I had a 95 Maxima V6 with manual transmission.
Now I have a new Camry 2.5L four cylinder, with an 8 speed automatic and rather extreme fuel economy engineering...
Variable oil pump - 15psi most of the time, increases when the engine is heavily loaded, seen 45psi
0W-16 oil
Electric Water Pump - reacts with temperature
Electronic Thermostat to go along with it.
Port and Direct injection - sometimes uses one or the other (rarely) or both(?) (often)
8 speed auto that seems willing to go into lockup in any gear at any speed, depending, doesn't necessarily report an unlock to shift.
Variable valve timing (some electric rotational doo-dad) on the end of both cams. Reading goes to 50 degrees.
Variable speed radiator fan.
Playing with an OBDLink LX with Toyota extensions to watch all this stuff operate.
There may be more I'm not remembering at the moment.
The SalesLady asked "How do you like it?"
I said "It feels like a rent-a-car."
The radio isn't anything to write home about. That's OK, Rush Limbaugh came through clearly. Four speakers, one in each door, by your feet.
It's quiet at 60, and reports like 50mpg, wind noise at 80, drops into the 30's
