The Z12E 1.2-litre engine under the hood is shared with the fourth-generation Swift and Baleno, and is a step forward in fuel efficiency from the older K12N unit it replaces. 

Producing 82 bhp and 112 Nm, the outputs are modest but appropriate for a car that weighs under a ton in petrol form. The three-cylinder configuration is inherently less smooth than a four-cylinder unit, and at idle and under moderate loads a low-frequency vibration is present through the cabin. It is not intrusive to an irritating point, but is a difference that buyers stepping from older four-cylinder sedans will notice.

In city driving, the engine is relaxed and easy to manage. It pulls cleanly from low revs, does not require frequent gear changes in traffic, and the light power steering makes manoeuvring in tight spaces straightforward. 

The 5-speed manual is well-matched to the engine's character, with light throws and a clutch that does not tire the left foot over long periods in traffic. The 5-speed AMT is the more popular choice for urban buyers and manages the engine smoothly at steady speeds. Its characteristic occasional jerkiness during the transition between first and second gear in stop-and-go conditions is an inherent limitation of the AMT technology rather than a specific Dzire complaint, and it is more pronounced on the highway than in the city.

The CNG variants, also paired to a 5-speed manual and an AMT, produce 69 bhp and 102 Nm (in CNG mode). This is a noticeable power redution on hills and during overtaking manoeuvres, but largely irrelevant in typical city use. 

On highways and open roads, the Dzire's limitations become more apparent and you start to miss the older K12. With a full load of four or five adults, the engine feels pressed when overtaking at speed, and the 5-speed gearbox's ratios mean it runs at noticeably higher revs for a given highway speed. Sustained cruising at 100 km/h is comfortable but the cabin sound at that speed is louder than the Honda Amaze and Hyundai Aura, both of which get 4-cylinder engines.

The suspension, shared in spirit with the Swift's setup, is tuned well for Indian conditions. 

Low-speed bump absorption is impressive, making the Dzire genuinely composed over the broken surfaces and sharp speed breakers. Body roll in faster cornering is present but never unsettling, and high-speed stability inspires confidence.

The Dzire's ARAI figures of 24.79 km/l (manual) and 25.71 km/l (AMT) are among the best for any naturally aspirated petrol sedan in India. The AMT's slightly higher figure reflects its optimised shift points rather than any mechanical efficiency advantage. 

Real-world petrol returns of 15 to 20 km/l represent a wide band because the Dzire's efficiency is heavily sensitive to driving style. Smooth, disciplined city driving can approach the upper end, while aggressive driving or stop-and-go traffic conditions can drop it to the lower end. On open highway stretches at moderate speeds, figures above 20 km/l are achievable.

The CNG efficiency of 33.73 km/kg is exceptional and the primary reason fleet operators and high-mileage private buyers choose the CNG Dzire in large numbers. The CNG tank capacity is 55 litres water equivalent.

The Dzire's cabin is the most meaningfully differentiated from the Swift's that any Dzire generation has produced. 

Where older models were openly described as Swifts with a boot, the new car uses a dual-tone black and beige interior theme with chrome accents that creates a more sedan-appropriate atmosphere. The dashboard layout carries over from the new Swift but the beige colour treatment lightens the cabin noticeably and makes it feel more spacious than its dimensions suggest.

The front seats are well-cushioned for daily use, with good back support for the class. The tilt-adjustable steering column is standard across all variants, and the leather-wrapped steering wheel and gear lever add a quality touch. 

The 9-inch floating touchscreen in the ZXi and ZXi+ is positioned well and responds cleanly. Wireless Android Auto and Apple CarPlay function reliably and are the primary interface for most owners. The 7-inch unit in the VXi is smaller but functionally similar in its wireless connectivity support.

The rear seat is the Dzire's most important selling point for family buyers, and it delivers. 

The 2450 mm wheelbase gives it legroom that compares well with most compact sedans, and the rear bench is wide enough for three adults with reasonable shoulder room. The backrest angle is comfortable, and the standard-fit rear armrest with cup holders and rear AC vents are present across all variants except the base LXi. 

Headroom is adequate for passengers up to around 5 feet 10 inches. The sloping roofline does limit headroom for taller occupants.

The sunroof, exclusive to the ZXi+, is a single-pane unit of modest size, and can also be operated via the infotainment touchscreen, which is a convenient touch.

The 360-degree camera in the ZXi+, also a segment first, offers a 3D composite view with dynamic rear parking lines. Image quality is above the basic rear-camera standard the segment was accustomed to before this generation.

The boot at 382 litres is decent but is the smallest in its class, as its direct rivals offer 400-420 litres. Regardless, the Dzire's boot is still good enough to fit full-size suitcases comfortably. 

However, the Dzire gets a fixed rear bench with no 60-40 split or full folding options, so large, bulky items can be a challenge to load into the car.

