Robert Pepper’s 2016 Toyota Prius i-TECH review with pricing, specs, ride and handling, safety, verdict and rating.

In a nutshell: The prius is now one of many hybrids including several from Toyota, so it has been re-positioned as the most Eco-friendly and technically advanced car in its segment – and it is, more or less.

[review]

Practical Motoring Says: The Toyota Prius is has been the best hybrid for a while and this is the best Prius yet. It’s the most efficient, has a decent amount of tech but not quite enough to justify the headlines, has no significant disadvantages compared to a normal car, drives just as nicely and looks distinctive. It’s still not a cost-effective buy for the average owner, and doesn’t offer much fun either in the driving or the owning, but if it’s fuel-efficiency you prize above all else then this is your car.

Design

I think of the Prius as rather like a Hummer or a Lamborghini – all three are cars that get the owner instantly judged, even if for entirely different reasons. Such has been the way since the Prius first wafted its way onto the market, back in 1997.

Since then the car has been in continuous production, unlike several of its competitors, and with more than 3.6 million sold it has deservedly become the standard by which all other hybrids are judged. That will change, over time, as hybrid tech becomes as unremarkable as a diesel or petrol option, and in turn electric cars are now the new unusual.

Toyota themselves are rolling hybrid technology out across its range, already with Camry, and soon with Corolla later this year. In fact, Toyota has sold 8.6 million hybrids in total, and even the likes of Porsche and Land Rover now offer hybrids, although as a whole Australia’s take-up rate of the technology is well behind that of Europe and USA which gets plug-in versions of the Prius, hybrid Kluger and RAV4.

So if hybrids are just another drive system, where does that leave a car which is defined by its drivetrain? Global chief engineer Kouji Toyoshima says that “From a social perspective, we knew it was important to build on the role of Prius as an eco-leader”. Toyota also say that “the new Prius adds a fun-to-drive character while evolving the best aspects of the car’s ecological heritage”, and that “at the same time, we wanted to create a more emotional response with a design that is inspiring, passionate…perhaps even sexy”.

 

Room & practicality

Starting from the front we have a reasonable amount of storage; glovebox, door pockets and a nicely spacious centre console. The tiny gearshift and foot-operated parkbrake (yuck) don’t get in the way, and there’s a storage area for your phone in the centre which does inductive charging. So all the basics are up front, including a sunnies holder, but there’s nothing special or particularly impressive.

Moving into the second row and the outer seats are comfortable enough, if not overly blessed with legroom.  Adults are going to find the middle second row less than comfortable, particularly because of the limited headroom due to the sloping rear back, required for the low aerodynamic drag coefficient of 0.24.

There’s a 12v socket for the rear seat occupants, and two rear pockets on the front-row seats. But otherwise it’s all bland and beige, not really fitting with Toyota’s vision of the Prius as cool, eco, inspiring and tech.

At the back and the boot is spacious, and has four decent tiedowns. Again, that aerodynamic shape forces a teardrop design that means the hatch door is low. 

This car is no reconfigurable master of interior space, not least because under the second row seats is the battery. But it’s not cramped, and you mostly would never realise it’s a hybrid.

A nice touch is a cargo blind, which neatly stows away under the boot floor.

Compared to the previous model, this new Prius is 60mm longer, 15mm wider and has seats that are 55 and 23mm lower front and back.

On the inside

Given the Prius is all about being inspiring and cool it’s a bit disappointing to find no more than the basics. The 7″ touchscreen infotainment unit is the same as every other new Toyota, there’s no smartphone integration like Android Auto or Apple CarPlay, there’s no self-park function, no electric parkbrake, surround cameras or anything else to push the car ahead of the tech-pack. The only notable feature is the smartphone inductive charging and there’s just one USB port and one 12v socket.

The infotainment unit is the current Toyota standard and adequate, if not exceptional – response speed is acceptable, it’s fairly easy to use and looks ok. The unit has most of the basics covered, but again the Prius falls a bit short on its tech promise. What is covered, well and truly, is fuel consumption…every possible permutation of how much you’ve used when is displayed, somewhere, somehow. I have to wonder who actually uses all these displays.

The interior is well built but not exceptional, and Toyota have gone to some effort to create a futuristic design but appear to have got bored and given up once they did the centre dash.

Toyota do deserve considerable applause for using two different screens, one main unit in the dash and another further up below the windscreen. 

This is a great move because it allows you to have two displays going at once – for example, navigation and radio stations, and the smaller display does a good job of fulfilling its functions, although there’s not an exact 1:1 ratio of features between the two screens.

Cars with just the one display force you to constantly switch the display from one function to another which is distracting and tedious. More cars should be like this.

Performance, ride and handling

How it works:

The Prius is a petrol-electric hybrid, which means it has two engines – a petrol four-cylinder 1.8L and an electric motor. It can operate in the following modes:

• Petrol power to drive
• Petrol power to drive and recharge the battery
• Electric power to drive
• Petrol and electric power to drive at the same time
• Petrol and electric power at the same time, plus battery recharge
• Using braking or coasting power to recharge the battery (regeneration, energy harvesting)

In other words, pretty much every combination of electric and petrol engine can be, and is used. However, all this is entirely transparent to the driver and there is no manual control. You just drive, and the Prius works its magic.

