BMW X6 Review


Review: BMW X6
What we have here is the updated version of BMW’s oddball SUV. First off, BMW doesn’t call it an SUV, preferring instead Sports Activity Coupe. And what’s new here? The kidney grille has gone back to the drawing board and returned looking a bit different. The fog lamps have been repositioned and the tail-lights are now LED. The X6 sits 10mm lower than the earlier model, reducing ground clearance to 212mm. The rest of the design stays identical to what it replaces.

Inside, too, it hasn’t seen too many changes apart from the choice of colours that you get for the leather upholstery, and the raised sports seats. There’s oodles of space in the front row but not at the rear. There’s no problem with leg- and shoulder room, but the sloping roofline robs you of headroom. If you’re taller than the average Indian, chances are good that your head will hit the roof.

In the features department, you get everything that you’d expect from a Rs 1 crore BMW. Like the iDrive multimedia system, head-up display, individual climate control on all four seats, rear seat entertainment system with DVD player and screen, the works.

The new X6 has also seen some changes that are more than skin deep. The 3.0-litre twin-turbo diesel mill is a masterpiece. It now churns out 301bhp and 600Nm compared to the earlier 235bhp. This is what diesel engines of the future will be – great-sounding, strong low-end, punchy mid-range and an equally strong top-end. And thanks to those two blowers, there’s no hint of lag throughout the range. The same engine does duty in the 6 series, but there, it develops 309bhp and 630Nm.

The engine is coupled to an eight-speed auto ’box. The shifts are seamless and the tranny does the downshifts willingly, especially in S mode. Power is transmitted to all four wheels efficiently, ensuring you don’t lose traction even on the tightest of bends. The screen will even show you the amount of torque being sent to the wheels.

For its size, the X6 40d is pretty agile off the mark. If you keep your right foot planted, it can hit 100kph in 6.18 seconds. This engine is not only about power, it’s decently fuel-efficient as well. Out on the highway, the engine will cruise lazily to return a healthy 10.5kpl. In the city, it’ll go 6.7km for every litre of diesel. On open road, it’ll cruise effortlessly at 180kph – you start feeling the stress on the engine only past 200kph.

Another engine option in the X6 is a petrol-powered 4.4-litre V8 that develops 402 horses and 600Nm of torque (the same torque output as on the X6 40d). The V8 sounds great, even better than the in-line six-cylinder diesel that we have here. The petrol 50i is capable of pushing the X6 to a ton from standstill in a claimed 5.4 seconds. Although the petrol is quicker, as is to be expected, the fuel-efficiency of the petrol naturally doesn’t come close to that of the diesel.

Having said all this, the X6 is good only on the road. Apart from the tall stance, it doesn’t have a low-range gearbox or ride-height control or diff locks, which come handy when you decide to go off-road.

The X6 stays true to BMW’s reputation for steering feel. The wheel is just the right size and feels nice to grip. And it weighs up exactly the way you’d expect it to, delivering healthy feedback around corners. The paddle shifts are ergonomically placed behind the wheel and let you shift easily even when driving a bit enthusiastically.

Despite the height, the X6 is confident with high-speed cornering and doesn’t easily lose composure. There is a bit of roll, but acceptable by SUV standards. Under panic braking, the X6 will come to a complete halt from 80kph in just 24 metres, putting some far lighter sedans to shame.

The X6’s ride quality feels unsettled and scarred tarmac travels all the way up your spine. But this settles down well with an increase in speed. Still, even then, the X6 will not be the most comfortable car for a long-distance trip.

With its look-at-me styling and huge proportions coupled to a highly capable engine, the package doesn’t come cheap – it’s a whopping Rs 1.10 crore (on-road, Mumbai, without optional extras). But opting for even a few of the extras, such as the Active Seat package, head-up display and adaptive LED lights, will send the price upwards by nearly Rs 10 lakh.

