Car manufacturers like to add mysterious letters and numbers to all our cars; 2LT, 300ZX, Z71, RS, SS, 350Z, IROCZ, and SR5. Why? Why are alphanumeric car names so popular? These models listed here are just a small sample of the many such car names. We won’t even get started on the alphanumeric motorcycle name. Either way, we’re here to find out where the legendary Toyota SR5 moniker comes from and what it means. Do you know what SR5 means?

What does SR5 mean?
Simply put, SR5 stands for “Sports Rally 5” or “Sports Runabout 5”, depending on who you ask. The “5” was originally meant to denote a 5-speed manual transmission.
According to Mechanic Ask, the designation was introduced to Toyota pickups in 1979 to appeal to “sport-truck buyers”—a group of buyers Toyota thought the fourth-generation Toyota Pickup 4×4 might appeal to. The 5-speed transmission was a fantastic upgrade at the time.
There’s a second, more detailed branding explanation that Mechanic Ask Posits is a bit more interesting. The SR5 badge preceded the Toyota pickup. So when the “S” stands for a car with sporty characteristics, it makes a little more sense. The “R” represents a “ray of light”, indicating a car capable of speed. The meaning of “R” doubles to include the Toyota engine code. And the “5” was just to designate the cooler 5-speed transmission.
What was the first Toyota to have the SR5 badge?

According to Mechanic Ask, the SR5 name, although we associate it with most pickup trucks, actually spans multiple vehicles. In fact, the second generation Toyota Corolla (1970-1978) received the Toyota name first. It was the 1973 model year that the SR5 trim Corolla first appeared.
What does the SR5 mean in Tacomas today?
Today, we still see this designation on Toyota’s sportiest (smallest) pickup truck, the Toyota Tacoma. The SR5 badge is also available on Tundras, 4Runners and Sequoias. However, it has a different meaning today compared to Toyota’s earlier pickups.
As my colleague, Dan Mayfield, writes, “In the Tacoma, the SR5 is the base trim, and it starts at $27,150. The SR is usually distinguished by its lack of decals.” The once-premium SR5 trim offered a 5-speed transmission as opposed to the common 4-speed, which now refers to one of the lower trims. In today’s vernacular, the SR5 gets things like leather upholstery, a more powerful engine option and a six-foot bed. Items like Bluetooth and heated it up and it wasn’t even a twinkle in the eye of an original Toyota pickup truck from the 1970s.
The SR5 has a long and winding history
Regardless of where you know the trim name from, most Toyota fans have some experience with an SR5. Whether you own an SR5 Tacoma today, a sporty little SR5 Corolla back in the day or, like Marty McFly and I, dream of owning a 1980s Toyota Pickup 4×4 SR5, this badge has meaning – and now you know it. key.
