The tension must be mounting at this point. Driventowrite is nearing the summit of the European motoring pantheon.
The thin air makes every upward centimetre a struggle against gravity. The cold gnaws into the core of your bones. To put it another way, the competition is fierce as more and more cars struggle to be near the epicentre of the best European motoring has offered. So many vehicles and only one can Continue reading “Great European Cars: Number 3”
Japanese automotive engineering went into warp-drive mode in the middle 1980s. The Nissan CUE-X of 1985 remains an impressive tour de force of the purest styling and technical experimentation.
Starting under the skin of this elegant and minimalistic design, we find electronic air suspension which controlled the spring rates, ride height and attitude. The damping could be altered as well making this a car which had the potential to fill a brief written by Citroen. Going further than Citroen did with their 1988 XM, the Cue-X also boasted four-wheel steering* The description of how it works is very similar to that of the XM: sensors sent signals to the vehicle’s central processor. The data described vehicle height, road speed, steering input, braking forces, throttle position and gear position. Continue reading “Theme: Japan – 1985 Nissan CUE-X”
Suspension systems are inherently reactive. One approach to managing the response of the body to road surface changes is adaptive ride suspension. Is it really any different from passive systems?
In both passive and active systems, the road surface’s variations are the main input to the body and suspension system. Passive systems are designed to build in to the suspension the capacity to absorb energy so that the body movement is controlled and tyre contact to the road surface is maximized. Active suspensions involve the use of actuators to change the height of the body at each corner of the car. This additional mechanism requires the use of variable-rate shock absorbers and dampers. The active ride system needs sensors to Continue reading “Theme: Suspension – Not As Good As It Sounds But Still An Improvement”
I spotted this on the Suzuki stand at Geneva. It’s the rear axle of the Vitara, the Hungarian-built Poor Girl’s Evoque.
At first I thought that it was a De Dion axle, on closer examination it turns out to be a torsion beam with driven rear wheels. Possibly other manufacturers have done this before, but it’s the first I’ve encountered. I’d have expected to find a live axle, or a multi-link or double wishbone fully independent system.
