2020 Mercedes-Benz GLE450 Prototype

What's really remarkable about the GLE's off-road performance isn't the kind of situations it can get itself into and out of; it's how easy it feels from inside

The new GLE-Class really is that good, even in prototype form.It starts with an all-new platform called Mercedes High Architecture, or MHA, but not necessarily all-new ideas. Indeed, the big party trick was born out of the road-only S-Class. Mercedes is calling it E-Active Body Control, and it takes the S-Class technology a big step further. On the S, a forward-looking camera scans the roads for bumps, holes, wavy pavement, and more and adjusts the damping so that when the car arrives at the obstacle it can waft over the imperfection without disturbing the passengers. It does so using hydraulics to lift the wheels up to pop over a bump or push them down into a hole, then put them back where they belong as you come off the bump or out of the hole. In practice, it allows you to drive over a speed bump at 35 mph and barely notice it.

The new GLE advances this idea by replacing the S-Class’ central hydraulic system with individual, independent hydraulic systems at each wheel, allowing the computer to control each wheel separately from the other three and fine-tune the damping on a level even the mighty S can’t touch. Donut-shaped hydraulic accumulators fit around the dampers, and high-powered servos adjust the preload and rebound constantly to iron out the road. As an added bonus, the system is powerful enough that Mercedes engineers were able to get rid of the physical anti-roll bars and rely instead on the hydraulics.

Our well-appointed prototypes were fitted with both the fancy dampers and the optional air suspension (steel springs and fixed dampers are standard), which in most cases would’ve been handicapped by the also-fitted sport package with enormous 21-inch wheels staggered 275 and 315 front/rear in Pirelli P Zero SUV performance tires with skinny 45- and 40-section sidewalls. Instead, this big SUV rode like, well, an S-Class. Undulating pavement ceased to exist as the system kept the ride perfectly flat, while potholes and railroad tracks were reduced to small bumps, more noise than impact.

To truly appreciate how well it rode, though, I had to get out and ride in a current-generation GLE 43 AMG Coupe that was tailing us. Suddenly, the highways and byways around Birmingham, Alabama’s Barber Motorsports Park felt coarse, wavy, and seemed to have much bigger expansion joints, potholes, and bumps. The GLE prototype had simply been erasing them all.

I mentioned that E-Active Body Control does away with physical anti-roll bars, and it’s more than a technical curiosity. Among other things, it allowed the GLE engineers to crib another high-end Benz trick: Curve Control. Originally designed for the SL-Class, Curve Control lifts the suspension on the side of the car opposite the direction of the curve it’s taking (you turn left, it raises the right side of the car). This helps reduce some of the lateral g force on the passengers as you corner. On the SL, the system felt very abrupt, like the sudden banking of a roller coaster. As you turned, there was a push from the side of the car and you were jacked up on an angle.

The GLE engineers have thoughtfully refined the system to the point where it’s effectively invisible in normal driving. There’s still a hint of that abruptness in its maximum setting (Lean Level 3) at low speeds, but now that you can adjust the amount of lean, you can dial it back to your liking. Or you can simply choose another driving mode like Comfort or Sport if you don’t care for it or don’t need it. In especially sharp corners or emergency maneuvers, the computer temporarily and automatically cancels Curve Control until things settle down.

Road scanning is only active in Comfort and Curve Control driving modes, but don’t think everything goes to pot if you select one of the sport or off-road modes. The computer simply relies on individual wheel sensors, yaw sensors, steering angle, throttle/brake position, and more to continuously vary the damping rate for the conditions.

The sport modes are where E-Active Body Control’s virtual anti-roll bars really shine. Keeping any vehicle’s body flat in a corner is a task, and it only gets harder as the vehicle gets taller and heavier and the center of gravity rises. Make no mistake, the new GLE is a big SUV, but it corners flatter than your average sporty sedan. When a typical vehicle goes around a corner quickly, there’s both a lateral and vertical component to the body roll. Depending on which side of the car you’re on, you move slightly up or down as the vehicle leans in addition to feeling pulled to the side. The GLE eliminates that vertical motion, so all you feel is the sideways pull. At most, there’s a slight dip at the corner with the most weight on it, the outside front then rear as you enter and exit a curve.

