My first task of gas was not too great...

330.3 miles driven in 14.593 gallons. 22.6 mpg. Mixture of city and highway driving with a heavy foot at times. Hybrid Sport Rwd. My second tank is doing much better so far. 350 miles driven so far and I'm on 1/4 of a tank

I haven't had to fill up yet but it current shows I'm averaging 19 mpg, which is a HUGE (albeit disappointing) improvement over the 15 mpg it was averaging the first day I drove it. The dealer rep said it was likely that low due to how long the car had sat idle in the dealership for various reasons. I'm expecting it to continue to improve until it reaches the noted 23 mpg average.

It took over a quarter of a tank to drive the 80 miles home from the dealership!! I'm now nearly 300 miles on the first tank with about a quarter tank left.

My Q50 is a Premium RWD

Would be nice to hear how everyone is doing but I am not sure if it'll be accurate already since we are still in the break in period! I myself have been mixing sport and eco for a while now and still @ half tank with mostly city driving since I got my car from the dealership! Ill be able to contribute next fill up which will probably take a while! :D

How many miles have you driven it since you left the dealership

I am not sure but I think about 100 miles and a little over 1/2 tank still left!
Q50 AWD non-hybrid
180 miles, shows 1/2 of tank

Don't trust MPG shown. You need to fill the tank couple times before it will show correct numbers.

Agreed. But I will say that last Saturday I did a 250 mile round trip on a half tank of gas including sitting in stop and go traffic on the way home for more than an hour.
:eek:
1st tank was 372 miles and filled up 15.2 gallons (mix of hwy, city, back roads & beating the **** out of it a little). I have 114 miles on my second tank and I just hit 3/4 tank.
beating the **** out of it a little
:D:D so much fun.

first tank, 305 miles... computer said 30.2... mostly highway miles from dealership to home (215 miles).

45 miles into second tank... computer says 28.7. this has considerable more playtime in it.

(configuration in signature line)
The dealer rep said it was likely that low due to how long the car had sat idle in the dealership for various reasons.
Sat idle as in, shut off? Or as in, the engine was idling.

Sat idling (engine on but not moving).
Average mileage is 31.6 with 850 miles on the clock. When I get in the car I plug in my iPhone and then start the car. She idles until all Apps are loaded or 30 seconds have elapsed. During that time I select Sport mode and fasten my seat belt, and check the coolant temperature. Then we're in drive and by the time the coolant temperature is in the normal range we're moving and heading into battle, re, um, local traffic.
Speed limits near my home in the woods near Boston are between 25-40. Local secondary roads here lend themselves nicely to driving in "EV" mode. I step on the accelerator and bring the car very quickly to the posted speed limit (cannot exceed 4000 rpm... Yet!) and then let off the accelerator, keeping just enough pressure on the pedal to maintain speed. Then it happens; the tachometer falls to zero rpm as the green "EV" indicator illuminates, and we continue forward until the battery needs a charge. Almost a quarter of the miles travelled so far are in EV mode, which surprises me. Sometimes I don't even realize we've entered EV. Last weekend we drove to CT, then to Providence, RI, then back to CT, and then home to Boston, all on less than a tank of gasoline. I really didn't expect this. Really!

Can you elaborate on the conditions when the car is in ev mode only? What speed are you going? Is it in ev mode when you're accelerating or cruising only? What is your ev odometer at? I'm asking so many questions because mine really only goes into ev only mode when I'm slowing to a stop and the gas engine comes in with the slightest pedal pressure. And even when i have cruise control at 75 with a full battery charge, it is gas only. Would be helpful if you can give many different scenarios when you are on ev only. Thanks

Hmmm...u were able to average 31mpg with u on sport all the time?

I sure cant get there. 31 on first take on highways home from dealership in standard mode. 26 on the second tank, mostly on roads 25-45mph in standard mode. All computer calcs, haven't calculated myself.

These mpg threads are always difficult to interpret... So many variables!

My salesman told us, and he seemed to be pretty well trained on the Q50, that it will only go into EV up to 63mph. I haven't verified that anywhere else, but experience has proven him right.
Hi Q50Aggie. Yes, I'll elaborate. Based on previous experience with a hybrid Highlander I found a method of driving that seems to work for me. I accelerate quickly on gasoline to reach the 25-40 mph speed limit on our local secondary roads, and as soon as I reach the speed limit -let's say it's 35 mph - I let off the accelerator pedal so that that speed is smoothly maintained, and the engine turns off and the EV light illuminates, and I drive like I have an egg between my foot and the accelerator once the car is in EV mode. If a hill is coming up and nobody is behind me (don't be a Prius driver!) I'll allow the car to decelerate slightly so that I don't come out of EV mode, and I try to make up for that deceleration on the downhill by pressing gently on the accelerator to make up any speed lost on the uphill. If I attempt to accelerate while in EV mode past a certain point (you'll get to know that point by watching your Power/Charge meter) the gas engine comes on. I have almost 200 miles on the EV odometer. At secondary road speed limits (25-45 mph), for me, the EV works well. But it's rare for me to achieve EV on the highway unless I'm drafting another vehicle or on a downhill slope. Fortunately, most of my driving at present is on local secondary roads and I cheated by having a little previous experience with hybrid tech.

Hi gbert15. Yes, it's true. It's been Sport mode since the beginning. I like be steering setting and the shift schedule.

I really didn't expect this car to have the mileage I read about, nor the mileage I'm experiencing, but I'm pleased that she does so well on gasoline, and I enjoy playing the "game" with the EV mode. It's fun.

My average keeps creeping up and today I am at 24.9 mpg with over 700 miles on the car.

I did get it up over 100 today and it was pulling strong and as smooth as butter.

Matt, it is nice to hear about your methods.

I definitely enjoy EV mode around the parking lots and when the car is going about 60 on the highway and the ICE goes to sleep but I am having too much fun to test the mpg boundaries.

In any case, this car is doing way better on gas than my IS350 ever did.

Also, today my boss saw the car (he drives an E63) and was totally digging the look, the wheels and the color.

Yea man! I think I need to learn the car a bit more and time my accelerations and my braking properly! When to hit the gas or when to ease up on it!

Nice! Thanks for the tip! Gotta try it out! Ive been driving on eco mode most of the time and I dont think I am near the same gas mileage as u are getting! Ill test out your suggestion and see what I get! Thanks for the info man! Much appreciated! :)

The mpg of hybrid will stabilize after the 1200 miles breakin period.