The petrol engine is good for only 72kW and 142Nm, which are very small figures for a 1.8L motor. The Prius is, as hybrids always are, a bit heavy at 1400kg (the Corolla is 1300kg). But with the efficiency improvements, and allied to the electric engine which contributes another 52kW and 162Nm the Prius can’t be called underpowered as the electric and petrol engines work beautifully together.

Here’s what the in-car display looks like (more photos in the gallery below):

 

 

 

The fuel consumption for this new model has dropped from 3.9L/100km to 3.4L/100m – that’s not a huge difference in absolute terms, but it is in percentage terms and means more kays out of a tank. That’s the result of making improvements pretty much everywhere. The chief engineer, Mr Toyoshima, says “take the petrol engine for example. Outwardly, it seems it hasn’t changed, with the same capacity and basic design, but in fact we have taken its performance to a much a higher level – more complete combustion, less friction and better heat management. With this level of scrutiny, we have in fact made it the most thermally efficient in the world. Simply put, you get more power from every drop of fuel”.

Mr Toyoshima said other major elements also received the same close attention – transmission, electric motors and hybrid battery, which is now under the rear seats, freeing up storage space and improving the handling with a more centrally located centre of gravity. The air conditioning systems detects if there is a front passenger; if not, it will focus its energy on the driver alone, another efficiency gain. This can be overridden by the driver.

 

 

Aerodynamic drag has been reduced, including under the body of the car, and the electric power steering has also been tuned for efficiency. The steering is quicker now compared to the previous model so less turns of the wheel required.

 

Around town:

The Prius is an easy, quiet car to drive around the ‘burbs. You don’t lack for power, although this is no sportscar. Response to throttle is immediate, brakes are good, and while the tyres are optimised for low rolling resistance the car won’t run out of grip unless you really start doing things it’s not designed for – that’s thanks to improved suspension and a lower centre of gravity.

 

Every Prius has, in effect, engine stop-start tech. Many people dislike this feature, but in the Prius it’s fine because the petrol engine is cut as soon as you come off the throttle and coast, or brake so it doesn’t feel like a last-minute switch off. Then when you move off the car gets off the line instantly with its electric motor, and then if necessary the petrol comes in too. This is as distinct from the slight lag between throttle application and engine start in a car with stop/start that doesn’t have an electric motor.

 

One good point is braking. Most hybrids have an unnatural brake feel as the hybrid’s energy-harvesting system interferes with the pedal feel, but not in this Prius, you’d never know it was a hybrid.

Compared to previous Priuses this one uses its battery power more often and more effectively. In stop-start traffic you will often not hear the petrol engine for a while, even with acceleration in traffic up to around 50km/h. Beyond that the petrol cuts in again. Many other hybrids on the market barely use their electric motors, but in some cases the Prius barely uses its petrol engine.

There’s no hill start assist, and as the Prius cuts its engines at idle there’s no ability to ‘hold’ the car on a hill as you get with conventional automatics. The parkbrake is foot-operated.

You do get a heads-up display which shows speed and optionally, the state of charge of the battery. The dash is unusual because there’s nothing directly ahead of the driver, just a central display. However, it works well enough, although some of the text on the dash display is a bit too small and fiddly. Looks like the designers worked on high-resolution monitors and forgot drivers will need to glance at this while they’re meant to be driving.

EV Mode

 

On the open road:

The Prius’s handling has been improved, something Toyota are keen to trumpet, so now it handles like a modern 2016 medium sized hatchback. In other words, it’s gone from below par to on-par. It is in no way what you’d call a sporty or exciting drive, it’s just an easy cruise.

 

As we found at slower speeds, the car doesn’t hurt for power and will readily accelerate at 100km/h, but there’s no easy surfeit of grunt as you find in modern turbo-diesels. The active cruise control works well and is easy to operate. The seats are comfortable, and the ride is generally good; not wallowy, firm enough for control but certainly not harsh, and the only negative moment was a set of washboard corrugations on a broken bitumen road, but that’s not really Prius territory.

 

There is a new electric cruise function where up to 105km/h the car will, where appropriate, cruise on its battery. This is effective. If the Prius’ battery is charged it may as well use the power, whereas before it would tend to cruise with full batteries but not use the power at higher speeds.

 

There is no full-size or even a space-saver spare on our i-Tech, just a repair kit, but the base model does get a space-saver. Fuel is happily 91RON not premium.

 

The B mode in the gear selector stands for Braking and is used on long downhills where the engine can assist with braking.

 

Safety

The Prius does fairly well for safety with AEB, active cruise control, lane departure alert, blind spot monitoring (on i-Tech models only) and automatic high beam. The i-Tech also gets blind-spot monitoring and rear cross-traffic alert.

The lane departure alert is a bit over-sensitive and many drivers will switch it off. The automatic high beam is mostly effective but can be confused, so in trickier situations such as hills it’d be best to take control manually. Visibility is fairly good all round. Usability of the controls isn’t particularly intuitive, but once learned all the basic functions can be quickly and easily controlled.

A reversing camera is standard, and the car beeps when it reverses like a large truck…as reversing tends to be done on battery alone this is a good safety feature albeit a bit irritating.

ANCAP hasn’t rated the 2016 Prius yet but we’d expect a 5-star rating as all the Prius family has rated 5-star to date.
