Suzuki Chairman RC Bhargava has gone on record saying that sometime next year
the company will stop making diesel engines of capacity less than 1.5 litre.
Bye, bye diesel, we shall always miss your high torque capabilities. But thank
god for small mercies, as the company has introduced a new 1.5 litre diesel
engine that has been strapped on to its popular sedan, the Ciaz.
litre DDiS 225 diesel engine
Rs 11.37 lakh (ex showroom
premium sedan Ciaz has emerged as the best seller in its segment for the third
consecutive year. The Ciaz has sold over 2.56 lakh units cumulatively since its
launch in 2014. The Ciaz already has a 1.5 litre petrol engine which is doing
pretty well in the country. It’s also there in the new Ertiga. Now the Ciaz
will have a new 1.5-litre DDiS 225 diesel engine and it comes mated to a new
6-speed manual transmission.
all the interior and exterior features remain untouched, we shall only be
delving upon the performance of the Maruti Suzuki Ciaz with its new 1.5 litre
diesel engine. The new engine delivers a peak torque of 225Nm@1500-2500rpm and
maximum power of 94hp@4000rpm.
first thing I noticed missing in the new 1.5 litre diesel engine was the fact
that it does not have smart or mild hybrid technology feature that was there in
the 1.3 litre diesel engine mated to a 5-speed gearbox. The technology is handy
when it comes to idle start stop function which helps conserve fuel. But that’s
no big deal and no one who buys this car will miss this feature.
I get into explaining my drive experience, let me point out that this new
engine has an improved low end torque. In fact, when you step on the
accelerator you really do not realise the turbo kicking in and this in turn
generates good solid torque at the low-end which makes city driving simply
awesome. Those of us who are living and
driving in cities know that our driving exhilaration lasts from one traffic
light to another. It’s in such a drive
pattern that a low end torque is so fulfilling, offering instant bursts of
is this diesel engine noisy and irritably full of vibrations? Now, it’s here that
the Maruti Suzuki engineers need to be given a pat on their backs for ensuring
that the NVH levels are refined. NVH stands for noise, vibration and harshness
that people within the cabin of a car experience when they are on the move.
begin with, the car comes with a Dual Mass Flywheel
along with optimised compression ratio. All this has resulted in superior
NVH performance, which in turn has resulted in a comfortable driving experience.
And to add to that, the use of light-weight
aluminium casted cylinder head and block along with optimised engine
calibration has contributed to improved fuel efficiency.
I am going to just restrict my views on the performance, it’s important that I
explain the advantages of a dual mass flywheel. Even a layman out there should
sit back and understand this feature.
of you who have been driving cars for long know that apart from the various
mechanical problems that come your way, there is definitely one relating to
your clutch. This problem occurs at some stage of your driving. Since the
clutch pedal is depressed a zillion times to change gears, a time comes when
your clutch wears off. Now vehicles come with either a single mass flywheel or
dual mass flywheel. Many cars come with single mass flywheel. A dual mass
flywheel is basically two flywheels with springs in the middle to act as a
dampener. The springs help absorb engine vibration which in turn reduces wear
on the transmission and the rest of the drivetrain.
the other hand, a single mass flywheel gives you a direct contact between the
engine and clutch assembly. It is
obvious that a single mass flywheel cannot dampen engine vibration as well as a
double mass flywheel. So with a double mass flywheel in the a 1.5 litre diesel
engine Ciaz, the ride is a lot smoother and better.
only flip side I see to a double mass flywheel is that unlike the single mass
flywheel, the cost towards replacing a clutch and flywheel assembly is a lot
more. Here the entire assembly is a lot more complicated and has to be replaced
as a complete unit. So please be careful
when you depress the clutch while changing gears.
Suzuki has also talked about an optimum compression ratio. Without going into
details of a compression ratio, let me point out that an engine's compression
ratio is the ratio of the volume of gas in the cylinder when the piston is at
the top of its stroke (top dead centre, or TDC) to the volume of gas when the
piston's at the bottom of its stroke (bottom dead centre or BDC). It is the ratio
of compressed to uncompressed gas. To put it plainly, increasing the compression
ratio to an optimum level definitely improves fuel economy as the fuel in the
cylinder is burnt efficiently. And in a diesel engine where there are no spark
plugs involved, the fundamentals of compression ratio hold a lot of
getting back to the drive, I am truly impressed by the new diesel engine from
Maruti Suzuki and within the cabin, the NVH levels too are top notch.
for the 6-speed manual transmission, well it is a perfect mate to the 1.5 litre
engine. Gear shifting comes easy and light. It’s only when you get into
uncongested highways that you can actually shift to the sixth gear and let the
car maintain a 100km plus speed. Within city and on light traffic roads, gears
4 and 5 are ideal for a smooth ride. Since this new engine is mated to a new
six-speed manual transmission, unlike the five-speed that was available with
the earlier 1.3 litre diesel engine, the reverse gear is slotted near the first
gear. This too is a convenient feature.
Maruti Suzuki Ciaz with the new 1.5 litre diesel engine is quite a capable car
with superb acceleration and convenient low end torque. While it’s an ideal car
for city drive, it’s also a comfortable car for long drives, since it comes
with several convenient offerings, be it the spacious cabin, the comfortable
seats, the smart entertainment system, a cavernous boot, safety features, besides
a smart design. Now with a new 1.5 litre
diesel engine, one can definitely look forward to a hearty performance!
