India was the fourth largest motor vehicle/car manufacturer in the world in 2016¹. Indian auto manufacturers produced a record. CRDI is an intelligent way of controlling a diesel engine with use of modern computer systems. CRDI helps to improve the power, performance and reduce harmful. L petrol and a 1. L diesel. The petrol is a 1,1. V DOHC, all- aluminium engine which churns out 8. BHP (@ 6,0. 00 rpm) and 1. Nm torque (@ 3,5. Being a new age petrol, it belongs to the Revotron family, even though it doesn't have a turbo. The diesel is a 1,0. V DOHC common rail engine producing 6. BHP (@ 4,0. 00 rpm) and 1. Nm torque (@ 1,8. This motor uses an aluminium head with a cast iron block. The diesel belongs to the Revotorq family. Both of them are equipped with Multi- Drive. Owners get the option to choose between 2 driving modes - City and Eco. These are basically 2 preset engine maps. While City mode is set as default, Eco mode needs to be manually selected each time you start the car. To put things into perspective, consider the City mode as a regular driving mode. It's the Eco mode that is different. Eco mode dulls the drive by ~3. You can literally feel the sluggishness while accelerating. Obviously, this mode is tuned for fuel efficiency and is best left to sedate driving conditions. We didn't feel any drop in air- con performance between the 2 modes. Do note that the Bolt & Zest get a 3rd mode called 'Sport' for peppier performance. The Revotron 1. 2. L Petrol: Fire her up and you'll instantly realize this is no Kappa. Being a 3- cylinder unit, vibrations are prominent. Even at idle, with the temperature gauge settled down, you can feel vibrations on the seat, steering wheel, pedals and gear lever. The 3- cylinder engine is very lumpy and can get vocal too. Owing to the car's 1,0. BHP / ton & 1. Nm / ton respectively. That's on par with the Celerio. Still, when driving around in the city, the Zica doesn't feel particularly sprightly. On the other hand, it feels relaxed. The talking point is its driveability. You can easily potter around in a higher gear and there is no shuddering felt inside the cabin either. It has enough poke to carry you in town with few gear changes, albeit in a relaxed manner. You won't find the need to rev the Revotron hard. Overall, it's a fair point A- > B commuter, but is no scorcher. Like some other 3- cylinder engines, city driving can get jerky though, especially in stop & go traffic. You'll have to put in special effort to drive smoothly. One needs to carefully manage the accelerator & clutch to avoid jerks. This 1. 2. L is fairly rev- happy and doesn't beg you to upshift closer to the redline. As the revs climb, the engine definitely gets more vocal inside the cabin, yet it doesn't sound thrashy or strained. Even if you hit the rev limiter, the fuel doesn't cut off suddenly; it will just hold on to ~6,3. Outright performance is comparable to the Celerio. In terms of cruisability, 1. We found the car losing steam beyond the 1. Overtaking manoeuvres will require some planning and downshifting. Highway performance will be even more ordinary with passengers + luggage on- board. The engine is audible inside the cabin past 1,5. At mid- level rpms, a very throaty sound filters through - it's almost diesel- like! Between 2,3. 00 and 2,8. We reported this issue to Tata and hope that it was a car- specific problem. Like other 3- cylinder petrols, you'll easily notice the drivetrain clank sound when you press the throttle again, after lifting off. Must add, the exhaust crackles when you lift off, like the Mini Cooper S . The sound isn't very prominent, but a keen ear / BHPian will pick it up (especially on the outside). Even after two layers of insulation, wind noise from the A and B pillars creeps in above 8. Open the hood and you'll appreciate the fantastic job done by the engine mounts to minimize the petrol's mental vibrations! Tata claims to have added a bed plate on the lower part of the crank case for rigidity & lower NVH. You can literally see the engine dancing about violently, but vibrations felt on the other components are only a fraction of that. To keep the cost of ownership & maintenance low, this engine boasts of hydraulic lash adjusters (no periodic valve tuning), a chain- drive and an auto- tensioner at the front- end Accessory Drive (increases life of the entire system, reliable and minimizes frictional losses). The 1. 2. L Revotron uses variable valve timing (intake only): 8. BHP (@ 6,0. 