The X6 will be your choice of machinery if you love attention on the road. It’s a great driver’s car with good steering feel, tall stance and fine dynamics. But if someone else takes the wheel and you ride in the back, the X6 will disappoint tremendously.

The numbers
6cyl, 2993cc, diesel, 301bhp, 600Nm, 8A, AWD, 0-100kph – 6.18sec, 30-50kph – 1.72sec, 50-70kph – 2.12sec, 80-0kph – 24.39m, 2.74sec, 8.6kpl, Rs 1.10 crore (on-road, Mumbai)

The verdict
This mild refresh should put the X6 back in the limelight. Good driving dynamics but low on space and comfort.

480-horsepower BMW X6 ActiveHybrid World's Most Powerful Hybrid

Unlike the mainstream market where hybrid technology is used to maximize fuel efficiency, luxury carmakers have employed hybrid systems as a way to maintain or improve performance while making concessions to efficiency. The BMW X6 ActiveHybrid, due out for retail sale this fall, is a prime example.
2010 BMW X6 ActiveHybrid
Rated at a combined output of 480 horsepower and 575 pound-feet of torque, the big SUV uses a twin-turbo 4.4-liter V-8 engine and a nickel-metal hydride hybrid powerpack to claim the title of the world's most powerful gasoline-electric hybrid passenger vehicle. That's no mean feat, with contenders like Mercedes-Benz, Lexus and Cadillac in the space. The two electric synchronous motors contribute 91 horsepower/192 pound-feet and 86 horsepower/206 pound-feet, respectively.

Accordingly, it's no wimp at the stoplight strip, sprinting to 60 mph in just 5.4 seconds, and on to an electronically limited top speed of 130 mph. And it does it all while eeking out 22.8 mpg in the European combined cycle, about 20% better than the standard V-8's ratings. The improvement is due largely to the hybrid system's ability to run on electricity alone up to 37 mph, though the hybrid-specifc automatic stop-start function also helps reduce wasted fuel at idle.

Like its big, brawny brother the X6 M (read our first drive of the X6 M here), however, the X6 Hybrid's main problem is a very American one - weight. Racking up 400 pounds for the hybrid drivetrain in addition to the standard vehicle's 5,000-pound curb weight, it's impressive that the X6 Hybrid gets the fuel efficiency it does.

Prototypes of the vehicle were spotted frequently throughout its development sporting a huge domed hood where the electronics and diagnostics equipment lived. That's been mosltly solved for the retail version, with BMW packaging it all away tidily, though you'll still know the hybrid version from a distance.

The hybrid system employed by the X6 ActiveHybrid is a version of the Daimler-Chrysler-GM Two-Mode system that uses twin electric motors that can alternately provide extra power, charge the batteries at a 50kW regeneration rate, or trade power between each other as necessary. Tying the electrical side to the gasoline engine is a two-mode active transmission based on an electrical CVT and a standard seven-speed automatic transmission.

BMW unleashes X5 M and X6 M performance SUVs

We bet there are still thousands of BMW M fans out there reeling from the fact that the performance division is launch its first ever SUV model, and a turbocharged one at that. Those fans better get used to it fast as BMW has just revealed its new X5 M and X6 M SUVs ahead of their New York Auto Show debut.

The latest images reveal more aggressive overall styling and slightly lower stance for the performance pair, though there remains a healthy amount of wheel-arch gap. The hood, front air dam, and headlights are virtually identical on the BMW X5 M and X6 M.
2010 BMW X6 M
Unique 20in split five-spoke wheels, absolutely enormous brake discs that could pull double duty as pizza pans and a sporty rear diffuser/exhaust area add to the M-specific appeal. Inside, a two-tone leather treatment with M branding complete the first-ever M-SUVs.

Both models are powered by a newly-developed 4.4L V8 M engine delivering 555hp (412kW) at 6,000rpm and 500lb-ft (677Nm) of torque from a low 1,500 to 5,650rpm - enough to send the vehicles from 0-60mph in just 4.5 seconds.

