2006 Infiniti M45 Driving Impressions
We spent most of our time in the 2006 Infiniti M35 Sport model, but we also drove an M45. Lower weight helps the V6 engine provide enough power to propel the M35 at a decent rate. The five-speed automatic transmission works well with quick shifting. Drivers who want more control can use the manual mode, which works better than in some cars as the shift lever has a short throw more akin to that of a manual transmission in a sports car.
We were satisfied with the V6's performance until we drove the M45 with the 335-horsepower V8. It's a rocket ship providing exhilarating acceleration. Not surprising, as Infiniti claims it is the most powerful V8 among its competitors. What's more the fuel consumption is only a couple of miles per gallon worse, no doubt because the V8 is not working as hard. Unfortunately it ups the cost by almost $7,000, compared to the M35 models. (BMW and Mercedes buyers also face a big premium for the more powerful engines.)
