Just like the Maruti Suzuki Swift and Dzire, Tata Zest and Bolt also share the platform and most of the features. Interestingly, the diesel engine in all four these cars is the same Fiat sourced 1.3-litre Multijet. However, Zest gets it in two power options 75PS and 90PS. So, if we compare the performance Zest has an upper hand with its 90PS diesel engine. Zest's 1.2 Revotron petrol is also more powerful and Swift's and as it comes with three different power modes it has a further advantage. Both Zest and Bolt are also more feature rich than Maruti Twins. However, the Swifts get advantage at ride & handling and overall fit and finish. Maruti Suzuki's after sales service and unmatchable resale value also go in Swift twin's favour.
