Toyota Fortuner: Diesel Engine Performance
Mated to a 6-speed manual transmission, the 2.8L engine (2755 cc precisely) is simply going to be default choice of the enthusiasts. This is the same block as available in Innova Crysta but the combination of 2.8L + MT is exclusive to the Fortuner. Where the difference lies? Well, it is the state of tune. This engine makes a higher peak power at 175 BHP @ 3400 RPM, with a peak torque output of 420 Nm for MT and 450 Nm for AT (1600 - 2400 RPM), with ARAI certified FE numbers ticking at 14.29 Kmpl for MT and 12.9 kmpl for AT respectively. Yes, the torque figures for the manual version are lower by 30 Nm as compared to its automatic counterpart, which makes a higher peak torque at 450 Nm. Don't be surprised, it's the dimwit slush box AT that works really hard to make sure the manual car feel and is quicker – Yes, it's a slushbox which just want to shift up as soon as possible. We have had a really short experience with the diesel AT; hence this report will primarily focus on the MT.
Press the clutch pedal, hit the engine start button and it's a car quake. You guessed it right, the entire car will shake and the gear lever will shake even more violently at its position (gearbox is a chassis mounted component after all and cab is separate) like any other body on ladder frame rear wheel drive SUV - Yups, it's absolutely normal. Like the previous gen Fortuner, the gearlever in this car too works as a vibration massage tool and you can enjoy a proper vibration massage while on the drive (again a normal behavior for RWD UVs with manual gearbox). What will plant a smile on your face is the way in which the gear lever moves to left when you release the throttle on the go and then again to right when you feed in the throttle again, you need to put your hand on the lever to feel it moving this way. Comparably, the AT version makes you feel a bit better, there are only some shakes with which the hulk tells you when he is waking up or going back to sleep (engine off); there are no vibes on gear lever etc - well, that's also absolutely normal for RWD AT's.
In the MT version, what you will particularly like is that the gear lever is no longer a truck inspired piece as in the previous generation car, it looks a bit better now (but Toyota could have made it look beautiful). While the previous gen Fortuner used to make you move a bit with slightly longer throws, the current gen car will make sure that you remain a bit relaxed (still throws are on a longer side though). Rest what we liked in this gearbox is the precision of gates, I tried making many quick shifts and not even a single time I had to put any extra effort or the gear lever tried to get stuck at any point - 4/5 to Toyota for shift action. Where 1 mark got deducted? Well, the throws are still longer with that reverse gear going all the way up (again it's normal though, for 6 speed ones with reverse on the top left) and the clutch travel which I particularly found a bit on the longer side and not a very smooth affair, you will become habitual of it within 15 minutes though.
Coming to the driving experience, this engine is a bliss - enough said. Although the newer engine is smaller than the outgoing one, but you will never feel this difference while on the drive. This 2.8L block with MT makes a peak torque of 420 Nm from 1600-2400 RPM (BTW, Crysta has a wider peak torque band from 1200-3400 RPM, but with a significantly lower torque figure), hence overall the throttle response is very predictable, what we particularly liked is the way Toyota has managed to conceal the turbo lag. I just wrote that Crysta has a wider peak torque band, but I guess the Fortuner also has to offer similar figures for even wider rev range (the one we are talking is peak range after all). Want to feel it? Well, engage third gear at 25 Kph itself and slowly release the clutch, you will notice that the Fortuner will keep moving at around 25 Kph without any throttle input. Now hold your breath and bury your right foot. Wow! Initially, till say 1000 RPM, there will be slight vibes, between 1000-1200 RPM, the throttle response is a bit dull (You are not any ways supposed to drive at that rev range) but you can feel the power building up while the rev needle slowly goes past the 1000 RPM mark.
After 1200 RPM, you can feel power building up, 1300 feels decent and you can start the mission overtake. At around 43-44 Kph, you are at 1500 RPM. Back off the throttle, hold this speed and bury again - a blast follows! Suddenly the Fortuner starts surging ahead with a brilliant pace and you start laughing like a mad monkey. 2000 - 3000 - 4000, shift up and start moving ahead. That said, at 4000 RPM in third gear, you are nearly at 120 Kph (I can see the XUV owners laughing again and feeling good about the performance of their XUV). So what we discovered? Well, overall drivability is just brilliant and it is between 1500-3500 RPM that all the fun lies in. Redline is at a conservative 4400 RPM but you never get an urge to push till that point, simply shift up between 2500-3000 RPM and enjoy the 420 Nm of twist surging you ahead with a brilliant urgency.
On the other hand, the AT diesel has a higher torque on the paper, but it's the gearbox, which takes the fun quotient away from the equation. Na na, it is also a quick car and responsiveness is also good. Then what is wrong? Well, the only thing wrong about it is that it doesn't shift down as quickly as say, the one in Endeavour. Oh yes, the Endeavour with that massive 3.2L block is quicker than the Fortuner, be it in any iteration - Endeavour simply demolishes it with that sheer power out of its 3.2L engine which is nearly 18% bigger than that of Fortuner. Just like that in the Innova Crysta, the gearbox in the Fortuner too is a bit slow to respond. You press hard, wait a second and it shifts one gear down, then it decides to shift one more and then the car surges ahead with a brilliant urgency any ways, thanks to the heady power figures. Some may say that paddle shifters do help, well, yes they do and they do it brilliantly. They are nice when it comes to up-shifting or down-shifting, but expecting them to offer you the flexibility of the manual will be utter foolish, at times, they simply decide not to listen to you until the threshold speeds are reached - overall it is a smooth gearbox and owners who drive sedately will actually love it.
Cruising ability is the highlight of Fortuner diesel, the MT car had 100 kph speed attained at hardly 1600 rpm in sixth gear, while the AT one seems to have got even higher overdrive and hence 100 kph comes a shade above 1500 rpm itself. What is the best part is that, you are smack at the beginning of the meaty torque band and hence, you just need to press a bit and Fortuner will make sure that none of the highway overtakes are a cause of worry for you. Anyone who has driven the older Fortuner extensively, is definitely going to be caught by surprise here, looking at the relaxed cruising ability and the responsiveness of the engine even at the mad side of speeds. There are 3 driving modes too with ECO mode and PWR mode being common to both AT and MT, while the iMT mode is exclusive to the diesel manual.
iMT or Intelligent Manual Transmission is the actual party trick of the Fortuner MT diesel. What this mode does is simply matching the revs so that there is a smooth and jerk free transition while shifting the gears. In the turbocharged vehicles, especially the ones with heady torque figures like in the Fortuner, getting a jerk free shift; especially while trying to drive a bit hard (you can shift jerk free in any vehicle at 1500 RPM) or in higher mid range, one needs to be very careful while shifting to match revs so that there is a jerk free transition, but still that is not attained in every attempt. What if the ECU matches the revs for you? Well, this is something that both self as well as chauffeur driven customers will appreciate. With the iMT light blinking in the instrument panel, I shifted from 6th to 3rd at 90 Kph and voila, as soon as the lever was in place and I started releasing the clutch, the engine rpm went to 3000 mark - what a nice shift! Try this in any car and see if you can make a smooth shift in this condition. That said, iMT also needs time to help you and it's better if you release the clutch after the gearshifts in a gentle manner, if you are shifting quickly with abrupt clutch releasing, the iMT won't be able to help you much. Yes, it will still decrease the overall jerk that you would have got with the iMT deactivated.
