

Drive-E engines are prepared for future electrification from the start. Key components, such as the integrated starter generator, can be connected easily — and the compact size of the 4-cylinder engines means that the electric motor can be fitted in the front or rear of the vehicle. The battery pack will be located in the center of the car.
