2010 Mercedes-Benz E63 AMG Sports Sedan Debut


AMG is kicking-off the 2009 driving season with a new superstar: shortly after the launch of the new E-Class, the AMG high-performance brand of Mercedes-Benz Cars presents the new 2010 E63 AMG.

This dynamic sports sedan impresses with outstanding performance, thrilling handling characteristics and advanced technology transferred from its sibling, the SL63 AMG high-performance Roadster. The E63 AMG makes its U.S. sales debut in November 2009.

The new E63 AMG distinguishes itself from the standard Mercedes-Benz E-Class sedans with a newly developed AMG RIDE CONTROL sports suspension with electronically controlled damping, revised front suspension and unique exterior and interior design.

At the same time, Mercedes-AMG has achieved a significant reduction in fuel consumption of almost twelve percent for the new E63 AMG, thanks to the precise application of several fuel efficiency improvements. With its unique combination of pioneering driver assistance systems, the E63 AMG further consolidates the brand's leading position in the field of automotive safety.

The AMG 6.3-liter V8-engine in the new E63 AMG develops an output of 518 hp and a 465 lb-ft of torque, matching the outstanding figures for the SL63 AMG. The high-performance Roadster has also transferred its AMG SPEEDSHIFT MCT 7-speed sports transmission to the new model. This transmission replaces the conventional torque converter through the use of a multi-disc wet start-up clutch. In conjunction with the four individual driving modes, rev-matched shifts and RACE START function, the resulting, direct connection to the powertrain delivers an extremely emotional and high-performance driving experience.

The AMG MCT drive unit is unique in this segment, and provides dramatic performance figures: the E63 AMG accelerates from standstill to 60 mph in just 4.4 seconds, with a top speed of 155 mph (electronically limited). The fast-revving, naturally aspirated engine with a displacement of 6208 cc impresses with its agile responsiveness, muscular power delivery and high redline. The AMG V8 sound is a thrilling partner for mile after mile, while the smooth-running engine guarantees renowned Mercedes long-distance comfort. A newly designed water cooling system ensures maximum endurance even under the enormous dynamic stresses of the racetrack.

Fuel consumption cut by almost twelve percent
Despite 11 hp of additional output versus the preceding model, the E63 AMG showcases several advancements designed to improve fuel efficiency, including on-demand delivery of fuel and alternator management with recuperation of engine power during overrun. In-engine friction is also reduced by the AMG-exclusive twin-wire arc spray coating process used to coat cylinder walls.

The AMG SPEEDSHIFT MCT 7-speed sports transmission also makes a decisive contribution to fuel economy: a multi-disc wet clutch running in an oil bath replaces the previous torque converter. This unit responds extremely rapidly, directly and without the losses typical of a torque converter transmission thanks to its low rotational inertia.

The transmission is equipped with four driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) and "M" (Manual), which can be selected using a rotary electronic switch in the AMG DRIVE UNIT. Partial suppression of individual cylinders by interrupting ignition and injection during gearshifts under full load contributes to considerably faster shift times. In M mode the AMG SPEEDSHIFT MCT 7-speed sports transmission allows gearshifts to be performed in 100 milliseconds.

In the even more fuel-efficient driving mode Controlled Efficiency, the transmission shifts the gears with deliberate smoothness, and the transmission control unit is programmed to perform early upshifts to keep engine speeds as low as possible.

At the same time, the AMG SPEEDSHIFT MCT 7-speed sports transmission met the most demanding requirements where driving dynamics are concerned: fast and precise multiple downshifts ensure first-class agility in conjunction with the automatic rev-matching and RACE START function: this enables the E63 AMG driver to call on the maximum acceleration potential automatically.

Electronically controlled damping system and a new front axle
Sporty or more comfort-oriented? The driver of the new Mercedes-Benz E63 AMG is not obliged to accept any compromises in this respect. The AMG RIDE CONTROL sports suspension copes equally well with the dynamic cornering of the racetrack and more comfortable, sedate driving. High performance and typical Mercedes long-distance comfort go together as an extraordinary synthesis in the E63 AMG.

