I TDed the new Swift yesterday and had been waiting for this official review thread to post. It was a ZDi,having clocked 2070kms. I noted the following points.
-The engine noise has been damped a lot is barely audible outside when at idle(you may mistake it to be a petrol). It doesnot filter into the cabin untill past 3000 RPM. After 3000RPM though,the engine gets quite audible(wound up windows and AC couldn't damp it).
-Turbo lag is there till about 1700 RPM after which it starts gaining pace and beyond 2100 its a beast(more like a hungry lion pouncing).
-In heavy slow moving traffic,i kept to 2,3 and 4th gears and the car didn't shudder or ask for lower gear(i drive a petrol car and i was happy)
-Interiors are good but quality of plastic is not so good. The black panels of the dash board looked of different shades under sun,the centre area felt a tad rough.
-MID displayed a FE of 14.9 KMPL(i was flooring the throttle). Sales person says it is giving 18-19KMPL with AC in city.
-Acceleration is addictive. Once the turbo spools,the car just lurches forward,can be frightening in heavy traffic.(it reminded of the Bajaj Spirit/Safire with its 2/3 speed auto gear box-the scooter would jump when the gear shifted from 1st to 2nd

). Overall i didn't find the acceralation as linear as stated by many.
- Brakes lack the required bite,could have been better(mind you i was driving a ZDi).
-The suspension crashed in sharp potholes.
-ACC cooling is not effective. Today was a sunny day and the cabin didn't cool that effectively even though the temp was at 18C. The ACC display showed temp as 61C and outside temp as 97C. The test drive person said it had developed some error due to misuse by people(in just 2000kms???).
-Blower speed beyond 3 in ACC is very loud and disturbing.
-The rear seats were more spacious and rear leg room has increased. Sales person said it was partially due to the recess carved in the back of front seats.
-The car was totally rattle free till now.
-The PW switch panel was already having a worn out look,like the car was 5 years old

.
-Stock ICE was very good. It is available as an optional upgrade for LXi/LDi/VXi/VDi buyers,albeit for 18k INR.
-I am 6 ft and i didn't have any of the two issues as pointed out by GTO inthe opening post during my 45 mins TD.
A lot has said about the design and interiors,so i won't add anymore. It is for the same reason that i didn't click any pics.
We had booked a white Swift VDi two days only after which we were given a TD and i stuck to my decision after the test drive(ZDi is proving very expensive). The waiting period quoted is 4-5 months. But the sales person says we may be able to get in a 1-2 month as we will be buying directly without any finance.
PS-According to him,the booking for Dzire has been closed. Also he was trying to sell us the Ritz which is available immediately and has a few offers.