With that kind of body control and an impressive level of grip afforded by the steamroller-spec Pirellis, our GLE prototypes handled shockingly well considering both their size and mass and the fact they weren’t AMG products but simple GLE 450s with a sport package. In most corners, it’s just grip and go. You can’t really attack sharp corners without getting a moderate understeer, but that’s to be expected. What’s unexpected is the amount of rotation the stability control allows in Sport+ mode when you power out of the corners. It’s like the GLE engineers knew there was nothing they could do about the front end but wanted to make up for it by loosening the reins on the rear end just a little. It does all this by stiffening the virtual rear anti-roll bar during sporty driving, though it will go back to stiffening the virtual front bar when speeds get high to promote stability.

Helping achieve all this is Mercedes’ new 3.0-liter turbocharged inline-six with assistance from an electric motor between it and the transmission. In addition to the natural smoothness of an I-6, this engine boasts seamless torque thanks to the electric assist and a unique and pleasing growl that’s throatier than your typical I-6. It’s matched to a nine-speed automatic and a standard 4Matic all-wheel-drive system that utilizes a new electronically controlled wet-clutch center differential that can send 100 percent of power to the rear and up to 65 percent of power to the front on pavement. Left-to-right torque distribution is handled by the brakes as both differentials are open.

Off-road, though, is where the real surprises show up. Here, the Benz engineers pull out the entire bag of tricks. On the dirt, the air suspension can raise to the highest of its six settings, 3.1 inches higher than normal ride height (it can also drop 1.6 inches below normal for easy entry and exit), the center differential can fully lock and send 100 percent of the power to the front axle if it needs to, and the optional two-speed transfer case can be dropped into its crawl ratio.

Don’t think the system gets dumb, though. Every sensor but the road-scanning camera is still active, and the damping is being adjusted constantly to deal with the terrain. To keep you out of trouble, low range and maximum ride height are a package deal and come with an electronic speed limiter of just 12 mph. The center diff, meanwhile, is constantly varying the front-rear torque split and fully unlocks when you’ve got the steering wheel turned to the stops to improve the turning radius.

With a set of optional Pirelli Scorpion ATR A/T M+S in a square 275/50R20 fitted on all corners and steel plates fitted under the engine and transmission/transfer case, the big GLE becomes a rounder, plusher G-Wagen off-road. On a moderately difficult trail, the GLE crawled over decent-sized rocks, forded deep water, dropped into crevasses, and climbed up and down very steep hills without missing a beat or dragging a bumper. I saw an indicated 45 degrees of downward pitch and 28 degrees of roll on various obstacles. We even backed up that 45-degree slope, just for fun.

You might think those open differentials would be a deal-breaker off-road, but like many modern SUVs, the GLE gets away with using the brakes as a limited-slip differential. Unlike many others I’ve tested, though, the GLE’s computer clamped down on a tractionless wheel in less than half a rotation and sent power to the other side, where others would’ve let the wheel spin a bit before realizing it had no grip.

What’s really remarkable about the GLE’s off-road performance isn’t the kind of situations it can get itself into and out of; it’s how easy it feels from inside. Coincidentally, I’d pre-run a Jeep trail the previous weekend in our long-term F-150 Lariat FX4 and the difference in passenger comfort was shocking. In the pickup, I was constantly being thrown violently from side to side in the front passenger seat as we traversed rocks, roots, bumps, and holes. In the GLE, in the same seat on a more difficult trail, I spent the entire ride taking notes on my phone and never once reached for a grab handle. The level of body control on the Benz is that good.

Then there’s the fun stuff. Dig deep enough into the off-road menus, and you’ll find a screen that allows you to control the height of each wheel independently with sliders. Ever watched a video of lowriders dancing on their hydraulics? It’s basically like that, if a bit less dramatic. Then there’s Free Driving Mode. It’s meant to keep you from getting stuck in deep sand, and it does that by making the car hop straight up and down surprisingly hard. The idea is to unload the tires slightly and let the sand get under them rather than pile up in front and cause you to dig a hole. I guarantee both of these features will be used to show off on pavement at some point.

