  • Audi’s electrified future.

    The introduction of mild hybrids to Audi’s model range is set to edge efficiency ever closer to the kind of economy figures enjoyed by TDI owners. But it doesn’t mean the death of the diesel engine, as the introduction of cutting edge technology can be paired to both TDI diesel and TFSI petrol engines. Audi says that within ten years, its entire model range will feature the technology. The key elements of the new system are an 11 Ah capacity lithium-ion battery pack and belt starter generator, with the latter replacing the current starter motor. Coasting becomes possible from around 9mph upwards, so that if the driver takes their foot off the accelerator, the car will coast along for a short time with the engine off, saving fuel. It’s possible to recuperate up to 5kW (7bhp), with the generator returning that power, reducing fuel usage and boosting economy as a result. And while this system can be integrated into current 12-volt systems, Audi is on the verge of announcing that it will put a new 48-volt system into production, with a capacity of harnessing 12kW (16bhp), that will allow coasting for up to 30 seconds, delivering even better efficiency compared to the 12-volt system. The company first gave a glimpse at the technology in the Prologue Concept car last year at the Los Angeles motor show. Other benefits of the introduction of a 48-volt electrical system includes the ability to have much smaller cable cross sections, reducing the weight of the wiring harness, and because it has four times the power, there’s opportunities to add additional innovative technology for the suspension and drivetrain. Further into the future, Audi’s engineers plan to convert the auxiliary systems, like pumps, superchargers for the engine, transmission and air conditioning system to 48 volts. Today these are driven hydraulically or by the engine, but in the future they will be powered by electricity and lighter and more compact. Audi will soon announce an electromechanical active roll stabilisation system, which features an electric motor and a three-stage planetary gearbox that separates the two halves of the stabiliser from each other. For relaxed and comfortable driving, the two halves are decoupled, resulting in cossetting ride comfort. For the sportier driver, the tubes are interconnected and twist against each other, delivering a tauter, more dynamic ride, and less roll when cornering. The front and rear stabilisers can also be adjusted independently allowing even greater degrees of fine tuning. The system is also capable of harnessing energy, and the motor can act as a generator, converting it to electrical energy. But Audi’s engineers are already looking at a second, more advanced project using the 48-volt setup, though it is still in the very early prototype stage. Being developed under the working title of eROT, an electromechanical rotary damper replaces today’s hydraulic item. The system isn’t too far apart from the active roll stabilisation arrangement in terms of basic principles, but a strong lever arm absorbs all of the forces that occur on a bumpy road, and via a series of gears, the force is transmitted into an electric motor, which then converts it to electricity. Recuperation is, on average, around 150 watts on an average road, with a freshly resurfaced road generating as little as 3 watts, while a badly maintained country lane may generate as much as 613 watts. Over a cross section of different roads, CO2 emissions savings could be as much as 3g/ km or four to five mpg.
  • VAUXHALL news.

    When the Astra range was unveiled, Vauxhall shouted from the rooftops that its most frugal 1.6-litre CDTi ecoFLEX model was capable of emitting just 82g/km of CO2. But a couple of months on and the figures have been revised, and the reality isn’t quite as favourable, with 88g/km the newly quoted figure for hatchback editions. This results in the fuel economy on the combined cycle amounts changing from 91.2mpg to 85.6mpg - a reduction of 5.6mpg. Customers that have ordered vehicles based on the more favourable figures will no doubt be disappointed and perhaps question whether this was a deliberate ploy to hit headlines. And the same issue affects the most powerful 1.6-litre CDTi Biturbo editions with 108g/km previously quoted, whereas in reality the actual figure is now 111g/km. This not only results in a fuel economy figure that is 1.6mpg lower, but it also means an extra Ј10 per year to purchase the vehicle excise duty. Despite the amendments, the prices of all Astra models remain the same as before.
  • CRF 1000L Africa Twin.

    Honda unveiled the celebrated CRF 1000L Africa Twin in Europe for the first time at EICMA. This adventure-tourer motorcycle is powered by a 998-cc parallel twin engine that draws heavily on Honda’s CRF 250 and 450 competition machines and uses the same four-valve Unicam head design. While the standard Africa Twin is available with a six-speed manual gearbox, there are two more versions to be had. The first features ABS and Honda Selectable Torque Control (HSTC), which controls the amount of torque going to the wheel and, in doing so, prevents or allows wheelspin. The last variant of the Africa Twin features Honda’s Dual Clutch Transmission (DCT) that was first seen on the VFR 1200F. Unlike on the sports tourer, however, on the Africa Twin, the DCT has also been programmed to function off-road. Unfortunately, it seems unlikely at the moment that the CRF 1000L Africa Twin will head to India anytime soon, but there’s no harm in hoping, is there?
