New Supercar Technology Does Away With Windshields

The Wall Street Journal reports on a new technology being developed by McLaren Technology Centre for its "Elva," a multi-million dollar, 804-horsepower two-seat roadster. It doesn't have a windshield...In place of a windscreen, Elva will debut a technology called Active Air Management System (AAMS). When engaged, it generates two air flows streaming over the cockpit: One glances off the low, curvaceous wind deflector rising out of the front bodywork, with an energy proportional to vehicle speed. The other airflow is scooped up in a low-mounted grille intake and turned 135 degrees. Now ducted up and slightly forward, this high pressure flow intercepts the deflected airflow, bending the combined flows over the cockpit. Meanwhile, streaming air clinging to the hood wants to be drawn down, below face level, following the Elva's curving scuttle and dash. And so the Elva's historically unique, eye-of-the-hurricane gestalt: Driver and passenger motoring at highway speeds, talking at normal volume, as warm or as cool as desired and, looking out, seeing nothing... but scenery. No helmet limiting their peripheral vision as if looking through a well-padded porthole, stifling breath and sense of smell. And no heavy, roof-supporting "A" pillars either, which clumsily bracket existence in almost all modern cars. The Elva is the motoring equivalent of a horizonless pool. Under the right conditions the Elva's system can billow precipitation out of the way, over the car, so the occupants stay dry. Heading up the mountain to Gstaad? With the AAMS active, falling snow will swirl past but never settle... What about bugs? I asked. Will they be deflected too? "It depends on the mass of the bug," said Andrew Kay, Elva project chief engineer, being completely serious. What about stones thrown up by trucks? Overtalk...inaudible... In any event, McLaren expects all occupants will be wearing helmets on piste and will only engage the AAMS bareheaded at moderate speeds... At 60 mph, the wind was so still I could have lit a cigarette.
