Why a sequential transmission is so much faster than a dual clutch?
Including the flywheel and clutch, the sequential weighs nearly 100 pounds less than the DSG, which is a huge amount for a race car. The sequential also has fewer gear shafts to spin-just two versus three for the dual-clutch.
Can I skip gears when shifting?
Engineering Explained tackled the common practice in its latest episode and the short answer is yes, it’s perfectly OK to skip gears when upshifting or downshifting. When skipping a gear with a manual transmission, it should be noted the revs will take slightly longer to drop from the high revs to the lower revs.
What kind of transmission does a MR2 Spyder have?
Toyota chose to install a unique transmission option in some 2001-05 MR2 Spyders. The SMT transmission is an automatically shifted manual transmission with a single clutch. It offered near-automatic convenience and clutchless operation for those not comfortable with a conventional manual transmission.
What is the downshift system on a Toyota MR2 Spyder?
Both controls initiate a sequence in which the throttle is closed, the clutch is disengaged, and the shift mechanism is activated. On downshifts—as in Ferrari’s $155,000 360 Modena F1—the system provides a blip of power to match engine and transmission speeds for seamless events.
What’s the 0 to 60 mph time on a Toyota MR2?
Although this isn’t a problem during normal or even sporty driving, the shifts seem agonizingly slow at the drag strip. Any one of our test drivers could stab the pedals and snap the lever through the gate in half the time. So the 0-to-60-mph time — at 8.2 seconds — is 1.4 seconds slower than the last MR2 we tested.
Is the Toyota MR2 a low tech roadster?
On the plus side, the MR2’s selector is as intuitive as any we’ve seen, readily understood by parking valets with minimal coaching, and fuel economy is identical to that of the low-tech manual. With or without the sequential manual transmission, the MR2 is a charming little two-seat, mid-engine roadster.
