From being a fuel efficiency champion, Maruti Suzuki has lost much of its lead when it comes to the mileage stakes in recent years as the growing competition has outperformed India’s largest automaker when it comes to building the most fuel efficient cars. For the record, the top ten most fuel efficient cars in India list doesn’t feature a single Maruti Suzuki. All that could change next year as Maruti Suzuki is said to be readying up a diesel powered version of the Celerio.
The Celerio Diesel could be launched next year and is touted to deliver a fuel efficiency figure of 30 Kmpl, a figure which will make the Celerio the most fuel efficient car in India. The diesel powered Celerio has been spotted testing on Indian roads on numerous occasions over the past few months.
The Celerio Diesel is expected to use a twin cylinder turbo diesel engine that displaces 792 cc. This engine will also be used on the Maruti Y9T mini pick up truck, which is also lined up for a 2015 launch. The video grabs showing the Celerio Diesel in action show prominent diesel clatter and an exhaust note similar to that of the Tata Ace pick up truck.
In order to make the Celerio Diesel acceptable to the masses, the noise, vibration and harshness (NVH) levels of the twin cylinder turbo diesel engine will have to be heavily damped. The Tata Nano is one car that comes with a twin cylinder petrol engine and the typical thrum associated with such motors. The higher NVH levels of the Nano is said to be a major reason for car buyers to reject the vehicle.
If the 792 cc-twin cylinder diesel engine indeed makes it to the Celerio’s engine bay, it will be the smallest such motor on offer in an Indian car. The smallest turbo diesel engine currently offered on a car sold in India is the 936 cc, triple cylinder motor of the Chevrolet Beat hatchback. If car buyers accept the twin cylinder diesel motor on the Celerio Diesel, expect more small cars from Maruti Suzuki to feature this very engine.
