Disconnecting the Electric Power steering (EPS)
The bounciness in ride and the vague steering are the biggest grouse of driving the new Alto K10. Take the new Alto K10 out on the highway and hit triple digit speeds and one will understand how the flighty nature of the car makes you to hold the steering as firm as possible. Even a slight input would send the spinal nerves a jerk and a little more input could even throw the car off the road. One statement in the official review reads “This is the scariest car I have driven” and I have no objection over this statement. To be frank and long story short, the drive on the highway in the new Alto k10 is simply not confidence inspiring at all. Period.
I have been pondering over to overcome these issues from the start. There are various methods of addressing it like switching to better tyres, upgrading the suspension etc, but it all involves pumping in cash. But I wanted something that doesn’t consume my precious time & money. And it has to be something that doesn’t alter the OE fitment much.
There has been a long debate on the Electric vs. Hydraulic steerings with a good population supporting either one of it, since they both have an upper hand over the other. Hydraulic steering gives the feel of the surface it is being driven, but consumes power from the engine resulting in considerable loss of fuel efficiency. EPS on the other hand is good for city driving and does not suffer on the fuel efficiency part, but not as lively as the hydraulic steering.
Whatsoever, an EPS has never been the cup of tea for the enthusiast. The vagueness or the so called ‘play station effect’ takes a toll on the driving confidence. This is more pronounced in cars like the K10. But the question here is, do the light cars really need a power assistance to steer? What about a non-assisted steering or a steering that could be turned on or off, on demand?
For any electrical part in a car there should be a fuse or relay to save the device from over currents. If the fuse or the relay is removed the device is disconnected and it doesn’t work. So I thought of removing the power-steering fuse and give it a try. I wanted to feel the real feel of my steering on the Alto K10. So went ahead and googled for the fuse location and identified it. Checked if it could pose a serious issue if removed. Nothing serious. So I decided to pull the plug off the power steering. I removed the power steering 30 A fuse and voila! Here is what happened next.
I moved it out of my parking. The steering was hard, but not so hard that I could not steer it. The EPS has been put to sleep for a while. I hit the road and tried to make a ‘U’ turn. I couldn’t make it like I used to as I had got used to assisted steerings. Had to make multi point turns to make my usual ‘U’ turn that was just a flick of the steering wheel for me before. I feel the road surface. The steering didn’t feel twitchy now. My confidence is getting boosted to alarming levels. More sportiness and stiffness/firmness in the ride is very evident. I went on to drive for a while until I get used to my new steering feel. I’m just lost of words to explain my feel now. God bless Maruti for making light cars. The “light lady’s” car is now transformed to be the “man’s monster”. Icing on the sweet cake is, it costs nothing.
What I got:
• Improved handling. The cars sticks to the line and the road feel is simply confidence inspiring.
• Steering felt lot better. The feel of the surface where the car is being driven is simply amazing.
• The bounciness has drastically reduced. Definitely not a flat ride, but not bouncy either.
• Better cornering. The car again holds the line. The skinny tires are not so evident.
• The car feels sturdy and the weightless feeling is completely gone.
• Pothole filled roads don’t destabilize the car since the feedback of the EPS is absent. There was absolute composure when taking potholes & speed breakers.
• The AMT felt a lot better. Even with AC on the jerkiness was very negligible. I suspect the ubiquitous low speed jerkiness might be because of the voltage drop due to presence of other electrical equipment. I presume the disconnected power steering should have improved the AMT mechanism or might be placebo effect. (Have to validate this for some more time to confirm)
• Finally the car felt like a tank, even if its not built like one.
What’s gone:
• The effortless parking is gone.
• Do not attempt to squeeze the car into that gap in the other lane in bumper to bumper traffic.
• Zippy drive is substantially gone and no more wheel screeching rides on ghat sections.
My preference would be, power assisted steering within the city or in bumper to bumper traffic and in ghat sections. On the highway its simply going to be non-assisted for that confidence, road feel and sustain my speedo needle pointing east.
I would recommend others who have the K10 AMT to give it a try to really get the feel of its sportiness. Since it is only just removal of the fuse, it is completely reversible and does not do much harm. This can be tried in all cars with EPS provided the weight does not bother you in cars that are built heavy. To add, light cars are a blessing in disguise. I don’t recommend for non-AMT versions as the left limbs are already doing the hard work and I don’t want to add more load and make your lovely drive a workout. The revv-happy K-series engine, the AMT and an optional EPS makes this car a desirable ride.
