TurboPETROL for Merc

Saw a report today that a 2-litre turbo PETROL engine is planned for the new A-Class.

Unusual to have a turbo petrol in a Merc. Will this start a trend

Well, maybe the author just meant the 'usual' Kompressor?

Correct.

I don't think so: Due to construction restrictions (sandwich concept) space for engines in the A-Class is very limited so a turbocharged engine is a way to have much power from a relatively small engine.

The data are:

142 kw = 193 PS at 4800 rpm Max torque 280 Newton metres from 1800 to 4850 rpm (yes, 4850, not 4800) Available from mid-2005 Displacement 2034 ccm (effectively) Six-speed manual trans as standard 4 cylinders 2 valves per cylinder Bore 83 mm Stroke 94 mm Sodium-cooled exhaust valves Turbocharger is a joint development of Mercedes and DaimlerChrysler Research Meets EU 4 emissions standards Exhaust manifold is air-gap-insulated and directly welded to the turbocharger housing Clutch assembly with dual-mass flywheel

Not enough info?

Ok, some more: ;-) Ratios

1st gear 4,21 2nd gear 2,54 3rd gear 1,71 4th gear 1,26 5th gear 1,18 6th gear 0,95 Reverse 5,02

Note short 6th gear which only is 0,95 as opposed to 0,81 with A 180 CDI and A 200 CDI.

Final drive is unclear to me, either 3,24 or 2,70

Thanks!!

Just remembered - there are petrol turbos in the Smart. Still, they remain exceptions

(Test-drove one the other day, by the way, deliberately choosing the smallest engine.)
