It runs on what?
Peugeot ready to unveil its latest iteration of the Hybrid Air de sign
A CAR that runs on air ? Peugeot is working on it. The French automaker revealed its Hybrid Air technology las t year and will sho wcase the 208 Hybrid 2L Demonstrator car at the P aris Motor Show next month. The latest iteration of the Hybrid Air de sign c omplements the g asolineair powertrain with weight and dragcutting measures to offer fuel economy in the range of 117 mpg (2 l/100 km), w hich is w ell abo ve the 81 mpg (2,9 l/100 km) it w as quoting las t y ear. PROTOTYPE MA TERIALS T O REMAIN Beginning with the 82 hp (61 kW) 1,2litre PureTech 208 fiveseater, Peugeot’s engineers reached into their materials catalog, swapping in car bon composite body panels and coil springs. They also reworked the thickne ss of the s tainless s teel on the exhaust system to provide a 20% weight saving, helping slice 220 lb (100 kg) compared to the production 208, do wn t o 1 896 lb (86 0 kg).
While exotic materials are sometimes dropped when a car moves from prototype to production, Peugeot says that its team looked specifically for “materials compatible with e xisting production facilities and a high manufacturing output”, suggesting a pr oduction v ersion c ould f eature the same c onstruction. AIR REFILL S IN 10 SEC ONDS The Hybrid Air powertrain combines the 1,2litre petrol engine with a c ompressedair dri ve.
Unlike las t y ear’s H ybrid Air c oncept, w hich used a longitudinall y mounted air t ank running down the c entre of the car , the 208 H ybrid 2L carries its compressed air t ank below the trunk, with a lowpressure expansion tank mounted near the rear axle. The compressed air works in c onjunction with a fr ontmounted hydraulic motor/ pump system to power the car and refill in about 10 seconds during deceleration or by way of compressed air de veloped b y the thr eecylinder engine. A be spoke epicyclic transmission balances output fr om the t wo po wer sour ces. 0,9 LITRE S MORE The car has a zero emissions Air mode for lowerspeed urban driving, Petrol mode for steady highway driving, and Combined mode for “transition phases in urban environments, such as s tanding starts and ac celeration”. As the demons trator model name indicates, this balance results in efficiency levels as high as 2 l/100 km, an impr ovement fr om las t y ear’s 2, 9 l/100 km figur e.
It is as yet unclear whether this promising hybrid technology is still on pace to launch within the ne xt t wo y ears. — Gizmag .com
