The Suzuki Celerio (or Maruti Celerio as it’s marketed in India) is a cheap and cheerful point A to point B means of personal transportation. Sales were temporarily put on hold after someone discovered a brake failure during a controlled test in the UK, but the Suzuki Celerio is now back on its feet, boasting an all-new turbo diesel engine - a two-cylinder lump.
Available from 4.65 lakhs (€6,589 or $7,472 at current exchange rates), the India-spec Maruti Celerio with the first-ever Suzuki-developed turbo diesel engine is pretty good value. Until the Suzuki E08A 2-cylinder 0.8-liter turbo diesel came to be, the Japanese manufacturer was supplied or produced oil burners under license from other automakers.
So what is all the fuss surrounding this peppy two-banger motor? For starters, the Suzuki E08A diesel engine displaces a diminutive 793 cc, employs a DOHC architecture and it boasts 8 valves. The intercooled turbo diesel’s bore and stroke are 77 mm and 85.1 mm, respectively.
With a 15-to-1 compression ratio, the output is 35 kW (47 PS /47 HP) at 3,500 rpm and 125 Nm (92 lb-ft) at 2,000 rpm. It’s not enough to get your pants on fire, but the Suzuki Celerio city car is very light. The Japanese automaker says that the E08A engine has “realized weight-saving by adopting aluminum for the material of cylinder block and installing compact fuel distributor system.” The turbo is small as well.
By decreasing the compression ratio and installing a sufficiently large intercooler, “it has combined high torque in the low rpm range and fuel efficiency.” Yes yes, that’s nice and all, but what about the sound?
While the annoying diesel clutter can’t be helped, the vibrations of sub-3-cylinder engines has been addressed by Suzuki by optimizing the flywheel of the E08A diesel motor. Fuel economy? 27.62 kilometers per liter. That’s an astoundingly frugal 3.6 liters per 100 km, 65.3 US mpg or 78.4 UK mpg.
