Seems like this is the on the same batch as mine?

The engine lights up the spec box with 306 horsepower at 6800 rpm, 268 pound-feet of torque at 5200 rpm, a 7500-rpm redline and an EPA rating of 19 city and 26 highway when backed by the five-speed automatic. That makes the G35 more powerful than nearly all of its six-cylinder rivals, including the BMW 330i, Audi A4 3.2 and Mercedes-Benz C350. The Lexus IS 350 also packs 306 hp, but it makes more torque, 277 lb-ft, at a lower 4800 rpm; and according to the EPA, it gets better mileage (21 city/28 highway).

As you would expect from the above paragraph, the G35 blows all 12 doors off its German rivals, while the Lexus matches the Infiniti's performance. Our tester tore up the track with a scorching 0-60-mph run of 5.6 seconds and a quarter-mile performance of 13.9 seconds at 102 mph. The last 330i we tested, which had a six-speed manual, was nearly a second slower in each test.
