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.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
