Regen braking is still there. It's better than the original two speed they planned for, because the "1.5 drivetrain" actually means the whole drivetrain is upgraded. The motor has more power and torque and better cooling/efficiency after all their listed changes. By the percentage improvement numbers they are giving, it's 325hp vs 250hp in the original and 305lb-ft torque vs 210lb-ft. The transmission is also more efficient and durable due to switching to a much simpler one speed. This means even with one gear instead of two, this "1.5 drivetrain" will outperform the original two speed. The gearing is between the original two gears in the 2 speed version.
It's good news, looks like the drivetrain is coming along. Now they need to do all the durability testing (including a visit to death valley). Looks like now at least they are on schedule so car #41 seems to be the first car that will get this new drivetrain.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
so the 1.5 gearbox is like the one that they wanted at the begining but without regenerative breaking? or does it change the acceleration
