Tata rolled out dual-cylinder technology for its CNG cars last year with the Altroz and Punch CNG. The Tiago and Tigor - the brand’s first CNG cars launched in 2022, were also updated with the tech in the same year. Compared to conventional CNG set-ups comprising a single massive 60-litre tank in the boot, Tata’s system employs two smaller 30-litre cylinders sitting under the boot floor thus freeing up useable space within the boot.
