On the Inside:
Unlike the exterior, the interior dons significant (very welcome) changes. As a relief, the speedometer cluster is back where it belongs, thanks to the Manza's dashboard being used. Let's face it, center-mounted meter consoles just don't work in passenger cars. The instrument cluster is a direct lift from the Manza parts bin, as are many other components. Two neat touches : The speedometer illumination dims itself when the headlamps are turned on, and the tachometer needle becomes progressively red as you approach the redline. However, speed readings aren't clearly visible due to the smaller fonts. The D90's entire cabin gets white lights.
The center mounted MID is basic, but easy to read. You can toggle between the distance to empty count, instantaneous fuel economy and average FE. I'd prefer the toggle button being placed within reach of the steering wheel; it's quite a distraction to operate the MID with the button placed on the instrument cluster. A big clock and outside temperature make up the other display data.

Average fuel economy:
Our test car (
ZX+ variant) was equipped with a double-DIN touchscreen TFT DVD head-unit. In a segment first, the head-unit has an inbuilt voice enabled GPS system. Maps can be updated as and when they are released. The GPS led us to
Sunny-da-dhaba via the shortest route on the old Pune-Mumbai route. Halfway through, I chose to take the expressway and it seamlessly recalculated the new route in swift time. The music volume automatically lowers when GPS instructions are given out.
As a sore point, the display is very bright, even at the lowest setting. Its glare lights up the cabin at night. We tried to enable night mode as well, albeit that didn't help. We suggest you enable the sleep feature to turn off the display (after an idle interval). On the flip side, the display is not clearly visible under direct sunlight. The response time of the touch panel has a noticeable delay too. Don't expect dual-core PC speeds on the display refresh, else you'll end up sorely disappointed.
The HU's main menu is inspired by tablet PC layouts. On the home screen, you can choose the feature you'd like to use. Come to think of it, the only buttons on the HU are a volume / power knob, navigation shortcut and disc eject. Everything else is controlled via the touchscreen interface. A disadvantage is that, touchscreen head-units aren't the easiest to operate while driving.
The head-unit is versatile and accepts USB, SD, Micro SD, Aux-in and DVDs as your file source. On the quality front, I would rate the 4 speakers and 2 tweeters as average. For the audiophiles among us, this isn't the setup you'd care for. For feature seekers and function lovers, it's just about at acceptable levels.
There's support for pairing up to 5 mobile phones via bluetooth. The steering mounted controls facilitate answering phone calls, volume, track seek and mute. Must say that the buttons are neatly integrated and made of good quality material.
Automatic Climate Control:
The ZX+ variant gets an automatic climate control unit. Tata has gone a step ahead and added a solar sensor on the dash to gauge the location of the sun and adjust cabin temperature accordingly. This, they claim, helps in setting just the right ambient air flow and temperature for passenger comfort. While this might be a thoughtful addition, we couldn't really make out much difference in cabin temperature while driving with sunlight on the windscreen, or when the sun was shining on the boot.
The ACC correctly maintains cabin temperature at night. We didn't have to fiddle around too much to get to a comfortable setting. The air-conditioner is an absolute chiller. It's noteworthy to mention that the air-conditioner doesn't drop engine power; the 1.3L diesel takes compressor load quite well.
The ACC offers three modes:
Normal: Manually set blower speeds and temperature using ultra cheap rotary knobs.
Auto: Completely automatic, based on ambient outside temperature and inputs from the solar sensor.
ECO: Maximises fuel economy at the cost of outright cooling. Lesser engagement of the compressor.
