Video and Dyno Plots

Plot #1 - 2013 Accord V6 EX-L 6MT Coupe

Notes: Yep, that's nearly 260hp to the wheels and more than 235lb-ft, and this engine isn't even close to being broken in. These are pretty impressive figures from a fairly pedestrian SOHC 3.5L V6. It will be interesting to see what the RLX's "310hp" version of this engine pumps out on the dyno.

Plot #2 - 2013 Accord V6 EX-L 6MT Coupe vs 2009 Accord V6 EX-L 6MT Coupe

Notes: These dyno runs were performed at the same dyno facility but several years apart, so there could be discrepancies there. Also, the '09 Accord was tested during much warmer conditions, but the dyno software corrects for that difference using SAE conversion factors (in this case, the '09 Accord's results were corrected upwards by a factor of 5%. There is zero correction applied to the 2013 Accord's results as conditions were close enough to the SAE's base conditions)). The best thing is to compare the two cars on the same day, but we didn't have that luxury, so this virtual dyno shootout has to do for now. According to these results, the 2013 Accord (blue plot) just makes more torque and power pretty much everywhere in the rev range, and the gap widens considerably in the 4000-6000rpm range. This indicates superior breathing.

Plot #3 - 2013 Accord V6 EX-L 6MT Coupe (J35W2) vs 2007 Acura TL Type-S 6MT (J35A8)

Notes: These dyno runs were performed at the same dyno facility but several years apart, so there could be discrepancies there. Also, the '07 TL Type-S was tested during much warmer conditions, but the dyno software corrects for that difference using SAE conversion factors (in this case, the '07 TL Type-S' results were corrected upwards by a factor of 4%. There is zero correction applied to the 2013 Accord's results as conditions were close enough to the SAE's base conditions). Here, the Accord's engine outperforms the TL Type-S, on paper at least. The TL's J35 has the advantage of an extra point of compression (11.0:1), which means the TL Type-S requires Premium Unleaded. The Accord's listed 10:1 CR means it runs just fine on Regular Unleaded. For the dyno plots seen here, we don't know what type of fuel was in the tank as the car was delivered to us with a full tank. On this day, the Accord's J35W2 outperformed the TL's J35A8, mostly in the 4000-6000 rpm range, but please note that even though the Dynojet is supposed to correct for conditions, it's possible that the extra ambient heat present during the TL Type-S testing could account for a bit more power loss due to the ECU possibly pulling some timing out for safety's sake. This is why dyno testing 2 different cars on the same day or under the exact same conditions makes for more valid comparisons. For now, even though it appears that the new Accord is about 5hp stronger than the TL Type-S, we'll call it a draw.
