Even though
it comes from an agricultural background, the SZ 2600 DI engine
is the strength of the Scorpio. Employing a KKK turbocharger,
this turbodiesel was developed for Mahindra by famed Austrian
engine consultancy AVL from a previous tractor engine it had done
for the Mahindra Arjun. The large displacement plus the brilliantly
matched turbo makes for torquey power delivery which is a delight
and a boon for a vehicle of its girth and weight. On the flip
side are noise and high fuel consumption. |
Make no
mistake about it, the greatest attribute about the new Scorpio is
its powerplant which is the way forward for the rest of the industry.
And this is not difficult to comprehend. The four-cylinder direct
injection all-cast iron engine has cubic capacity on its side to begin
with: 2609cc (sporting all-square cylinder dimensions of 94x94mm).
This engine was earlier used in some of the Mahindra tractors and
because the block could afford a large displacement this was chosen
as the mill to be developed by AVL of Austria which designed the powerplant’s
internals, gave it an 18.8:1 compression ratio, added a KKK K04 turbocharger
(operating at 2.2 bar boost pressures) and gave it robustness to take
on tough operating conditions. This push-rod unit, no overhead camshaft
here even though some others might have suggested so, activates overhead
valves but as you will read further, this doesn’t impinge on
the performance delivered. Mahindra states that the engine develops
109bhp (at 3800rpm), making it the first Indian-built UV to have power
output in excess of the 100bhp mark. No less impressive is the 255.2Nm
of torque (made at 1800rpm). The Scorpio needed this sort of engine
performance given its bulk and weight (1895kg kerb weight) and while
we would have liked a bit more, generally the power and torque on
tap will be appreciated tremendously by all those who desire street
cred from their SUV. Mahindra has done a good job of packaging the
ancillaries under the bonnet. Given the fact that air con and power
steering were to be OE from day one, Mahindra thoughtfully adopted
a very large radiator which is a step in the right direction. On the
engine front there is much to applaud Mahindra for, especially on
the thought process behind its concept and development, considering
the fact that it can work itself better with turbocharging to meet
future emission legislation.
A hydraulic clutch is employed to effect the transfer of power via
the 5-speed manual gearbox which is essentially the Peugeot BA-10
unit standardised by Mahindra some years ago. Nothing wrong in the
choice of ‘box but Mahindra could have looked at getting the
shift actuation to be less clunky and smoother shifting than what
we have at the moment. Mahindra has worked on the BA-10 transmission
for the Scorpio application but it yet needs to go that extra mile
to make it just right for those C-segment carwallahs it is trying
to lure. I can’t resist adding that nothing else will do.
