Does anyone know if the SR engine has the same or less horsepower than the SR5 and higher trim levels? Toyota’s website does not list HP figures yet, but it shows that the SR, SR5, and PreRunner all have the same engine. Car and Driver’s blog mentions that only the SR will have a tuned-down 228hp version of the 2.4 I-Force engine. I have also heard a rumor that if you get the SR with a manual transmission, it has the full 278hp version of the 2.4 I-Force engine, but with an automatic transmission, it only has 228hp.
Howdy,pal,comprehend this, the SR engine occupies a middle ground. The naturally aspirated version is decent, and the turbocharged version is a strong performer with excellent potential for further tuning.
