2012 Toyota Prius Plug-In: Parsing The EPA...
Whether you're buying an all-electric vehicle or simply want a mild hybrid to save a little on gas, there's a lot of choice in between.
The 2012 Toyota Prius Plug-In sits virtually in the center of these choices, with range-extended electric cars and battery electric vehicles above, with full hybrids and mild hybrids below. With the car now on sale in the U.K, we took the opportunity to get behind the wheel once more.
Familiar
Behind that wheel, and indeed before you even clamber inside the car, the Prius Plug-In is all very familiar.
For many, this will be a good thing--including Toyota. With so many Prius models roaming the streets, a car that drivers clearly feel comfortable with is the ideal platform from which to improve hybrid technology. It's clearly doing something right, so why change things too much?
On the outside, that means bodywork that's near-identical to the regular Prius, with only detail changes and an extra 'filler cap' hiding the charge port to give the game away. If you already like the way the Prius looks then you'll like the Plug-In too, though some of the extra silver details--door handles, front bumper trim--look a little out of place.
Inside, it's pretty much all standard Prius--a swooping, futuristic dashboard, comfortable seats, plenty of space and a tiny drive selector protruding from the raised center console.
Trunk space hasn't suffered despite the larger battery. Compact Lithium-ion cells replace the usual nickel pack, and Toyota quotes a negligible reduction in space, thanks to the slightly raised trunk floor.
On the move
It's much like a regular Prius to operate, too. Starting the car results in very little sound, as the car defaults to EV mode. The main difference is that it isn't as keen to leave EV mode as a regular Prius, and the sensation of accelerating with reasonable zeal without the engine kicking in is a pleasant one.
The new 'EV City' mode extends this ability further, designed for city-going buyers who don't want to hold everyone up as they crawl away from every stop light trying desperately to keep the car in EV mode. It does still have limits--boot the gas pedal and the standard Prius 1.8-liter engine will still fire up to assist your progress--but it's now possible to drive normally without the engine kicking in at all.
That includes driving up to higher speeds. Toyota quotes a maximum of 51 mph in EV mode, around double that of a standard Prius--though we'd not be surprised if it could do more still, when backing off the gas at higher speeds.
Performance is as you'd expect--in other words, it's no rocketship, but there's enough to make progress. Toyota quotes a 0-60mph time of around 11 seconds, and you'd have to put up with the CVT-induced drone on the way there. But in most scenarios, the engine is either off, or quiet enough so as to barely intrude at all.
Have an opinion?
I still don't understand the 95 mpge (blended mode) rating of the PiP. I wonder if you could run the PiP on electricity alone what the mpge rating would be. But in any case, it shows the weakness of the "blended" mode used in the PiP.
0.0947gallons/11 miles (electrical equivalent gals.)
0.0220gallons/11 miles (gasoline)
____________________________________
0.1167gallons/11 miles (electric and gasoline).
It is this last number that translates to 95 MPGe. So by these numbers, 19% of the energy (gallons if you must) comes from the gasoline. Not insignificant even during the first 11 miles.
If you could exclude the gasoline (and you can't) PiP would be 116 MPGe. So I think if the Prius could avoid using the gasoline, the number would be somewhere between 95 and 116 MPGe.
Yesterday I was driving home in my Volt. Cruising on the hwy at about 76mph with very littel traffic on any lanes.. Coming up to a light blue Prius Plugin cruising in the Middel Lane (out of the 3 lanes) with no traffic around it. I got curious and slowed down to behind that car and see how fast it was going. Guess what? EXACT 62mph!!!
Additionally, in the above scenario where the PiP is more economical than the Volt in mileage above some number of miles in the 70's, at that mileage, the PiP is hardly better than a regular Prius.
The one benefit I see is in very short trips, like to the store, where maybe you keep the ICE from coming on. I always hated that in my Prius because those short trips give you the worst mileage.
Other than that, I don't really get the PiP.
Had I pulled away marginally more gently, I've no doubt that the engine wouldn't have kicked in at all in the city/rural mix on the test.
Naturally, it's one of those "your mileage may vary" situations.
The "old and slow" image of Prius will NOT help the cause.
