Interesting News
  • MERCEDES-BENZ news.

    Continual evolution of the latest S-Class sees CO2 emissions drop for the S 350 d versions, with the SE Line long wheelbase car now producing 141g/km and 52.3mpg, where previously it was rated at 148g/km and 50.4mpg. AMG Line versions see a reduction, too, with the standard wheelbase versions dropping down to 146g/km and 50.4mpg, where previously it was 154g/km and 47.9mpg, and the long wheelbase edition now emitting 148g/km and 50.4mpg, respectively, compared to 157g/km and 47.1mpg before.
  • VAUXHALL.

    When the Astra Sports Tourer was first announced, Vauxhall boasted efficiency of 99g/km for the 1.0i Turbo ecoFLEX editions and an even lower 96g/km for the Easytronic automated manual versions. But with homologation now complete, those figures have crept up by 1g/km with the official figures declared as 100 and 97g/km, respectively. The latter version sees a change in official fuel economy figures that are quoted, too, with 67.3mpg listed, as opposed to 68.9mpg before. These changes mean that for company car users, the manual gearbox version at 100g/km increases by one benefit-in-kind band to 18 per cent, compared to 17 per cent previously, while Easytronic versions stay the same as before. The prices are unchanged, too, with the Astra Sports Tourer Design 1.0i Turbo ecoFLEX priced at Ј17,285, rising to Ј17,985 for the better equipped Tech Line version. The load-lugging Astra Sports Tourer is set to arrive in UK showrooms in February.
  • BIG BIKE VS. SMALL BIKE.

    We see it quite often at the racetrack, especially in club races where classes are mixed: Rider on small bike passes rider on big bike in seemingly every corner, only to be passed back right away on the next straight. Even if the power difference is not that great between the two bikes, the contrast between corner speed and straightaway speed of the two bikes becomes magnified as each bike is ridden to maximize its advantages. The reality of the situation is that the outright maximum cornering speed between any two bikes is not that significantly different, provided both are on similar tires. If the tires are similar, both bikes should be capable of the same lateral acceleration (limited by the friction coefficient of the tires) and corner speed. Why do we see such a contrast in how the bikes are ridden? On an underpowered bike, the quickest way around the track is to maximize corner speed, in turn getting onto each straight with as much speed as possible. This is accomplished by completing the corner with as large an arc as possible, which converts lateral acceleration into maximum corner speed. For a typical single-radius corner, this means entering as wide as possible to maximize entry speed, turning in to the apex with little trail- braking, and keeping the bike at maximum lean with a constant radius until the very exit of the corner. In contrast, the quickest lap times on a more powerful bike are usually found by maximizing acceleration onto each straight and taking advantage of that power; this is achieved by sacrificing some corner speed to pick the bike up and apply the throttle earlier at the exit. For that same single-radius corner, this means a tighter entry, more trail-braking to a slightly later apex, with a tighter arc and less corner speed to get the bike up off the side of the tire as quickly as possible. As we found out in our displacement test last year where we compared the Yamaha YZF-R6, Suzuki GSX-R750, and Kawasaki ZX-10R, it’s not so much that the smaller bikes have a handling advantage over the bigger bikes but rather it’s how each bike is ridden to play to its strength or weakness in the power department. Using data from our AiM Solo GPS lap timer, we could see differences in line and cornering speeds between the three bikes, just as you would expect given the horsepower of each. While a few horsepower here or there might not seem like it should impact line choice signifi- cantly, in practice even a small difference can significantly change how a particular corner or series of corners is negotiated. And the contrast between a lightweight bike and a literbike can be astonishing: We’ve encountered certain corners where the entry line is several feet different on an SV650 than it is on a 1000, for an example. Finding the optimum line to match the power of your bike does require some experimentation. The wide radius and high corner speed that less powerful bikes require typically brings with it a higher risk of a high-side crash in the middle of the corner just as the throttle is opened, and the safer option is to start with the tighter entry and lower corner speed of the big-bike line and work from there, adding more corner speed and a wider entry with practice. If you are looking at sector times on data, don’t forget to factor in any time gained or lost on the succeeding straight, which may or may not offset time saved in the corner itself. Given the contrast in lines between different bikes, the key point to remember is that the optimum line for your bike may be very different from the bike in front of you, and it’s quite often a mistake to blindly follow another rider at the track. Even if you are riding the same model of bike, the power difference may be enough that you can take advantage of a different line to be quicker, and that line may work to a further advantage when it comes time to make a pass. When you ride at the track, what bike you are on will at least in part determine what lines you should be taking, and you should try different options with that in mind. And if you change bikes and move to a more or less powerful machine- or even make modifications to the same bike for more power-know that the lines you had been using for years might need to be altered appropriately.