This is made possible by the newly developed AMG RIDE CONTROL sports suspension. While new steel spring struts are used on the front axle, the rear suspension features AMG-specific air springs. The advantage of this solution, which is exclusive to AMG, is that the front spring struts ensure more sensitive responses while the rear air struts with their automatic level control system keep the vehicle at a constant height, irrespective of the load.

A new, electronically controlled damping system automatically varies the damping characteristics according to the driving situation, reducing the roll angle of the body. The result is instant adjustment to provide the best possible ride comfort together with the greatest possible agility. In addition, the driver is able to choose between the three suspension modes of Comfort, Sport and Sport plus at the touch of a button.

The E63 AMG is also equipped with a newly developed, unique front axle with a 2.2 inch (56 millimeter) wider track, a tubular stabilizer bar, new control arms, new wheel bearings, newly-designed bushing geometry and kinematics and new wheel location for more negative camber – thereby providing more grip when taking turns at speed.

The AMG-specific kinematics also ensures significantly more precision. This is a highly sophisticated axle design whose principle has already proved its worth in the C63 AMG. The rear axle likewise has more negative camber, optimized elastokinematics and a new subframe mounting for greater stability at the physical limits.

Newly developed power steering and individual 3-stage ESP®

For more direct responsiveness, the speed-sensitive rack-and-pinion steering is also a new development. The steering ratio of 14 : 1 is 22 percent more direct (quicker) than in the standard production models, while a more rigid steering column plus the reconfigured characteristic mapping of the speed-sensitive servo assistance ensure better steering precision and improved road contact.

The 3-stage ESP® familiar from the SL63 AMG and C63 AMG enables individual settings to be selected – with clear benefits in terms of driving pleasure combined with the same high level of handling safety. The ESP® key in the AMG DRIVE UNIT allows the driver to choose between "ESP ON", "ESP SPORT" and "ESP OFF" – with the currently active mode shown in the central display of the AMG instrument cluster.

Perfect deceleration even during performance driving is ensured by the AMG high-performance braking system with 14.2 inch, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested compound (two-piece) construction technology is used at the front axle. Outstanding grip is ensured by the 18-inch AMG light-alloy wheels with a width of 9 and 9.5 inches and mixed tire sizes of 255/40 R 18 at the front and 285/35 R 18 at the rear.

Decidedly dynamic interior and exterior
The purposefully dynamic design of the E63 AMG is fully in keeping with the vehicle's impressive technology. The front aspect is characterized by 17-millimeter wider fenders bearing "6.3 AMG" lettering, the new AMG front apron with large intake air apertures and the AMG-specific daytime driving lights in LED technology. In conjunction with the optional Bi-Xenon Headlamps with Active Curve Illumination, the E63 AMG is equipped with tinted main headlamps.

The striking visual presence is further enhanced by the AMG side skirts and AMG rear apron with a black diffuser insert. As a hallmark of the brand, the AMG sports exhaust system has two newly designed, chrome-plated twin tailpipes.

The new interior of the E63 AMG is an exciting blend of high-grade materials and functional sportiness. Exclusive features include electrically adjustable AMG sports seats with improved lateral support and the AMG sports steering wheel in a four-spoke design with AMG shift paddles.

As a completely new feature exclusive to the E63 AMG, the AMG selector lever has one-touch logic. Directly adjacent to it in the center console is the AMG DRIVE UNIT, which provides adjustments for the MCT sports transmission, the ESP functions, the suspension setup and the AMG driving modes. Standard equipment also includes high-grade leather upholstery in three different colors, the AMG instrument cluster with an AMG main menu, door entry sills with AMG lettering and a sports pedal cluster – both in brushed stainless steel.


