volvo s60





Design & Engineering

Like all modern Volvos, the S60 is designed with a very aggressive, almost rakish profile. Almost no design cues are carried over from boxy Volvos of old, and there is a lot in common with the design language of the carmaker’s more recent cars like the XC60. Yes, the strong shoulder line and the chrome diagonal on the grille are still there, and the S80’s coupĂ©-like roofline is retained as well. But this is clearly a new design direction and it works superbly. We also like the way the nose of the car is tipped slightly forward too, giving it an aggressive stance.

The S60 was engineered when Volvo was part of Ford and, as a result, the car is built on the same EUCD platform as the Mondeo. The steel monocoque chassis uses MacPherson struts up front and multiple links at the rear, and the engines are located transversely, placed well back in the engine bay for better weight distribution. Using a Ford platform is no bad thing, especially if you want a car to ride and handle well. And Volvo claims this is its best driving car ever, its engineers having made a number of improvements to the S60’s chassis. These include a stiffer front sub-frame, stiffer strut mount tops, stiffer bushes, a 10 percent quicker steering rack and a new steering column that’s twice as rigid.

The petrol T6 also gets a Haldex four-wheel-drive system, which has a combined rear differential and clutch. Incorporated into this system is a unique ‘torque vectoring’ system, which works in conjunction with the yaw and roll sensors of the ESP or stability control program.

As soon as some understeer is detected, the torque vectoring system sends more power to the rear wheels so that the car can be pointed into the corner more easily. The idea is to use power rather than brakes to bring the car back in line. Weight distribution on the diesel front-wheel drive, however, is more skewed to the front, upto 62 percent of the weight resting on the front wheels.

Volvo, in all probability, makes the safest cars in the world and while this car is its entry saloon in India, the S60 comes with a suite of safety features, some of them unique to this car, which could shame even a Merc S-class (see box). And all that safety kit at this price
is phenomenal.

A shocking omission, however, is the lack of a spare tyre or run-flat tyres. At least BMW’s run-flats allow you to get to your destination at a reduced speed. Volvo only provides a puncture repair kit, not much use if you get a slashed tyre wall, something that’s quite common in India.

Interior

Sweden is famous for its classy and minimalist interior design, and the S60 reflects its heritage. For Indian tastes, the straight lines and simple form of the cabin maybe a bit too boring but there’s an appealing blend of high quality and robustness that makes it special. Swathes of brushed metal, especially on the doorpads and steering wheel, look really good and the ‘floating’ central console – a Volvo signature – stands out. The Cyclops’ eye vent at the top of the central console is also unique. What also add to the funky appeal of the cabin are the two-tone seats, with their tall anti-whiplash headrests.

As on all Volvos, the seats are among the best around, and thigh support and bolstering are very good. The seats, again feel a half- size larger than competitors and we found the front seats to be extremely comfortable even after a long day spent behind the wheel. Rear seat comfort is also very impressive. You sit slightly lower than say in a Mercedes C-class,but legroom, thigh support and especially lower back support are better. And the central transmission tunnel isn’t as obtrusive as on other rear-wheel-drive competitors; better for the fifth passenger.

The quality of the leather, plastics and metal bits is also very impressive, and we were hardpressed to find even a few cheap-looking bits on this car. However, some ergonomic oddities do exist. You can’t point the air-con vents as effectively as you’d imagine, the mass of buttons on the central console can be confusing, and the cream-coloured leather on the steering wheel is certainly a big mistake in India. It will get soiled in weeks. You do get a pair of large- size cupholders in the elbow box and the S60 has a front parking camera as well, which is unique. This video screen-based parking system also has a fantastic graphic overlay that tells you exactly how close you can park; a really nice feature for our congested cities.

The safety systems do their job but also feel like an overkill. While the BLIS (Blind Spot Information System) works well, flashing away to warn you about bikers darting down the left, the Lane Departure Warning is largely useless (as lane markings are far and few between!) and the Collision Warning is a bit too trigger-happy and beeps at the slightest provocation.

Performance & Economy

Volvo has two powerful motors on offer for the S60, and we’ve tested both. However, it’s the T6 with its 304bhp turbocharged transversely mounted straight six that won our heart. Mated to a four-wheel-drive system via a six-speed automatic, this potent motor delivers brilliant performance from anywhere in the powerband. The four-wheel-drive system is quick to channel power optimally to all four wheels and the motor belts out a thick wad of torque which is delivered with a sporty snarl.

Acceleration is strong enough to make passengers initially gasp and this turbo-petrol’s mid-range is nothing short of explosive. In a straight drag, the S60 eats the BMW 330i for breakfast and spits the Audi A4 3.2 out of its tailpipes. The C-class isn’t even in the picture. Get this – 0-100kph in the S60 arrives in 6.3 seconds compared to 8.10sec and 8.05sec for the most powerful 3-series and A4 respectively and the gap only widens the quicker you go. Another stat to commit to memory is the S60’s 0-200kph time of just 24.4sec which is quicker than even the BMW 535i! The S60 is a seriously quick car and that means you can have bags of fun behind the wheel, especially on an open road.

What makes the T6 even more impressive is the fact that this motor is very driveable at city speeds. There is very little lag and the engine feels responsive and always alert. The only fly in the ointment is the gearbox which feels slow at times and blunts performance. In ‘D’ the transmission hesitates quite a bit and you need to leave the lever in S mode if you’re driving in a hurry. Also, sorely missed on this model are paddle-shifters because it is in manual mode that the transmission feels best. While the T6 petrol revs comfortably to 6700rpm, it doesn’t spin as easily as a Bimmer’s straight-six and isn’t as turbine smooth either.

The 2400cc D5 diesel motor is less impressive and doesn’t set benchmarks like the T6. This five-cylinder diesel throbs more than a bit at start up and it certainly isn’t a silent as expected from a car in this class either. However, it does spin enthusiastically and smoothens up a fair bit but you are always aware of the odd number of cylinders firing under the hood. Also, noise levels are considerably higher than say on a BMW’s 320d which, in comparison, feels both silent and silky smooth.

As on the bigger S80, the D5 engine uses a pair of sequential turbos to force-feed the cylinders and the result is a class-leading power output of 205bhp. The surge of power in the midrange from 2000 to 4000rpm is truly impressive and this makes the car effortlessly lunge forward with just a dab of the pedal. Again, it’s the quickest car in its class (if you don’t include the potent but far pricier A4 3.0TDi) and takes a scant 8.19sec and 17.9sec to get to 100kph and 150kph respectively. The strong midrange also makes it a very good highway cruiser and passing other cars is just a prod of the throttle away. We just wish it was more refined and came with a slightly faster-acting automatic gearbox.

A turbo-petrol producing over 300bhp isn’t going to be frugal but the T6 didn’t turn out to be the guzzler we expected. In the city it returned a surprising 6.9kpl in the city and 11.1kpl on the highway, if you drive normally. Like most turbo-petrols, fuel efficiency is very sensitive to driving style and even the smallest bit of enthusiasm with the throttle pedal will send figures south. The D5 diesel was pretty efficient again returning 9.5kpl and 13.4kpl for the city and highway cycles respectively.
