It looks like the wait might soon be over for aspiring Tesla Roadster owners as the company has just announced that it has completed validation of the upgraded drivetrain 1.5. Tesla has so far delivered 27 cars to customers with the interim drivetrain and another 23 cars are in progress. According to Tesla SVP Darryl Siry, 11 more cars will have the interim drivetrains installed for initial delivery. From that point on, within the next 2-3 weeks, the company will start installing the new drivetrains – including the upgraded motor, power electronics and single speed gearbox. For production, veteran transmission manufacturer BorgWarner will build the gearboxes for Tesla. Over the last several months, Tesla has been testing cars with the same transmission design manufactured both by BorgWarner and in-house at Tesla but ultimately chose BorgWarner.
Now that the powertrain is ready, Tesla will ramp production starts from four cars per week to ten per week. By next March, Tesla hopes to be up to 40 cars per week. The upgrades mean the Roadster’s motor now goes from 211 to 280 lb-ft of torque, while the range also increases by ten percent to 244 miles. Over the coming months, the 38 cars that are delivered with interim powertrains will also be retrofitted with the new hardware. Sounds like it’s time for another Tesla Roadster drive.
