Suzuki Alto 660cc R-Series Engine! More advanced than K-Series?


The much awaited Suzuki Alto 2019 has finally been launched. You will soon see it hitting the roads and that too in huge numbers. Pak Suzuki has made a big deal about the technology used in this car and it’s all new R-series engine which is their most advanced engine to date. So what makes this new engine configuration special and is it a worthy upgrade over its predecessor the K-series engine. Let’s find out.

First produced back in 2011 and initially used in Suzuki MR-Wagon, the R engine from Suzuki is an inline-three engine which succeeds the older K6A engine seen in cars like Suzuki Wagon-R (Non-Japanese). This newer engine, known as the R06A, is made available as a naturally-aspirated as well as turbocharged configuration from Suzuki. The power output is a respectable 39hp for the naturally aspirated variant while the one with a turbocharger adds 10 more hp. The previous gen K-series engine was being used since 1994 and there are a couple of ways the newer R-series improve on it. First, the R06A features four valves per cylinder which mean 12 in total, dual overhead camshafts, with a bore and stroke of 64.0 and 68.2 mm (2.52 and 2.69 in) respectively. The naturally-aspirated versions of the R06A also features a variable valve timing (Dual-VVT) on both the intake and exhaust valves (the first Suzuki engine to do so which is why Pak Suzuki made a claim that its the most advanced engine in any of its cars), while the Turbo-charged variants get VVT on the intake valves.

If this technology sounds familiar to you then you are absolutely right. We have seen this technology in Toyota models for quite some time now. VVT is famously known for giving your car a turbo-charged like feeling while driving past 4000RPM where you specifically feel an instant burst of power. However, VVT is the process of adjusting the timing of a valve lift event and is often used to improve performance figures but more specifically fuel economy and reduced emissions to match EPA ratings. So it won’t be a surprise if the new ALTO from Suzuki Pakistan delivers excellent fuel mileage along with being faster more agile than its predecessor the Mehran.

Though this engine will be nothing new for Pakistan since most Japanese imported Suzuki cars made after 2012 utilize this engine including the Suzuki Hustler, MR-Wagon, Wagon-R, and Carry to name a few. All these cars are known for their excellent fuel average and a bag load of features. Combined with its small body, lightweight construction and a 39hp power-out the R-series is bound to make this car shine.

If you own the all-new Suzuki Alto, we are interested in your input especially in terms of its fuel efficiency. Kindly leave your comments in the section below.

I'm a crazy car guy. I want an aeroplane hangar full of cars. Is that too much to ask for?

    You forgot to mention diffrence in power delivery of the engine. It is 39hp for PK version while a JDM is 48 Manual and 51 for AGS as well as the CVT.

    Sir so you mean to say the engine power is same as Mehran? 😟

  • Fazal Wahab

    Yes.. but with a slightly smaller engine

    Shit -_-
    The only reason i was so excited about this car was its engine.

    Wikipedia notes its output = 54 & 64 hp, not 48 & 51!

    Don’t be so disappointed.
    Peak engine power in Mehran was 34 hp while the same engine in Bolan and Ravi outputs 37 hp and a different sound (and more noisy) due to different exhaust system and different cooling system philosophy.

    You can remain excited about the engine.
    The power band is what matters, not only the “peak output” value.

    Let me ask you this:
    What does the engine output at 1200 RPM (which is what you have when moving from stand-still)?
    What does it have at 2000-3000 RPM (cruising speed)?
    What does it give out at 4000 RPM (overtaking speed)?

    It is the entire experience that matters. Nobody ever uses their engine at 6500 RPM! That figure is useless! Give me the whole RPM vs power graph and let me bask!

    Flatter power band would make for a much nicer ride compared to a car which can never reach its peak-power RPM because at the low-end, engine power is not enough for the engine to even achieve its peak-power RPM.

    A 39 hp, DOHC, dual-VVT, 12-valve, 660cc, MPFI distributorless engine using lightweight synthetic oil will have entirely different power graph and will give far more driving pleasure, better acceleration, far more consistent performance, better aural experience compared to 34 hp, SOHC, 6-valve single-injector or carburetted engine (which has obsolete vacuum-advance based conventional breaker-point distributor) fitted in a car with cramped interior and poor ride quality!

    Fuel quality in Japan and Pakistan is different. Emissions standards are also different meaning the catalytic converter in JDM & PKDM may as well be different. Most probably the imported JDMs’ engines are already producing lesser power than what they were producing when those Altos were in Japan.

    It is high time we reduce our attention from cars and pay more attention to surrounding infrastructure e.g. fuel quality etc. While some articles outside the routine scope like how to avoid being looted at the petrol pump have been published, the more focused articles for advanced audience like fuel quality testing have never been published, and even no update on that MMT issue which should have been reduced to 0 mg/lit after that 30th April 2019 deadline.

    Dear All,
    I have been driving the new Alto for almost a month. The drive is very nice and it does not feel underpowered rather if you accelerate quickly it suddenly gives you much more power, thanks to it’s vvti engine.
    Mehran or even old model 1000cc Alto is nothing compared to this car.
