Let's look at the spanking new introduction - a continuously variable transmission (CVT) mated to the 1.2L petrol. In one phrase, the Micra CVT is *butter smooth* to drive in the city. Ladies will love the ease and jerk-free experience. It feels simple like the gearless scooters - "start, twist throttle, ride".
This is the same CVT gearbox that the Sunny uses. The Micra is the first car with the latest generation CVT coupled to a small 1.2L petrol. Over the CVT generations (it is 10 years old already), Nissan has brought down frictional losses to minimise fuel consumption. The current generation uses far less transmission lubricant than the earlier ones, leading to 40% lower friction. The computed fuel efficiency increase is 15%. The effective transmission ratio is 7.3:1, a range broader than conventional ATs. Testing under ideal conditions, the Micra CVT delivered better mileage than the Micra MT (19.34 v/s 18.44 Kpl). Of course, this is because the CVT has a super tall top gear ratio that the MT cannot boast of. In your daily work <-> home driving style, the MT will be the more economical. One really wishes Nissan had mated the CVT to the 1.5L workhorse diesel. Perhaps, in the next refresh?
The Nissan CVT comes with 2 modes of operation - the mileage-optimized 'Normal' mode, and the comparatively free spirited 'Sports' mode. Shift between the two on the fly, via a small button you press with the left thumb. Sports mode, when engaged, is indicated on the dash. The shifter is a simple P-R-N-D stick with a single "L" position to keep the belt in the 'low gear' range (for steep inclines, declines etc.).
Driving feel in the Normal mode isn't meant for enthusiastic drivers. There is a slight if significant delay at the start, after which the car pulls away smoothly & sedately. It really doesn't matter if one mashes the pedal to the ground; the transmission ECU moderates the engine RPM and transmission ratio as the car picks up speed. Don't expect an immediate surge on 'kick down' either. In the city, the Micra CVT is a seamless shifter. The 1.2L petrol engine is acceptably refined when it isn’t pushed, and the CVT's shifts are absolutely jolt-free. In conventional ATs like the i10 & A-Star, you still feel the gearshifts, however smooth they are. Not so in the Micra CVT.
Light pressure maintained on the accelerator makes it a boon to drive in bumper-to-bumper traffic conditions. The steering is feather light and the engine has sufficient pep for urban commuting. CVTs usually deliver power in a linear manner & the Micra is no different. The Micra is easy to point in and out of traffic gaps, and parking is only made easier by its small footprint. As the car accelerates, one can hear the up-down modulation of the engine to keep it revving in the band of peak efficiency. Acceleration isn't brisk at all though. Remember, it's a 1.2L petrol mated to a CVT. The Micra petrol doesn't have punchy torque at low rpms and power delivery remains suited to a sedate driving style only.
The Sports mode is slightly more aggressive, albeit at the expense of fuel efficiency. The standing start is quicker and Sports mode keeps the engine at higher RPMs, before stepping up the ratio. Above 70 kph though, there isn't much to differentiate between Sports and Normal modes. Passing slow moving traffic is easy, but you'll need to carefully plan overtaking moves on fast highway vehicles (if at all, you manage to overtake them). No, the Micra is no road burner. CVTs respond best to soft accelerator input. Prod the Micra harder and you take the car out of its comfort zone. The Micra CVT feels like a timid kitten on the expressway. When you want "sudden-go", the rubber band effect becomes extremely prominent. You'll see the engine rpm rising, without any real increase in speed. The Micra CVT does take its own sweet time to gather momentum. Also, at higher rpms, the classic 3-cylinder thrum becomes audible. In fact, when being worked, it sounds identical to the humble M800 / Alto 800!
Again, the Micra CVT will suit those with a conservative driving style. It's at home within the city only...the intended playground for most automatic small cars. If you are looking for fun with an auto tranny, consider the Honda Brio 5-Speed AT or VW Polo DSG instead.
Nissan says that they have made some changes to the suspension set-up. The ride is compliant over most road conditions, and the handling is safe & predictable for a family hatchback. No, it's no corner carver. High-speed stability is average up to 120 kph, but nervous afterwards.
