If you want the most power from your engine, going with a manual transmission is most likely going to be your best bet. While some modern automatic transmissions, i.e. CVT transmissions, manumatics, and conventional 4 or 5-speed automatic transmissions allow for some excellent acceleration, there is still usually a substantial difference in 0-60 times between these types of automatics and a 5 or 6-speed manual transmission.- For example, an automatic equipped Dodge Neon has a reported 0–60 MPH time of approximately 10.5 seconds. The same Neon when equipped with a 5-speed manual has a reported 0 – 60 time of 8.1 seconds; a huge difference. While most cars do not have this large of a 0 – 60 MPH gap between auto and manual transmissions, 99% of the time you will receive noticeably better performance from a manual gearbox.
- Acceleration with manual transmission is usually superior for a number of reasons, most predominantly gear ratios and the availability of more precise shifting. To explain, if you own a car that receives 200 horsepower at 7,000 RPM, but your automatic transmission will up-shift under full throttle at only 6,000 RPM, you probably will never feel the full amount of power that your engine was made to offer. So, your engine may be stamped with a 200 horsepower rating, but because your car is equipped with an automatic that up-shifts too soon, you may be missing up to 20% of available power. On the other side, with most manual transmissions, you can usually take the engine revs to the red line or past it. This enables you to get the most power possible to the front, rear, or all four wheels under full throttle take-offs.
