Lamborghini flagships are known to be notorious. Right from the Miura to Countach to Diablo to Murcielago would require you to have massive guts to go in hot into a corner, and great skills to get out of it facing the right direction. The Aventador on the other hand, would make you work, but it has a certain amount of sophistication for you to not have your heart in your mouth every time you saw a corner. The Aventador blended Lambo's outrageous behaviour with modernity.Don't pull out your swords after hearing this, but there was something off with the Aventador in the past years. It was a tad too heavy, the gearbox just wasn't as sharp and you know it isn't the sharpest knife in the set when you push it really hard. It needed some work. And now after six years of being around, this raging bull has been worked on to get some essential upgrades. And of course, a suffix - S.The new Aventador S is badged at 740-4. And that means, the massive 6.5-litre V12 mounted at the back of the car now churns out 740hp or 730bhp. Alterations to valve timings and variable intakes have been yielding in the form of 40 more horses. But there's been no change in the torque figures, it stands at 690Nm.Despite increase in power, there has been no betterment in the performance figures. If you want to hit 100kph, you'd still take an eye-popping and pant-wetting 2.9 seconds. And if you have 200kph on your mind, 8.8 seconds is all you need, and if still more road left, it'll do 300kph in less than half a minute. Outrageous? Not as much as its top whack of 350kph...Fortunately, Lambo has not started talking the forced induction language yet. And natural aspiration in the cylinders of that V12 means it can breathe more freely. With a bit of tweaking with the codes of the on-board computer, the rev limit has gone up from 8,350rpm to a fabulous 8,500rpm.The Italian designers have put in some work on the S and taken some cues from SV in terms of the external styling. Yeah, the design in the first place is outrageous and jaw-dropping. But to sharpen bits out furthermore, the grille and some other bits on the face have made way for new ones. Some bits on the bumper and diffuser are not only a visual treat, but also functional. There's now 130% more downforce, and in commoners speak, it means that the Aventador will stay more planted even while it does outrageous speeds on the straights and around the corners.The Aventador, in the yesteryears would show signs of vagueness while you push it on a racetrack. It had to deal with almost 1700kg of kerb weight going around. Lamborghini has found a way to tackle that problem. No, it's not what you think. They haven't shed off kilograms by chopping the feature list down or by giving fabric door handles or things like that. Instead, the Aventador S now uses a four-wheel steering system.At low speeds, the wheels turn into opposite directions and at high speeds, in the same direction. This, according to Lambo, increases agility at low speeds and helps in cornering at high speeds. This, virtually, decreases the wheelbase by 500mm as the wheels turn up to 3 degrees, and has the effect of the wheelbase increasing by 700mm at high speeds, pushing up the confidence and stability while throwing it around on a racetrack.In fact, this whole exercise of installing a four-wheel steering has helped enormously in making the Aventador the sort of racetrack monster and corner craver that flagship Lambos have always been.Even with this mid-life update, Lamborghini has retained the same gearbox to do the task of putting all the power that the V12 makes down to the road. It has seven ratios and is capable of changing the amount of torque it sends to either of the axles instantaneously. It's got one clutch and an ability to alter character to a fair amount. But when you compare to the new dual-clutch 'boxes of today, this feels like one of those last specimens of a near-extinct species. It tends to get a little too vigorous while giving you a cog change at high revs, and taking a blink more of time than it should. It lacks that last mile of refinement.Not much has changed in the cabin of the flagship Lamborghini. Not much needed to change, anyway. There's now an addition of a tiny button on the centre console that says 'Ego'. Lamborghini has added an Ego mode to the already existing three drive modes. It lets you choose what setting you'd like for the steering, suspension and engine. Yeah, just a whacky name to Individual setting mode.The Aventador S replaces the Aventador, and with the sort of things that Lambo has done to its flagship, it's bettered in every respect. It's now far better to drive, makes you work a bit lesser, can handle more speeds around a corner, and with the active rear-wheel steering, ups your confidence levels to a great extent. At Rs 5 crore (ex-showroom), the guys at Lamborghini have tried to give you the best that they have, and what comes standard with it is plenty of flashiness and flamboyance that Lambos ought to have.Specs6498cc, V12, naturally-aspirated petrol, 730bhp, 690Nm, 0-100kph\: 2.9 seconds, top speed\: 350kph, Price\: Rs 5 crore (ex-showroom)VerdictThe update has bettered the Aventador in every way. It's more confident around corners and tucks away its weight with the help of the four-wheel steering.
