Note:

The first few shifts on a new vehicle

may be somewhat rough. This is a

normal phenomenon, and precision

shifts will develop within the initial

few hundred kilometers of running.

Mahindra has finally introduced the

automatic version of the new-gen

Scorpio. The Scorpio Automatic is

available in both 2WD and 4WD versions,

carrying a price tag of Rs 13.13 lakh and

Rs 14.32 lakh (ex-showroom, Mumbai),

respectively.

Mahindra used to offer the previous-gen

Scorpio with an automatic gearbox.

However, at the time of the launch of the new-gen Scorpio in 2014, the SUV was

only made available with a manual gearbox across all trim variants. Mahindra may

have taken its own sweet time to introduce an automatic gearbox in the new-gen

Scorpio, but then it comes with one major improvement.

Unlike the last-gen Scorpio, the new model incorporates a 6-speed automatic

gearbox as opposed to a 5-speed transmission in the previous model. This

gearbox is slightly more advanced and new-age than before since it also does duty

in the SsangYong Tivoli, which is only available in foreign markets as of now. For

the uninformed, SsangYong is an Korean automobile manufacturer that was

acquired by Mahindra

in 2011.

The powertrain is also

the same mHawk

engine that is available

with the manual

variants of the SUV. It

is a 2.2-litre,

turbocharged four-

cylinder diesel unit

developing 122PS of

maximum power at

4,000 rpm along with

280 Nm of peak-torque between 1,800 and 2,800 rpm.