00 rpm) and 1. Nm torque (@ 3,5. These engine mounts are the most hard- working part of the car, thanks to the violent engine vibrations: No under- body protection plate. The ground is easily visible: Petrol uses a Bosch ECU, while the diesel deploys a Delphi unit: Both, petrol & diesel engines get hydraulic lash adjusters. This means that the tappets are hydraulically controlled, to maintain the valve clearance automatically. You don't need to manually adjust the valve clearance over routine services. Petrol also gets an offset crankshaft i. Tata says this has been done to reduce NVH levels and stress on the engine: Even the petrol's bonnet gets an insulation sheet: Reflective firewall insulation: The washer pipe is neatly held in place by these clips: Struts are hidden away under a plastic cover: The Revotorq 1. L Diesel: This is the same engine that was showcased at the 2. Auto Expo in the Manza Hybrid (Tata Motors @ Auto Expo 2. Obviously, over the years, Tata has given it many updates and bumped up the output too. Its performance figures are similar to the 1. L Indica e. V2, despite having 1 cylinder less. Step into the diesel after the petrol and you'll be a little confused! Quite contrary to the petrol's characteristics, the diesel felt more refined and the overall engine sound was noticeably muted in comparison! Yes, there were vibrations felt across the cabin - steering, gear lever, pedals, seats etc. However, these aren't present to an extent of being a deal breaker. When idling, the diesel is definitely less lumpy than the petrol. The diesel is also a lot smoother off the line. It effortlessly picks up speed from a standstill and feels zippier. Tata has tuned the engine well. Because of the small turbo and short gear ratios, there is almost zero turbo lag. It doesn't complain while pottering around in a higher gear at a lower speed, neither does it beg you to downshift. The Revotorq is very driveable & owners will appreciate this in their daily commute to work. Boost is felt past ~2,1. Power continues till ~3,8. If you insist, the diesel will rev all the way to 4,8. The diesel has a narrower power- band than some others. Unlike the petrol, the Zica diesel doesn't feel as gutless beyond that speed. That said, it's no road burner either (far from it). Overtaking fast moving traffic can be tricky. Not only will you have to plan the manoeuvre, even once you're actually overtaking, the short third gear (max 1. This car will do good to keep up with highway traffic and nothing else - power is commuter- like. I must mention a scary incident - the mats of the diesel were a size bigger. In the middle of an overtaking manoeuvre, I pressed the clutch for an upshift, but the pedal never came back up!! The damn thing had gotten stuck at the top edge of the mat putting us in a risky situation! We have given feedback to Tata on this mat design issue. Diesel clatter is less, but it has that typical 3- cylinder thrum. Stand outside and you'll be able to hear the engine sound, but on the inside, the Zica is surprisingly silent. Tata claims to have used a sound deadening sump for superior noise insulation. That drivetrain jerk that we observed in the petrol was also missing here. Wind noise however was identical to the petrol. Between the two engines, we'd pick the diesel. It's more practical & likeable. The 1. 0. 5L diesel engine produces 6. BHP (@ 4,0. 00 rpm) and 1. Nm (@ 1,8. 00- 3,0. Diesel gets an intercooler: Part of the new 'Revotorq' family of engines: The pressure on these mounts is a lot lesser than its petrol counterparts: Smaller turbo = good driveability and better low end performance. Turbo is from Honeywell: Diesel engine is belt driven, whereas the petrol is chain driven. Diesel gets balancer shafts for reducing the typical 3- cylinder vibrations: Its sump is made of sound deadening material to further reduce NVH. Like a sandwich material with an insulating sheet in between the inner & outer metal layers: No cover underneath. Floor is visible through the engine compartment: The petrol uses an Exide battery vs the diesel which has a Tata Green unit: Under bonnet insulation: The Zica has a ground clearance of 1. Gearbox, Clutch, Ride, Handling, Steering & Braking: Both engines use the same TA6. Indica e. V2), albeit the diesel's clutch appears to be different to handle the additional torque. The 5- speed manual gearbox's throws aren't long and the shifter's operation is decent. At times, it feels almost as slick as the Celerio's, but requires more effort to slot in compared to my Grand i. There is a tendency to mis- shift between 2nd & 3rd though and the gearbox isn't sure- slotting. Still, for a budget hatchback, it does the job just fine. The clutch is light and has a short travel range. Vid. 66. 39 particularly complained about the petrol's clutch which felt almost lifeless and didn't communicate shift points to the driver. The diesel's clutch, on the other hand, fared better in this area. The light clutch is a boon in bumper- to- bumper traffic conditions. There's even a dead pedal to rest your foot. Although it is placed a tad too high, we appreciate the fact that Tata has included this feature in here. Tata cars are known for their absorbent ride quality and the Zica is no different. It glides over broken roads and dismisses smaller potholes with a muted thud. The larger ones do filter in, yet the impact is adequately absorbed and the car doesn't toss you around like some other hatchbacks would. The suspension does its work silently too, without complaining. Must mention, there is nearly zero vertical movement after hitting a rough patch. Mid- corner bumps don't unsettle the car's composure and the rear end is well- behaved.