Even more individuality with tailor-made AMG extras
Customers can select the optional AMG Performance Package, which includes the following:
• Lightweight, forged 19-inch AMG light-alloy wheels with size 255/35 R 19 tires at the front and 285/30 R 19 at the rear
• AMG Performance suspension with stiffer spring rates
• AMG rear axle locking differential with 40 percent locking action
• AMG Performance steering wheel in a three-spoke design
• Top speed raised to 186 mph

Active and passive safety at a new level
The E63 AMG traditionally meets the very highest expectations with respect to active and passive safety. Standard features include the new drowsiness detection system ATTENTION ASSIST, the unique preventive occupant protection system PRE-SAFE®, Brake Assist PLUS, eleven airbags and crash-responsive NECK-PRO head restraints. Optional safety features can bring the vehicle to a level unprecedented in this class with Lane Keeping Assist and Blind Spot Assist systems, the PRE-SAFE® Brake with an automatic emergency braking function, Adaptive High Beam Assist and Night View Assist PLUS.

2009 BMW 335d Fuel-Efficient Sedan Review

Today's diesels, like the BMW 335d, are powerful, clean and fuel efficient, and have overcome previous drawbacks.

Dr. Ronald Golden, my periodontist, had one question beyond the usual inquiry into how I am going so very wrong with his brushing technique.

"Where do you get the diesel fuel?"

Told that BMW's new 335d is my current test car, Dr. Golden, a long-time BMW driver and auto enthusiast, is curious and wide open to the concept of a high-torque engine powering the superb 3-Series chassis. Chasing all over the city for diesel fuel, though, he doesn't fancy.

My usual Petro-Canada self-serve station doesn't offer diesel, it's true, but the Loblaw's just a few blocks further does. The former is 1.7 km from home, the latter 2.8 km, so for me it's no big deal. But how far Dr. Golden's nearest diesel outlet is out of his way requires some research.

And on the topic of FAQs, another is how long your hands stink after filling up. Before the sulphur content of diesel fuel was greatly reduced to 15 ppm in September, 2006, handling a diesel left a lasting stench. The reduction of sulphur has erased the stigma.

A personal experience is illustrative. BMW Canada supplied a filler adapter with our test car because some diesel pump nozzles won't fit. A full-serve attendant at a Sunoco station on Whitby's Thickson Road demonstrated that by sticking a finger in the filler and depressing a doodad, you could insert the nozzle without using the adapter and suggested I try. Thereafter, my finger would have condemned me socially for the remainder of the day, prior to model-year 2007. Today, not a whiff.

Many BMW fanciers will march past such concerns because the 335d is such an exceptional drive. As word spreads of its powerful throttle response and wonderful fuel efficiency (along with the silky ride and handling associated with other 3-Series models), drivers new to the brand will shop the car as well.

It does fall short of this EcoDriver column's standard of consuming no more than 10 litres/100 km in our city area driving. The 335d's EnerGuide city rating is 9.0 L/100 km, which qualifies it for consideration, but driving in the depths of winter, we averaged 11.2.

Considerable spinning of the rear wheels is a factor. Slush freezes overnight, capturing the Bridgestone Blizzak snow tires in icy cavities. The test car is well and truly stuck. Applications of salt, kitty litter and scrap Christmas tree branches purchase no traction. Finally two neighbours push the car free.

Which introduces another FAQ: is all-wheel-drive available in combination with the diesel? Not in the 3-Series in North America, not yet. The company's product planners chose to introduce diesel in only two models in the United States and Canada, the rear-drive 335d and the towering X5 wagon with all-wheel-drive.

This sedan is special. The X5 offers real advantages in practicality, but in terms of driving sensation it is not comparable to the 335d. The perfectly weighted steering, the balance in the handling that makes the car feel slotted into the road, the compliance regardless of surface irregularities, makes the 3-Series the international standard for premium cars of its size.


The twin-turbo diesel motor truly enhances the package. Its 265-horsepower rating is impressive, but the extraordinarily meaty throttle response is attributable to the 425 lb-ft of torque that is felt at only 1,750 rpm. The 3-Series' strongest gasoline engine, by contrast, has more horsepower at 300, but not nearly as much torque at 300 lb-ft.

