Audi’s innovation: On-demand all-wheel drive. Subaru’s fast new car: the BRZ. Cheaper through synergy: Daimler introduces Highway Pilot Connect. Plus: SEAT’s new Leon Cupra 290, and classic and vintage cars at the Techno Classica in Essen.Present it! Audi A4 AllroadAudi introduced its Allroad Quattro in 2009. Now there's an off-road version based on the A4.Audi has renamed its "Quattro" system as "Quattro Ultra", to mark the change from permanent all-wheel drive to on-demand AWD. The new drivetrain system took around 5 years to develop. Sensors and a computer detect when a wheel might lose traction. Then the Ultra all-wheel drive engages -- within a quarter of a second!Taste it! Subaru BRZSubaru's BRZ is a true driving machine. BRZ stands for boxer engine, rear-wheel drive and zenith.By "zenith", the engineers mean they're convinced their achievement is tops. Its boxer engine, rear-wheel drive, low center of gravity and well-balanced weight distribution help the lightweight sports car handle like a dream on curves.Picture it! Daimler's Highway Pilot ConnectDaimler has added a new convoy function to its Highway Pilot autonomous driving system.Truckers can use Highway Pilot Connect to link up through WLAN to form a platoon or convoy. The system guides the self-driving tractor trailer rigs into a line with at least 15 meters between them. Driving in each others' slipstreams not only saves fuel; it also reduces the total road area taken up by the trucks. The autonomous driving technology also takes some of the strain off the trucker. Drive it! hops into the cab to check out the new technology first-hand. Test it! SEAT Leon Cupra ST 290SEAT's Cupra models are the cream of the crop among fans of sportiness and practicality.This year marks the 20th birthday of SEAT's fiery Cupra models. But the first Leon to bear the Cupra name appeared in the year 2000. At the time, nobody suspected that Leon would release its hottest model as a station wagon - much less that a 2.8-liter V6 with all-wheel drive could be so easily replaced by an even faster turbocharged, 2-liter engine with front-wheel drive.Vintage!

Hyundai i20 1.0 T-GDI - a fast, thrifty compact for young and old. The Volvo V60 station wagon - a beast of burden with a racecar heart. And: Bentley S2 Continental - the gentleman's express from the forward-looking ‘50s.

Audi’s combination of Quattro and the new Ultra Technology is a top performer – especially in everyday use. Prototypes consume about 0.3 liters less fuel per 100 kilometers than conventional all-wheelers.

The new fuel-efficient 3-cylinder, 74 kW, 1.0-T-GDI engine achieves a respectable top speed of 188 km/h at an official average fuel consumption of just 4.5 liters per 100 km. Does it appeal more to younger or older drivers?

Porsche's exhibition in Berlin, "The Future of Performance". It features seven vehicles, ranging from the beginnings in motor sports with the 550 Spyder to the present-day icon, the 918 Spyder with V8 engine and two electric motors.

A radiator grille like a castle, but elegant nonetheless: the 1959 Bentley S2 Continental Flying Spur. It’s a car-lover’s car, and the technology around the 6.2-liter V8 engine is solid.

Volvo’s V60 station wagon’s rising beltline and sloping A-line make it sleek. With the T6 gasoline engine and 225 kW, it’s sporty. But it’s more fuel-hungry than the manufacturer’s ratings.

Audi presents a new level of all-wheel drive. The combination of Quattro and new Ultra-Technology is supposed to achieve top results, especially under everyday conditions. Prototypes consume 0.3 liters less fuel per 100 km than conventional all-wheelers. To increase fuel efficiency, in standard operation the car works mostly with front-wheel drive.

Compacts like the i20 are popular among cost-conscious drivers. The new fuel-efficient three-cylinder 1.0-T-GDI engine delivers 74 kW and a top speed of 188 km/h - with fuel consumption officially averaging at just 4.5 liters per 100 km. Andre Zimmermann looks into whether the i20's design and equipment is more targeted at younger or more mature drivers.
