Toyota Innova Crysta: Diesel Engine Performance
Mated with a 5-speed manual gearbox, the MT variants get a 2.4 liter Diesel engine, that has a peak power output of 148 BHP (@3400 rpm), and a peak torque output of 343 Nm (@1400 rpm), with ARAI certified FE numbers ticking at 15.10 Kmpl. This engine is smaller than the outgoing engine, still producing around 50% more power and around 70% more torque than the engine it replaces. In terms of NVH, it is definitely better than what we had in the previous gen car, it is just more muted. Rest it still shakes on the start and the gear lever will still give you a vibration therapy (which RWD doesn’t, till this price point?)
Depress the clutch pedal and tap on start button. It that an earthquake? Nope; that’s a car-quake. The gear lever violently shakes at its place along with the cabin (gearbox is mounted with engine after, all to the frame) and that lever will remain shaky throughout. Not an issue, to be very precise; RWD LF UVs are like that only. That said, the clutch is on the lighter side and progressive in action, which definitely makes me happy. Adding to this, are the ECO and PWR driving modes, since the modes work in exactly same fashion in all three engine options we have tested, so we will discuss them at a later stage.
If you have owned the old gen Innova, then better rewire your brain before hitting the gas. Else this car is gonna surprise you by the way it puts down the power and torque. What has been the forte of Toyota diesel engines is their tractable nature and this engine follows the tradition really well. I just never, never ever shifted to the first gear. Every time I drove the car from standstill, it was in second gear. Speed breakers are easy to pass even for a low displacement diesel second cog, bigger rumble strips get tricky, especially when front wheel is in trough and rear one hits. I stopped the car there (believe me, XUV gave up), engaged the second and released the clutch. Initially it hesitated and a fell in idle revvs was observed, then Mr. ECU detected the chances of a stall and revs rose again, so did the front and rear wheels on the strips. Yes, Innova passed over it; with a hiccup, but still impressed us. With peak torque coming in at just 1400 RPM, we were surprised by the number of gearshifts the Innova crysta demanded , you can climb hills at 35 Kph in third cog; not a single hiccup.
You can drive on the highways right from 60 Kph to top speed in fifth cog itself. 100 kph comes smack in between 2000 and 2500; around 2250 RPM. 120 is seen somewhere around 2700 RPM and 140 Kph is seen somewhere around 3100 RPM itself in fifth gear. The older car used to do 100 Kph itself at over 2750 RPM mark. That said, the acceleration is brisk and even after you cross the 140 Kph mark, there is no tailing off in power. The Innova Crysta 2.4 still keeps on accelerating strongly and it’s only after you cross the 3750 RPM mark, you may feel that there is a tail off in the power delivery, don’t ask me where the needle is at that moment. 100 kph, for an instance came a shade over 13 seconds with 5 on board and AC on, which was the best we could manage. And taking the load into consideration, one can easily expect 1 second progress to 100 kph with drive on board, AC OFF and right shifts.
Kitna deti hai? As per MID readings, the fuel efficiency we achieved is as follows:
- City ECO: 11.2 Kpl
- City PWR: 9.0 Kpl
- Highway ECO: 15.8 Kpl
- Highway PWR: 10.4 Kpl
The 2.8L Diesel
Mated to the 6-speed slushbox AT is the 2.8 liter Diesel engine, that has a peak power output of 172 BHP @ 3400 RPM, and a peak torque output of 360 Nm (1200 - 3400 RPM), with ARAI certified FE numbers ticking at 14.29 Kpl. The 2.8l block is the same that we have got in the new gen Fortuner, albeit with a lower state of tune. The biggest differentiator with 2.4l is the NVH, especially due to the feeling of the shaky gearbox of 2.4, which is replaced by an auto ‘box here. At the start, the cabin shakes for sure but the NVH is actually good, at least the idle NVH. The overall insulation is better and you actually feel better in the brown and black cabin of the 2.8 as compared to the all black one that you get in the 2.4. Overall, the NVH, interior quality and the engine, they all do justify the premium pricing of the 2.8.
The six speed torque converter automatic promises a proper jerk free driving experience. The vehicle crawls at 7-8 kph speeds and that is good enough for city drives. Mind you, the throttle isn’t lightening quick to respond, there will always be a gap of half a second between when you put your foot down and the engine responds, well manageable and quite common too. Okay, talking business, this is a proper big bore boy and the peak torque comes at as low at 1200 RPM itself. This is one such an impressive block that whatever way and at whatever speed you drive it (Sane speeds I mean), put your foot down and the UV starts moving ahead with an impressive brute force (nothing matches it, absolutely nothing). Super tractable and impressively fast people mover this 2.8l engine equipped Toyota is.
The beauty of this engine and gearbox is actually their smoothness of operation and relaxed nature, if you love sudden bursts of power and acceleration, then better look at some DSG, this gearbox takes its own sweet time to decide the ratio. It is always like, bury the right foot, wait 1.5 seconds, it will shift two gears; one after another, and the actual performance comes in. But..and a big but indeed, when the performance comes in, you are literally riding on a never ending torque wave. That said, in the sixth gear, 100 kph comes somewhere around 1650 RPM and 120 comes smack at 2000 RPM mark. Press further and you get to see 150 kph right at 2500 RPM, with a strong but sporty sounding engine noise coming into the cabin coupled with some tyre noise.
Well, give up? No ways, press it further and you will be surprised by the way this car even goes past the 180 kph mark, that said; we had backed off as the empty and elevated stretch of the expressway was over. But yes, don’t try to check the top whack of this 2.8 on public roads. Take note, this gearbox is not tuned to drop more than one gear at a time and hence there will always be a downshift like one and then two; don’t expect third, it won’t do that and it even doesn’t need to do that either. In our performance runs, we managed to hit 100 Kph in around 11.3 seconds with 5 on board and AC on. We won’t be surprised to find out this car hitting the tonne under 10.3 seconds though, maybe even 10.0 itself.