The only comparable diesel-powered sedan in North America, the Mercedes-Benz E330 BlueTec, isn't a direct competitor. The Benz is larger, leans more to luxury than sportiness and occupies a higher price range as well: $68,100 compared with this car's base $49,700. It's rated at 210 hp and 388 lb-ft of torque, and has the same 9.0 L/100 km EnerGuide city rating as the 335d. It, too, is not offered here with all-wheel-drive.

Acceleration to 60 km/h, EcoDriver's usual measure of in-town get-up-and-go, averages 4.1 seconds in the 335d. Such effortless acceleration affords a measure of safety in accident avoidance, as does superior braking, and the 335d offers premium performance in each over less-expensive vehicles with similar fuel efficiency.

Various electronic stability controls that are standard equipment also come into play in our icy test week. Corner too quickly for the Blizzak winter tires to avoid skidding and the stability control quickly restores control. Indeed, BMW's advanced control technology renders this rear-drive sedan reassuringly easy to drive in winter's worst. Cold starts at -15 C are instantaneous. Waiting for glow plugs to warm up - once a diesel ritual - has gone the way of the stinky finger.

One new peculiarity is a subdued whirring noise sometimes heard from the rear of the car after turning it off, related to the tank that injects urea (commercially known as AdBlue) into the exhaust to eliminate nitrogen oxide emissions.

This diesel meets California air standards - as does the Mercedes-Benz using similar urea injection. The AdBlue is routinely topped up by BMW dealerships during annual services. Sharp-eyed observers will spot the pop-out access location on the driver's side of the rear bumper cover.

Any departure from the norm can cause a consumer to look elsewhere - and perhaps all the more so in a premium-priced sedan. BMW expects its globetrotting customers to have taken note of the predominance of diesel-powered luxury vehicles in Europe, and believes a test drive will make it obvious why this is so.

As for Dr. Golden's first concern, a few minutes on the web turned up a Shell station a few blocks south of his office at Yonge and St. Clair - 1.1 km away.

A final FAQ: isn't diesel fuel more expensive than regular gasoline? In our final fill-up, the price of a litre is 86.9 cents at the Sunoco on Thickson Road "we serve" pump. The station doesn't have a diesel among its "serve yourself" pumps where regular gasoline that day rounds off to 81 cents, premium 89 cents and Ultra 94 premium 93 cents.

On this day, at least, fuelling the diesel test car costs less per litre than would a gasoline-powered 335i with its mandated premium fuel. And remember, fewer litres are required with the diesel's superior efficiency. The price paid for its fuel, then, is part of the pleasure, along with its powerful character.

2009 BMW 750Li: The Best Luxury Sedan

The 400-horsepower BMW 750Li has rear-wheel steering. Below 40 miles per hour, the rear wheels can turn as much as 3 degrees opposite the direction of the front wheels, thereby reducing the big car’s turning radius.

I'm quite certain that somewhere right now, emotionally shattered BMW technicians are gathering in a church basement for a support group, huddled around the cookies and the coffee urn, their hands fairly vibrating with frustration. For as well deserved as is the title Ultimate Driving Machine, BMWs also have earned the reputation as the Ultimate Hangar Queen, taking up residence in dealership service bays and sending mechanics over the crumbling edge of insanity. Hello -- sob! -- my name is Dieter and I'm a BMW tech . . . . Hello, Dieter, keep comin' back. . . .

Yes, BMWs have middling initial quality and distinctly less-than-middling reliability -- so sayeth J.D. Power -- but people still buy them and adore them, because they are inarguably spectacular cars. Even the BMWs that I loathe are great cars. The new 135i is uglier than a Radcliffe glee club, but it's also fierce, fervid, delicious, a bottle of Bollinger that's lost its cork.

