2017 Toyota Prius Prime quick take: All about efficiency

It won't thrill, but it will get more than 50 mpg

What is it? The Prime is the most expensive and technologically advanced Prius to date. It'll go 25 miles on battery power alone.

Key Competitors: Chevrolet Volt, Ford C-Max, Lexus CT

Base Price: $33,985 As Tested: $33,985

Highlights: The Prius Prime Advanced uses a 1.8-liter Atkinson-cycle I4 to supplement its two permanent-magnet AC sychronous motors. MPGe is rated at 133 and it will uses electric power up to 84 mph.

Our Opinion: What makes the Prius Prime 'Prime?' It’s the most-expensive Prius available and Toyota calls it the “ultimate” Prius, saying all materials and the hybrid tech and whatnot are optimized for efficiency. The Prime has a bigger battery to double range on pure electricity to 25 miles -- good, but still not as good as the Sonata plug-in or the Volt. Toyota claims Prius engineers targeted the 25-mile range based on research showing that distance meets 50 percent of U.S. commuters’ needs.

The Prime drives like, well, a Prius. In other words, it is what it is -- all about efficiency rather than fun. When I got in it, it was charged up so I never heard the engine, just silent EV cruising. So I didn’t experience what I remember from previous Prius drives like the strangely revving engine, spinning CVT, nasty, grabby brakes, and general lack of oomph. In EV mode I actually thought the car wasn’t bad for zipping around town. The brakes felt much better than I remember, throttle response wasn’t bad and – surprise! – the agility in corners wasn’t horrible either. I also thought the steering was quite good, another surprise. Still, a sport sedan? Certainly not. But it’s not supposed to be.

As for that $33K sticker, yes, I gasped. The Prime’s base price is $27,100, though, and there are the tax credits. They vary according to what state you live in but the federal credit seems to average about $4500. So we’re looking at $22,600. That’s gettin’ there…