For the first time in the Dzire's history, it looks genuinely distinct from the Swift it is based on. 

The front fascia, with its wide horizontal grille featuring multiple slats and a large central Suzuki logo, bears no visual resemblance to the Swift's face. Crystal Vision LED headlamps with integrated DRLs feature from the ZXi variant upward, while the LXi and VXi use projector halogen headlamps. 

The side profile reads as a proper compact sedan, with a chrome window surround on ZXi and above, a gently sloping roofline, a pronounced shoulder line, and a clean overall form. 

Dual-tone 15-inch diamond-cut alloys on the ZXi+ are the most visually polished configuration, while ZXi variants get simpler black alloys. The LXi and VXi get 14-inch steel wheels.

The bootlid spoiler, present across all variants, gives the rear a slightly sportier appearance than the restrained overall design suggests. LED tail lamps are also standard on all variants.

Ground clearance at 163 mm is the lowest in the compact sedan segment and requires some care on very steep speed breakers, rough rural roads, and flooded urban streets. 

The fourth-generation Dzire's safety package represents a fundamental step up from its predecessors. 

Maruti's decision to standardise six airbags, ESC, hill hold assist, and ISOFIX across all variants is one of the most significant safety commitments at this price point in the compact sedan segment. No variant is available without these features.

The five-star Global NCAP rating (4 stars for Child Occupant Protection), earned in 2024, validates the Heartect platform's structural integrity. This was Maruti's first five-star GNCAP rating across any model, reflecting the structural improvements that the latest generation of this platform delivers. The rating used the standard test protocol including frontal offset and side impact assessments. 

The Dzire also went on to achieve 5 stars in the Bharat NCAP crash tests, for both adult and child occupant protection. 

The ZXi+ adds a 360-degree camera, a blind-spot monitor, and TPMS to the standard safety equipment. There is no ADAS on any variant, which is a gap that the Honda Amaze addresses with its Level 2 Honda Sensing suite.

The Honda Amaze is the Dzire's most well-matched rival, competing at a broadly similar price range with a comparable naturally aspirated petrol engine. It offers a stronger and more refined  1.2-litre 4-cylinder i-VTEC petrol engine producing 89 bhp, a smoother CVT automatic, Honda Sensing Level 2 ADAS on top variants, and a larger 420 litre boot. 

The Dzire counters with a five-star NCAP rating to the Amaze's unrated current generation, a sunroof and 360-degree camera at the top trim, stronger fuel efficiency figures, and Maruti's wider service network. 

The Hyundai Aura is the most popular alternative in the segment after the Dzire. 

Like the Amaze, it also holds a refinement advantage with a 1.2-litre 4-cylinder naturally aspirated petrol engine producing 82 bhp, with manual and AMT options, and a CNG variant. Its boot at 402 litres is also larger than the Dzire's 382 litres. 

The Dzire leads with a cleaner design, solid crash safety rating, AMT convenience with the CNG, better fuel efficiency and Maruti's wider service network. 

Tata's Tigor occupies the lower-price end of this segment and competes primarily on value, with a four-star Global NCAP rating (under older testing protocols).

Its 1.2-litre 3-cylinder naturally aspirated petrol produces 85 bhp, and gets a CNG option with an AMT gearbox. Interior features across most trims is below the Dzire, and the cabin quality is not as refined either. Boot space at 419 litres edges past the Dzire. 

The Dzire, barring its boot space, does everything else better than the Tigor.

The Maruti Suzuki Swift shares the Dzire's platform, engine, and feature DNA. 

For buyers who need a compact, city-friendly hatchback over a sedan, the Swift is the natural alternative within the same ownership ecosystem, with the same service network and running cost advantages. 

The Dzire's additional boot space, rear seat space, and sedan character differentiate it clearly for buyers who need the extra practicality.

The Maruti Suzuki Dzire is the most well-rounded version of the nameplate in its 16-year history, and it makes a compelling case that is difficult to dismiss regardless of the criteria applied. 

It is the safest compact sedan in India right now, with a five-star Global NCAP rating and strong standard safety features. Its fuel efficiency, at 24.79 km/l for the petrol manual and 33.73 km/kg for the CNG, is among the best for any sedan in India. The sunroof and 360-degree camera, both segment firsts, give it a premium credential no rival currently matches in the compact sedan space, and the CNG AMT combination fills the last significant gap in what was already the most flexible powertrain lineup in the segment.

It has its fair share of weaknesses. The three-cylinder engine, while refined by its own generation's standards, is audibly less smooth than a four-cylinder unit and feels pressed with a full load on highways, the AMT's occasional jerkiness will bother buyers who have driven smoother automatics, the 163 mm ground clearance demands care on rough roads and steep speed breakers, and the 382-litre boot is smaller than rivals by a fir margin.

The Dzire has always been a solid compact sedan that people can rarely go wrong with, and in its fourth generation, it is one of the better picks in its segment.