And then there's this car, the 2009 BMW 750Li, the flagship of BMW's starfleet, which might be -- one hates to draw lines in this particular sand -- the best luxury sedan in the world. Oh, sure, it could be better. It could run on the tears of disgraced CEOs or cure warts of the keister. But as an executive saloon, as a synthesis of power and grace and ease and prestige, the new 7-series demands that we reset our calipers, raise our ceilings and throw out our measuring sticks. There is now a new standard.

And yet, the 750Li boldly/daringly/foolishly leverages its greatness on the fulcrum of one of the company's perennial weaknesses: electronics. This car comprises a blazing amour fou of control modules, sensors, microcontrollers, solenoids and mechatronic actuators, all wired together with the CAN-bus network from hell.

Our fully optioned $110,170 test car provides an acute example. Among the systems: night vision display with enhanced pedestrian detection; active blind-spot detection; lane-departure warning; park-distance control; head-up display; adaptive headlights with high-beam "assistant"; three high-resolution cameras on the rear deck lid and front fenders.

Of course, there's an 80-gigabyte, hard-drive-based navigation system, satellite radio and premium audio system; and a completely redesigned version of the multifunction iDrive controller (the previous system was nicknamed "iQuit").

My favorite? The integral active steering system, which is to say, rear-wheel steering. Below 40 miles per hour, the rear wheels can turn as much as 3 degrees opposite the direction of the front wheels, thereby reducing the big car's turning radius. Great for parking and tight city traffic. Above 40 mph, the wheels turn in phase with the front wheels to increase handling responsiveness, cornering and agility.

Does integral active steering perform as advertised? Has Hasselhoff had work? This car runs like mighty winged Pegasus, carving mountain roads and dicing switchbacks as if it were an M3 with a pituitary problem. No big car has ever had so much rail-to-rail slaloming agility, such effortless composure at the limit. It's uncanny, it's eerie, it's surreal.

Indeed, the effect of all these electronics is to knit together a kind of digitized meta-reality where the surly bonds of physics have slipped a bit, a place where this enormous, heavy sedan can dance like a sports car. Think of it like the world of "The Matrix," inside of which Keanu Reeves can fly, or act.

And so we arrive at the truest portrait of the 750Li: half machine, half machine code; a kinetic sculpture, partly aluminum and steel, partly a stream of zeros and ones. Wonderful, epic, historic.

But can you trust it?
I really don't know. On the one hand, I'm utterly smitten by the technology. I love piloting a leather-lined spaceship with a 20-way adjustable captain's chair with heating/cooling and massage function.

There are moments on the interstate at night -- when the ghostly thermal-imaging night-vision display is on, the head-up display is reading out navigation messages, the lane-departure warning system is gently reminding me to use my turn signals, and all is bathed in serene LED cabin light -- that the 750Li really feels like something that comes after the Automobile.

Still, I'm nagged by doubt. All of these exotic systems, such as the head-up display (Nippon Seiki), lane-change warning (Hella) and night vision (Autoliv) come from suppliers in Japan, Germany and Sweden, respectively. The 750Li is practically the U.N. of Tier 1 suppliers. Considering the state of global comity, a question occurs to me: Can they all get along?

Bear in mind, all of this gear is overlaid on the car's, the brand's already fraught electronics: the e-throttle-equipped 4.4-liter, 400-horsepower, twin-turbocharged V8 with variable valve timing on intake and exhaust cams; the adaptive six-speed ZF transmission; the adaptive dynamics system, which itself has four distinct modes (Comfort, Normal, Sport and Sport+), which ratchet up performance thresholds for the engine, transmission, brakes, steering and stability control. The braking module governs anti-lock, traction and stability control, brake "drying," brake-fade compensation. . . . It just goes on and on.

What few buyers appreciate is how difficult systems integration is on a car like this. For the BMW 750Li to work, every system and subsystem has to mind-meld with the others in a cold chatter of instant, endless algorithms, faultlessly, every time, forever and ever, amen. No wonder they go buggy.

So when I say the 750Li is the best luxury sedan in the world, imagine a weather-balloon-size asterisk. I guess, as long as it starts, it is.
