Driving the 2.0L four-cylinder diesel
Volvo has made it clear that the SPA platform will only take the 2-litre, four cylinder engine at the most. This will potentially alienate US customers who love those big engines. No six cylinders, and the 4.4L Yamaha V8 is now dead as well. Volvo will increase performance via an electric motor or additional turbocharger / supercharger (instead of cubic centimetres). Still, there's nothing to match the creaminess or sound of a 6-cylinder engine and enthusiasts will be disappointed with its absence.
With Volvo, it's all about focus on modularity - the same engine is designed for petrol, diesel, hybrid and CNG! It is produced at a dedicated engine plant & nearly 70% of all parts are common. That is potentially a huge saving in costs; important for Volvo as it doesn't have the financial muscle of say, Mercedes. India gets the engine in D4 tune. That is 187 BHP @ 4250 rpm and 400 Nm @ 1750-2500 rpm. Not too impressive for this segment, and its competitors offer more power / torque. The D5 which belts out 232 BHP and 480 Nm with the Powerpulse and an all-wheel-drive system will come later. The diesel is mated to an 8-speed Aisin automatic gearbox driving the front wheels (four wheels in case of the D5).
The large 'Dash to Front Axle' measure means the engine sits a little back (unlike an Audi). We were told that non-service parts will take around 10 working days to arrive:
The tactile experience starts with turning the car on. I repeat, turn it on! You turn the cool knurled square knob to the left and the car starts up. Unlike a button which you could accidentally switch on or off by a mere touch, you need to deliberately operate this knob. The engine starts up with a muted thrum from the inside. Externally, it is as loud as the BMW 520d. Being new to the car and its controls, it was still very easy for me to get the optimum driving position and place the car.
Our test area consisted of narrow highways around Jodhpur. Gently floor the accelerator and you are greeted with oodles of torque. The Volvo picks up pace pretty quickly. However, at the 1600 rpm level, there is a strange jerk, after which she picks up power again and the maximum torque slams in. The same jerk happens as you slow down. Once you know about it, you know how to manage it. However, the jerk manifests in different ways in the various drive modes. Let me discuss this further.
There are 3 Drive Modes:
Eco - This mode brought the worst out of the car. The engine tended to upshift too quickly with a miserly fuel map. Progress was jerky; it was like driving in 5th gear all the time. The car was not smooth and you felt as if you were strangling the engine. The 1600 rpm flatspot was all too obvious.
Comfort - The car was more pleasant to drive, but that flatspot kept popping up as the car accelerated. Suspension is a little floaty.
Dynamic - Our pick. The engine is responsive, it changes gears at higher rpms and bypasses the flatspot most of the time. Body control is a little tighter, but not by much.
The engine's maximum torque band is between 1750-2500 rpm. While cruising at 100 km/h, the diesel is rotating at 1800 rpm. Very near that flatspot. I suppose it is a good enough excuse to go a little faster!
When it comes to handling, the problem with the luxury car segment is that every car is trying to ride like a Merc, grip like an Audi, turn in like a BMW and thrill like a Jag. In trying to do everything, there is always one parameter that is deficient. The brief for the Volvo team was to optimise things for a relaxed car for any kind of journey. This is where the Volvo excels. It has decent, if not neck snapping acceleration, but enough to get you out of any situation. The gearbox changes were smooth (although a bit biased towards upshifting). The Tip-Tronic function is far from hyper-responsive; still, you do know that the gearbox will respond in adequate time.
One thing that amazed me was how the car shrank around you, very similar to a Mercedes. It was easy to place and hustle into bends. The suspension handled all the bumps easily. During our 120 km journey on roads ranging from state highways to unmade roads and unscientific speeds breakers, I scrapped the car only once. Go over a bump, the car does not even shudder or shake. While talking about safety, in the hotel there was an S90 which had hit something hard (it was not an animal). Suffice to say, all it had was a bent bumper. No pictures as the car got covered up later that day.
The S90 holds its speed well. Show it smooth curves and the car holds its line. Actually, the electronics nag you to hold its line. Depending on the clarity of the road markings, the Lane Assist will remind you if you cross the line without indicating. As you veer off-course, the steering vibrates and you get a pulsating hand massage. The steering will then tug and gently take control. The radar based safety systems have been disabled so the S90 can save you...but not conquer you.
Being a front wheel drive car, I was expecting the steering to be numb. On the contrary, it does have a meaty if slightly artificial feel to it. It is not too heavy. You feel you are in control and the car goes where you point it. Turn-in is very neutral and it is biased towards slight understeer (it's no BMW). It responds well to inputs, but don't expect the S90 to beg for harder cornering. I tried a few sudden swerves and the car merely shrugged them off. Body control is good. The front end does bob a little up and down, yet the air suspended rear is well planted. The brakes are excellent. Great feel, very progressive and can wipe off speed smoothly and quickly.
Summarising, the Volvo will lack the 10/10ths for the keen driver, but it can hold its own. I did not feel underwhelmed by the engine at any point of the drive. But then, one does expect something special when spending this kind of money and the engine won't 'wow' you. Further, if I had been on the Delhi-Agra expressway, I might be saying something different. We came out of our 4 hour drive at twilight without any aches (a little stressed though as we needed to look out for chinkaras, foxes etc.). The air-conditioning kept us cool at 34 degrees and those seats were really comfortable. The S90 is a worthy competitor...but then, the new E-Class & 5-Series are just around the corner. Volvo are right now aiming for 250 bookings in India.
