While the Proton Saga EV Green Propulsion Conceptstole the lime light in University Putra Malaysia for the “Proton Exora- The Making” seminar, the national car maker also took to theopportunity to showcase the Proton Exora Prestige Turbo Prototype.
It is basically the Proton Exora Prestige Concept which was firstpreviewed at the Exora’s official launch event, but now fitted with aprototype turbo powerplant.
The turbo engine based on the 1.6 liter CamPro powerplant was builtin-house, without the input of Lotus. Which means, the engine mostlyfeatures aftermarket parts to turn it from a normally aspirated motorto a turbocharged one. It’s useful to test the durability andreliability of a Campro block when force inducted.
The production turbocharged powerplant for the Exora is beingco-developed with Lotus, and sources reveal that powertrain engineerswill soon leave for the UK to intensify the development.
Notice the aftermarket boost meter and various other extra monitoring gauges
The powerplant featured in the Prestige Concept shown above is saidto produce up to 270 horsepower, and with a torque figure that is ratedat about 350Nm. (UPDATE: Now that I think about it,this quoted figure seems a little over the top. While no doubt it ispossible especially if you strengthen the engine enough, it is notpractical for production use so the production car will not likely betuned to such extents as there is a high possibility for lots of turbolag and the 4-speed Mitsubishi automatic transmission must bestruggling with the torque.)
A source revealed that the turbocharged Proton Exora MPV could mostprobably hit the market by between end 2010 to mid 2011. Honestly forme despite many customers eagerly waiting for a more powerful Exora,later is better as it means more time for testing, and a turbochargedproduction engine is something very new for Proton.
The production turbocharged variant will very likely offer less thanthe 270 hp and 350Nm performance figures mentioned above, but even ifit ends up producing anywhere in the region of 170 horses and 240Nm oftorque, that would be a big leap already as it would be equivalent to anormally aspirated 2.4 liter engine, but with peak torque coming in ata much lower RPM.
It wipe out one major issue that the current Exora has, which is alack of go. The 1.6 liter Campro CPS that is currently being offeredwith the Exora produces 125 horsepower and 150Nm of torque. Proton alsorevealed that the Exora Prestige Concept is being sold to selected VIPs that have placed orders for the extra-luxury variant.
