According to the '2007 Four-Wheeler Total Customer Satisfaction' study released on Monday by leading market research firm TNS, the new models launches from the General Motors, Mahindra Renault and Maruti have been able to delight their customers.

"The growth curve of the Indian automotive market has been quite remarkable. Manufacturers have been able to read their customer expectations accurately and have responded with products, which have been in tune with the evolving needs," TNS Automotive's senior vice president Pradeep Saxena said.

"The evidence of this fact can be seen from the high level of satisfaction of the new customers of Chevrolet Aveo U-VA, Mahindra Renault Logan and Maruti Swift Diesel. These customers reposed their trust in the manufacturers and bought newly launched models and the manufacturers did not disappoint," he added.

Other models that ranked top in their respective segments included, Maruti Alto, Hyundai Santro, Honda City, Toyota Innova, Mahindra Scorpio, Hinda CRV, Skoda Ocatvia and Honda Accord.

"Some traditionally strong models continue to delight their customers. Maruti Alto finds extremely high satisfaction levels across all product and customer service areas. The Hyundai Santro and Accent are able to do much the same and this indeed speaks highly of how these manufacturers have been able to manage these brands through a 360 degree approach encompassing product quality, after sales service and brand image," TNS said.

The models ranking highest in their respective segments for total customer satisfaction were: Maruti Alto in 'Entry Compact', Hyundai Santro in 'Premium Compact', Chevrolet Aveo U-VA in 'Upper Premium Compact' and Maruti Swift Diesel in 'Small Car  Diesel.'

Other segment toppers were: Hyundai Accent Petrol in 'Entry Midsize,' Honda City in 'Mid-size,' Skoda Octavia in 'Premium Midsize', Mahindra Renault Logan Diesel in 'Midsize Car  Diesel,' Honda Accord in 'Entry Luxury,' Toyota Innova & Mahindra Scorpio (tied) in 'SUV/ MPV' and Honda CRV in 'Premium SUV.'

TNS said the TCS [Get Quote] survey, conducted by its specialist automotive division TNS Automotive, is the largest syndicated automotive study in India and represents responses of over 7,600 new car buyers, covering over 60 models.

The evaluation was done on parameters like sales satisfaction, product quality, vehicle performance and design, after sales service, brand image, and cost-of-ownership. The study was conducted from July through November across 28 cities.