This new M engine is the world's first with a pulse-tuned exhaust manifold encompassing both rows of cylinders combined with high-performance twin-scroll twin turbo technology. Two low-mass twin-scroll turbochargers are positioned together with the catalytic converters in the "V" section between the two banks of cylinders. By reversing the flow of gases through the engine from traditional arrangements, the intake and exhaust ducts are shortened and widened. The result is that pressure losses on the exhaust side are minimized.

This configuration, known as Cylinder-bank Comprehensive Manifold (CCM), offers quick turbo spooling, a linear build-up of engine power, and a broad, consistent torque curve by feeding each of the twin turbochargers with a "charge pulse" at approximately every 90 degrees of crankshaft rotation, rather than the more traditional "irregular schedule" of charging. Maximum boost pressure is set at 1.5bar (21psi).

BMW M engineers have also reworked the full drivetrain and chassis, adding new M-specific adaptive suspension, an uprated intelligent xDrive AWD system, and newly-developed Servotronic power steering.

Also featured for the first time on an M model is a six-speed automatic transmission, which for the X5 M and X6 M also comes with an electronic selector on the center console and offers three different driving modes – Drive, Sport and M Manual modes for absolute control of gear selection.

BMW X6 ActiveHybrid on sale by mid-2009

2011 BMW X6 Active Hybrid spy shot
BMW first revealed that its X6 SUV would be available as a hybrid model when it rolled out the X6 ActiveHybrid concept vehicle at last year’s Frankfurt Motor Show. The car has since been spotted testing in prototype form on both sides of the Atlantic and the latest spy images reveal a near-production ready version of the upcoming model. Now new details have emerged on the release date, which appears to have been moved up to mid-2009.

Previous reports had pegged the X6 ActiveHybrid's release for 2010, but a new report from Automobilwoche reveals that BMW is now planning to release the vehicle for sale in mid-2009. Pricing information is still unknown, but expect it to bear a premium over the standard X6, which starts at $66,200 for the V8-powered xDrive50i.

The new hybrid will feature BMW’s version of the modular two-mode hybrid system jointly developed with Daimler and General Motors and is expected to improve fuel efficiency by about 20% when compared to the xDrive50i, putting consumption in the neighborhood of 23mpg (10L/100km) in the combined cycle, a definite improvement over the V8 model's 18.8mpg (12.5L/100km).

Previous prototypes were seen sporting an oversized bulge on the bonnet, most likely to accommodate the new hybrid hardware. The latest prototype looks much more like the standard X6, although a small bump remains.

The design uses twin electric motors which can either be used to boost acceleration, charge the batteries or as a generator to mutually power each other. The two-mode active transmission is based on an ECVT electrical continuously variable transmission. The two operating modes, optimized for both high and low speeds, are supplemented by fixed transmission ratios.

BMW’s new-generation 7-series flagship had been expected to debut the new hybrid system late next year or in early 2010, after which it would filter across to more models such as the X6. With the new announcement, it appears that the X6 could be the first hybrid in BMW's lineup, although it's also possible BMW could be pushing forward the 7-series hybrid's debut as well.

A concept version of the 7-series hybrid was revealed earlier this year, revealing that BMW's hybrid system will initially match a 4.4L V8 engine to the electric drive system.

BMW X5 and X6 M to be revealed next month

BMW X5 and X6 M to be revealed next month

BMW just launched a microsite on the internet announcing that the high-performance M versions of the X5 and X6 will make their debut 30 days from now. Considering the New York Auto Show starts on April 19, that means both models will be revealed ahead of the show.

As revealed in the teaser video, the sport activity vehicles will be powered by a twin scroll turbocharged V8 engine, which just backs up our suspicions of the 500+ hp 4.4-liter twin turbo powerplant making an appearance in these SAVs.
