Avid Motorbeam reader Harshad spotted the upcoming Chevrolet Beat Diesel at Nal Stop, Pune yesterday. An American was sitting on the front passenger seat and measuring some parameters on the computer. Maybe GM is fine tuning the mileage (expected to be around 25 kmpl) to beat the recently launched Tata Indica eV2 which is currently the most fuel efficiency car in India. The Beat Diesel’s 1.0 liter, 3-cylinder engine will be known as XSDE (eXtra Smart Diesel Engine) and will produce 57 bhp of power and 140Nm of torque at 1750 RPM.The diesel Beat will be manufactured at GM’s Talegaon plant and is scheduled for a June launch.
