Volvo XC60 T6 R Design

Volvo Car Corporation’s technological future is based on two in-house developed strategies. The first is a scalable vehicle architecture which, in principle, means most Volvo models can be built on the same production line irrespective of vehicle size and complexity. The second is a new engine range consisting solely of four-cylinder petrol and diesel engines.

We’ve liked the Volvo range very much. The 4 cylinder engines were a particular surprise. Volvos of old had 4 pot engines that wouldn’t pull the skin of a rice custard. They’ve come over all strong and butch.

The innovative programme also includes a new eight-speed automatic transmission as well as testing of a new Flywheel KERS (Kinetic Energy Recovery System) on public roads (later in 2011).

“We’re now taking our technological future into our own hands. Both our new architecture and the new engine range will enable us to be on par or even beat our toughest competitors in crucial areas such as driving dynamics and fuel efficiency,” says Peter Mertens, Senior Vice President Research and Development at the Volvo Car Corporation.

Own Scalable Platform Architecture
The Volvo Car Corporation is promoting economies of scale within the company’s own model range via a separate architecture for most of its products.

Within the new joint SPA (Scalable Platform Architecture) there are several platforms, groups of cars that share the same basic chassis structure, seat frame, electrical system and driveline.

These platforms are the basis for different vehicle clusters, that is to say a number of complete car models. In today’s model range, for instance, the Volvo S60, V60 and XC60 form one cluster.

It’s all about developing a model range consisting of cars based on the same joint modules and interfaces, scalable systems and components, and built in a flexible production system.

“SPA gives us a fresh technological start. When the first SPA model is launched in a few years’ time, about 90 percent of its components will be new and unique. What is more, we’re raising the bar when it comes to quality and technology level in every area. We will be fully on a par with the very toughest competitors,” says Peter Mertens.

In addition to the industrial benefits of common vehicle architecture there are also significant product related advantages: weight, electrification, driving dynamics and design proportions .

Weight reduction of 100-150 kg
With SPA, the Volvo Car Corporation takes the lead in automotive lightweight design. The highest degree of high strength steel qualities in the industry to date is combined with the extensive use of aluminium in the front structure, doors, chassis and powertrain.

This means that upcoming SPA models will be 100-150kg lighter than current models of the same size.

The new architecture enables electrification on all levels, from start/stop technology to pure electric drive, without intruding on interior space and load space.

New chassis technologies combined with lower weight and improved weight distribution will make it possible to compete with the very best when it comes to driving dynamics – without compromising ride comfort.

The electrical architecture enables all future multimedia and connectivity solutions – and it forms the backbone of the Volvo Car Corporation’s drive to reinforce its leading position in active safety.

New proportions promote exciting design
Overall packaging efficiency has been improved to support more attractive design proportions, while at the same time enabling significant improvements in aerodynamic drag.

Design limitations as regards to wheelbase, overhang, vehicle height and the height of the front are changed. This creates greater freedom to give forthcoming Volvo models more exciting lines.

“The proportions can give entirely different appearances even though the components used are exactly the same. The comparison between a donkey and a thoroughbred racehorse is an excellent example: each has a head, a body and four legs. But they are perceived entirely differently because of the proportions of their individual body parts and between their body parts,” explains Peter Horbury, Vice President Design at the Volvo Car Corporation.

“For us the new architecture means we can sharpen our design language still further, carving out just the right athletic and dynamic aura that is so important to the most demanding prestige car buyers. Concept You is an excellent example of this. It shows what can be achieved with the new architecture.”

Four-cylinder engines with the performance of today’s sixes
The new engine range, known as VEA (Volvo Environmental Architecture), consists solely of four-cylinder engines which in certain configurations will benefit from enhanced performance through electrification or other spearhead technology.

“It is time to stop counting cylinders. Focusing on four-cylinder engines is the perfect way to quickly reduce CO2 emissions and fuel consumption without compromising customer expectations on driving pleasure and performance,” comments Peter Mertens.

“We’re aiming to develop four-cylinder engines with higher performance than today’s sixcylinder units, along with lower fuel consumption than the current generation of four-cylinder engines.”

Reduction of parts, weight and fuel consumption
VEA is a modular range of diesel and petrol engines. Diesel common rail and petrol direct injection are standard. Several levels of turbo charging open up for flexibility that encompasses the whole range from high power and torque variants to fuel-efficient derivatives. In order to cover all customer requirements, certain engines will gain added performance via hybrid drive or other spearhead technology.

The modular format is based on a standard of 500cc per combustion chamber for optimum thermodynamics.

VEA offers several advantages: The number of unique parts is reduced by 60 percent. This promotes manufacturing efficiency, quality assurance and efficiency of new development projects. The new powertrains are
