The new Volkswagen XL1 Super Efficient Vehicle (SEV)

The new Volkswagen XL1 Super Efficient Vehicle (SEV) has been unveiled at the Qatar Motor Show. Pioneering construction techniques, an advanced plug-in hybrid drivetrain and innovative packaging all play a part in allowing the XL1 to return 313 mpg on the combined cycle while emitting 24 g/km of CO2 to set a new benchmark for vehicle efficiency.

Powering the XL1 is a compact 800 cc TDI two-cylinder common rail diesel engine developing 48 PS. It’s linked to an electric motor producing 27 PS, resulting in a total of 75 PS – a modest output yet more than enough when the low kerb weight (795 kg) of the vehicle is taken into account.

The TDI engine is linked to an electric motor and a seven-speed DSG gearbox with an automatic clutch mounted between each unit. The electric motor can either work independently of the TDI engine or in tandem when accelerating. In pure electric mode the XL1 can travel up to 35 km before the diesel engine cuts in. Accelerating from rest to 62 mph can be achieved in 11.9 seconds; the electronically limited top speed is 99 mph.

In both its styling and packaging the XL1 draws on lessons learned from the 1-Litre car (2002) and the L1 concept (2009). The XL1 has evolved to feature staggered seating with the driver and passenger placed next to each other in a body structure made from advanced new materials providing immense strength yet weighing just 230 kg.

To make such weight savings possible, and yet viable for series production, Volkswagen developed and patented a new system for the manufacture of the Carbon Fibre Reinforced Polymer (CFRP) parts on the car called the Resin Transfer Moulding (RTM) process.

In total the XL1 weighs 795 kg. In addition to the body structure, the weight is accounted for by the drivetrain (227 kg), the running gear (153 kg), the interior including a pair of bucket seats (80 kg) and the electrical system (105 kg). In total just 23.2 per cent of the car (184 kg) is made out of either steel or iron.

Further savings are made through the extensive use of lightweight materials including magnesium (wheels), ceramics (brake discs) and aluminium (dampers, steering system, brake calipers).

The styling of the XL1 is borne out of functional requirements – easy access to the interior is granted via a pair of elegant scissor doors that hinge on the A-pillar while the profile of the car has been honed in the wind tunnel, the result being a remarkable coefficient of drag figure of 0.186. The XL1’s overall length (3,970 mm) and width (1,682 mm) are similar to those of a Volkswagen Polo yet its height (1,184 mm) is more akin to that of a Lamborghini Gallardo Spyder.

Although the XL1 is still very much a concept, its unveiling marks the next step towards the birth of a new class of Super Efficient Vehicles, while the advent of a process such as RTM is a significant milestone.

Driving without a driver: Volkswagen presents Temporary Auto Pilot

At the final presentation of the EU research project HAVEit (Highly Automated Vehicles for Intelligent Transport), Prof. Dr. Jürgen Leohold, Executive Director Volkswagen Group Research, has presented the “Temporary Auto Pilot” by Volkswagen: Monitored by the driver, the car can drive semi-automatically up to a speed of 130 kilometres per hour on motorways. It represents a link between today’s assistance systems and the vision of fully automatic driving.

“Above all, what we have achieved today is an important milestone on the path towards accident-free car driving,” emphasises Leohold at today’s final presentation of the EU research project HAVEit in the Swedish city of Borås. The Temporary Auto Pilot (TAP) bundles semi-automatic functions, i.e. functions monitored by the driver, with other driver assistance systems, such as ACC adaptive cruise control and the Lane Assist lane-keeping system into one comprehensive function. “Nonetheless, the driver always retains driving responsibility and is always in control,” continues Leohold. “The driver can override or deactivate the system at any time and must continually monitor it.”

TAP always offers the driver an optimal degree of automation as a function of the driving situation, acquisition of the surroundings and driver and system states. It is intended to prevent accidents due to driving errors by an inattentive, distracted driver. In the semi-automatic driving mode – referred to as Pilot Mode, for short – TAP maintains a safe distance to the vehicle ahead, drives at a speed selected by the driver, reduces this speed as necessary before a bend, and maintains the vehicle’s central position with respect to lane markers. The system also observes overtaking rules and speed limits. Stop and start driving manoeuvres in traffic jams are also automated. With TAP, it is possible to drive at speeds of up to 130 kilometres per hour on motorways or similar roads. Drivers must still continually focus their attention on the road, so that they can intervene in safety-critical situations at any time.

In contrast to previous research vehicles such as “Junior” and “Stanley”, TAP is based on a relatively production-like sensor platform, consisting of production-level radar-, camera-, and ultrasonic-based sensors supplemented by a laser scanner and an electronic horizon. “One conceivable scenario for its initial use might be in monotonous driving situations, e.g. in traffic jams or over sections of a driving route that are exceedingly speed-limited,” comments Leohold.

About HAVEit

The EU funded R&D project HAVEit (“Highly Automated Vehicles for Intelligent Transport”) was set up to develop research concepts and technologies for highly automated driving. This will help to reduce the drivers’ workload, prevent accidents, reduce environmental impact and make traffic safer. Launched in February 2008, 17 European partners from the automotive and supply sector and the scientific community collaborated on the project. Total investments in HAVEit amounted to EUR 28 million. EUR 17 million of this sum came from EU grants, and EUR 11 million was contributed by the 17 project partners, of which EUR 7 million was invested by the automobile industry.

The HAVEit consortium consists of vehicle manufacturers, automotive suppliers and scientific institutes from Germany, Sweden, France, Austria, Switzerland, Greece and Hungary:

Continental, Volvo Technology AB, Volkswagen AG, EFKON AG, Sick AG, Haldex Brake Products AB, Knowllence, Explinovo GmbH, German Aerospace Center (DLR), Ecole Polytechnique Fédérale de Lausanne (EPFL), University of Athens, Institute of Communications and Computer Systems (ICCS), University of Applied Sciences Amberg-Weiden, Budapest University of Technology and Economics, Universität Stuttgart, Institut für Luftfahrtsysteme, Wuerzburg Institute of Traffic Sciences GmbH, Institut National de Recherche en Informatique et en Automatique (Inria), Institut français des sciences et technologies des transports, de l'aménagement et des réseaux (IFSTTAR).

Heritage - Our proud past - our exciting future

Naturally, we're very proud of our heritage - few car manufacturers have produced so many legendary cars as Volkswagen. The Beetle, whose spirit lives on in our beautiful New Beetle and the Golf, our modern masterpiece.

The concept of the Volkswagen - the people's car - was created in 1934 by Ferdinand Porsche as an affordable and reliable means of transport for everyone. Since those early days the company has developed to become a major global force in car manufacturing.

We think the best way to honour our past is to invest in the future. Which is why you'll find Volkswagen at the forefront of pioneering developments in design, technology and environmental initiatives.
