Toyota Camry Hybrid review, test drive

Toyota is all set to launch its second hybrid car in India. Unlike the Prius however, this one has a lot to offer Indian car buyers. An ideal combination between a hybrid and a spacious entry luxury car, the new Camry Hybrid brings customers the best of both worlds. But what exactly is the Camry hybrid? On the outside, the Camry Hybrid comes with a few exterior changes to distinguish it from the regular Camry. It gets a completely different bumper with a wider air dam and restyled fog lamps with chrome inserts. Lower profile Yokohama dB-series tyres wrapped around larger, 17-inch wheels and there are proliferations of blue badges to help identify it as a hybrid.

The real change, however, is under the skin. Toyota’s 2AR FXE DOHC VVT-I 2.5-litre petrol unit is there (albeit slightly tweaked to accomodate the electric motor), just as on the standard Camry, but assisting it here is Toyota’s electric drive unit that is all but identical to the one found under the hood of the Prius. The electric motor however, is slightly more powerful. The total output for the hybrid system is 202bhp – 158bhp from the petrol engine and 44bhp from the electric motor. The hybrid system’s battery is nickel metal hydride and not lithium-ion, while the battery’s capacity stands at 6.5amp/hr. The battery pack itself sits behind the back seat. There are changes to the cabin too, as Toyota smartly has focused on providing plenty of features to rear seat occupants. You get three-zone climate control (driver, front passenger, and rear passengers), cooled front seats, cruise control, and powered rear seats that recline by up to eight degrees. The rear armrest houses the controls for the recline functions and climate control for the rear. There’s a sunblind for the rear windscreen that is powered as well. And you get manual side blinds too. A nifty feature that Toyota has incorporated is the ability to flip the front passenger seat’s headrest forward to give rear passengers a better view of the road ahead. As with the regular Camry, there’s also a button on the side of the electrically adjustable front passenger seat, allowing you to push it forward from the rear seat. So what’s it like to drive? Well, there are three driving modes to choose from – EV, Eco and Normal. In EV mode, you drive on the electric motor alone, and you’re restricted to 40kph. Throttle responses are smooth in this mode and it’s best for driving in traffic. Then there’s Eco mode. Here, the electric motor works well with the petrol engine and there’s enough power and torque on offer to make driving effortless, especially at the bottom end. The new hybrid system integrates smoothly and feels evolved, improved and more refined. This is especially true when transitioning between various modes. The performance is quite nippy, but the moment you accelerate harder, the car takes a bit of time to get going. This is due to the e-CVT (electronic continuously variable transmission) unit it is mated to, which takes a bit of time to catch up and waits for the revs to build up. That said, the rubber-band effect usually associated with this kind of gearbox isn’t as pronounced as with other CVTs. The third mode, Normal, essentially deactivates Eco mode. The car is a lot more fun to drive in this mode as performance improves dramatically. Toyota’s petrol motor has always been torquey and quick to get off the mark. Here, with the electric motor assisting it, it’s even better. Hit the gas pedal, or in this case a combination of throttle butterfly and an electric switch, and you are instantly greeted with a lot of enthusiasm. You get an instant shove in the back, that keeps getting stronger for a few seconds and the Camry moves forward with plenty of energy and enthusiasm. Remember, we are talking about a car that is being pushed forward by a combined drive power of 200 plus bhp. In fact, the Camry gathers pace so fast, you can easily touch 180kph without the motor breaking into a sweat. Also impressive is the ride quality on the Camry Hybrid, and that’s despite the extra weight it is carrying. It is comfortable and pliant, soaking up road undulations reasonably well and because the heavy batteries sit behind the rear passenger seat, there isn’t too much bobbing or pitching either.

The impact of deeper bumps is felt though and the suspension does thud over larger obstacles. Unlike the Prius, this car also enjoys being driven in a spirited manner. The steering is impressively direct and the Camry Hybrid holds on gamely in corners, even as you pile on the power. Brake feel isn’t the best, though. Under hard braking, you can sense the regenerative brakes working away and the brakes feel a bit spongy. But the brake feel has been improved over the years in hybrid Toyotas, and in the Camry, it’s definitely a step up over the Prius. That said, the long wheelbase and ground clearance (identical to the normal Camry at 160mm) could be an issue on bigger bumps if the car is full, since the suspension setup is on the soft side. In terms of efficiency, Toyota claims that the Camry Hybrid’s ARAI-certified rating is somewhere in the region of 19kpl, which is quite impressive for a car of this size. We expect real-world efficiency to be in the region of 12-13kpl. So, does the new Camry Hybrid deserve a closer look? Absolutely. While hybrids haven’t done well in India so far, this new Toyota has the potential to change all that. The Toyota Camry Hybrid will be relatively affordable to begin with, costing only 3.5 to 4.5 lakhs more compared to the standard car because it is assembled here. A luxurious hybrid saloon that’s comfortable, well equipped, really nice to drive, the new Camry Hybrid could actually be the start of something big.

VW confirms XL1 hybrid

This is VW’s radical, lightweight XL1 which promises an EU-certified economy of 111.16kpl and 21g/km CO2 emissions when it goes into limited production later this year following its Geneva motor show reveal next month. Powered by a 47bhp two-cylinder 800cc TDI engine backed up by a 27bhp electric motor and 5.5kWh battery pack, the two-seat car is claimed to have a Cd rating of just 0.189. First shown as a running concept two years ago, the XL1 is being built at the VW-owned Karmann factory in Osnabrück, alongside the VW Golf cabriolet and the new Porsche Boxster. The XL1 has a carbon-fibre body, weighing in at just 795kg and is some 3.8m long and 1.66m wide, only marginally smaller than a VW Polo supermini. However, it is only 1.15m high, some 129mm lower than a Boxster. VW says the XL1 has its top speed limited to 159.9kph, but that it can hit 100kph in just 12.7seconds. It uses aluminium double wishbone front suspension, a semi-trailing link suspension at the rear; carbon-fibre reinforced plastic anti-roll bars and ceramic brake discs. The XL1, with a 10-litre fuel tank, can travel for 49.8km on battery power alone and has a claimed range of 499km on diesel and battery power combined. Rough calculations suggest the XL1 is capable of a real-world 44.96kpl economy in ideal conditions. VW claims it requires just 8.3bhp to be able to maintain a steady 100kph. The hybrid system’s electric motor and its dedicated clutch are fitted between the 800cc two-cylinder diesel engine and the XL1’s seven-speed DSG gearbox. The lithium-ion battery is mounted in the nose of the car and can be recharged when the car is braking and coasting. In pure electric mode, the engine’s clutch disengages and the motor shuts down. The engine is brought back to life via what VW calls ‘pulse starting’, where the electric motor spins up to high speed and is coupled back to the engine, accelerating the idled engine to the revolving speed required for smooth starting. The extreme weight-saving measures include using carbon-fibre-reinforced plastic for the body, the skin of which is just 1.2mm thick. Aluminium crash structures are used front and rear and as crash beams in the doors, to absorb impact forces. The windscreen is just 3.2mm thick. VW says the XL1’s construction breaks down into a 227kg drivetrain (including the battery), 153kg running gear, 105kg electrical system, 80kg of on-board equipment, such as seats and instruments, and a body that weighs 230kg. Even the dashboard is made from a lightweight wood fibre material that’s just 1.4mm thick.
