Hyundai Verna

The most beautiful sedan in its segment, Hyundai Verna has maintained its unrivalled aesthetics with timely cosmetic changes with its facelifts. Ever since its launch, Hyundai Verna has been a parallel to the Honda City, and remained its immediate and strongest competitor. Doubtlessly, the Hyundai Verna is more than just its looks. A 2600mm of wheelbase provides an amply spacious cabin and with the help of a lengthy feature list, offers an immensely pleasant ambience for passengers. Moreover, the 480L of boot space is a nice add-on for family-oriented convenience.

The premium 5-seater sedan offers you a uniquely rich ride comfort with its well-contoured soothing upholstery for the most comfortable passenger experience for 5 adults. Moreover, if you prefer being in the driver’s seat, the agile transmission, the supple drivability, and very convenient steering give you the desired driving experience. Hyundai has equipped the Verna with a 1.5L petrol engine, a 1.5L diesel engine, and a 1L turbocharged petrol engine, a major advantage over the Honda City. A 6-speed manual transmission comes with both petrol and diesel engines. Moreover, the diesel engine gets a 6-speed automatic and the petrol engine offers you a CVT automatic while the turbocharged petrol engine comes with a sole 7-Speed DCT.

Maruti Suzuki Vitara Brezza

In the rivalry among the 5-seater compact SUVs, Vitara Brezza has been a strong performer for Maruti Suzuki. While competing with competitive SUVs like the Tata Nexon & FORD ECOsport Maruti Suzuki Vitara Brezza has always been among the top-sellers. With some cosmetic upgrades in 2020, the compact SUV retains its boxy silhouette and upright stance which adds to the visibility of passengers as well as the driver. A key contributor to its success is its spacious and feature-loaded cabin which is one of the most practical ones in the segment and ideal for five adults. A 328L of boot space further increases the practicality, especially for family trips. Moreover, Maruti Suzuki brandishes the 4-Star rating that Vitara Brezza earned in the G-NCAP safety test. The overall package of Vitara Brezza is well-suited for India’s urban and rural roads.

A refined and responsive powertrain that delivers a hassle-free ride with a lucrative mileage of 17-19 km/l, is a unique perk loved by every Vitara Brezza owner. The suspension is soft enough and smothers the bumps well. Maruti Suzuki offers Vitara Brezza with a 1.5L petrol engine which comes coupled with either a 5-Speed manual or 4-Speed automatic transmission.

The fact that 8,400 units of Tata Punch were sold within 10 days after launch is indicative of the immediate success Tata’s new mid-sized hatchback has acquired. Wearing the honour of 5-star global NCAP rating, Tata Punch indeed packs a punch with its muscular style and refined performance. Tata has equipped Punch with a 1.2L petrol engine which comes coupled with 5-Speed manual or automated manual transmission.

The smart pricing of Kia Carens is the major contributor to its massive success. With the base and mid variants, the Kia Carens rivals Maruti Suzuki Ertiga and Mahindra Marazzo, and its top variant takes on the likes of Hyundai Alcazar and Toyota Innova. With Kia Carens, Kia has successfully managed to make a phenomenal balance between budget and premium.

The prowess of Kia to make a family-oriented car a fun-to-drive car seen with its powertrain options. Among the three engine options on offer, the 1.4L turbocharged engine draws the attention of most driving enthusiasts. Moreover, the availability of paddle shifters, DCT automatic, and sports mode bring immense driving thrill. It’s worth noting, Mahindra Marazzo comes with a diesel engine, and Ertiga is offered with a 1.5L naturally aspirated petrol engine. These cars compete against the base and mid-variants of the Carens.

I think the most suitable cars for Mr. D.S. Pughazhyendhii is  Tata Nexon and Kia Carens they both have approximately same features as sizes, space , safety features ,mileage and some other properties but some extra additional features in the Kia Carens  and Pughazhyendhii is fond of big cars. 
Same goes for the Hyundai Verna the shape or design of the car is different mens sedan type only and small in shape and other one have the crossover / Mix type design and the more ground clerence then the  Hyundai Verna.