I’d like to tell you even more about the new GLE if you’re still reading, but the terms of my access to these prototypes forbid it. What I can tell you about is what you can see if you look closely enough at the photos. Right away you’ll see the new car adopts Mercedes’ twin-eyebrow LED daytime running lights. Look closer and you can see that beneath the camo the dramatically sloping C-pillar—a calling card going back to the first ML-Class from which the GLE-Class came—is still there. Cast your eye down to the wheel arches, especially at the rear, and you’ll see the GLE has very wide hips to accommodate its massive tires. In all, it looks like a tall, beefcake E-Class wagon with a shorter rear overhang. Step back and you appreciate how well Mercedes’ designers and engineers have nailed the proportions.

Given its performance on-road and off, it should be easy to see why I was second-guessing myself. You just don’t expect this breadth of capability from a luxury SUV, or even a mainstream one. Few modern SUVs do this much, period, and fewer do it this well. I’m sure it’s got faults somewhere, and I’m looking forward to trying to find them when production models hit the road in the first half of next year as 2020 models.

2012 Mercedes-Benz A-Class Teaser Video

Mercedes-Benz released the first teaser video of the 2012 A-Class wrapped in QR Code ahead of the Geneva Motor Show

Mercedes-Benz released the first teaser video of the 2012 A-Class today, ahead of its world debut at the Geneva Motor Show.

The Mercedes A-Class is entirely wrapped in QR coded camouflage.  The A-Class prototype will be just one of many models making their way  through Germany as part of a contest. One winner will receive  a trip to the car’s unveiling in Switzerland at the Geneva Motor Show. To enter into the contest, people will download the “A-Class QR-Trophy” app from the Apple App Store or Android Market. Once installed, users can then collect badges by scanning QR codes from prototypes, Facebook and Twitter. In total, four different badges will be available and each of them will give you a single entry into the contest.

The 2012 Mercedes-Benz A-Class will be built on the new MFA platform which is also what the B-Class rides on. It is likely that, like the platform, engine options will also carryover from its big brother.  If this is the case, we can expect five petrols with outputs ranging from 109 PS (80 kW / 108 hp) to 204 PS (150 kW / 201 hp). There will also then be four diesels with 122 PS (90 kW / 120 hp) to 204 PS (150 kW / 201 hp).

Mercedes-Benz Climatic Wind Tunnels Create Extreme Weather Indoors

After 2 years of construction, Mercedes has taken 2 state-of-the-art climatic wind tunnels at Sindelfingen into operation

Have you ever considered the possibility that on those 100 degree days when you are stuck in traffic that your car might overheat or when you’re in a -20 degree blizzard that your car might also run into trouble?  Luckily, if you’re driving a Mercedes, you don’t have to worry about such trivial things like weather. Mercedes’ new testing facility at the Sindelfingen site is specifically designed to run prototypes through a myriad of weather conditions.  

Mercedes-Benz recently inaugurated two wind tunnels capable of temperatures ranging from -40 degrees up to 140 degrees Fahrenheit.  In addition to testing the Mercedes-Benz Prototypes against brutal temps, the test vehicles can also be hit with hurricane force winds up to 164 mph, heavy rains and snow.

The ability to run the prototype vehicles through at such an early stage allows Mercedes-Benz to move more quickly through the design and development process, only have to do real life road tests on components that have already proven themselves.  Another advantage of the new climatic wind tunnels is that they are designed to accommodate the use of hydrogen and therefore eminently suitable for all alternative drive systems of the future. Special sensors and an effective air extraction system mean that fuel-cell powered vehicles can also be subjected to exacting test programmes here.

Mercedes B-Class Prototype Spied Cold Weather Testing – Video

The prototypes show the evolutionary dimensions and proportions of the next B-class, one of five models planned for the MFA

It has been a couple of months since we brought you spy photos of the future Mercedes-Benz B-Class and thanks to our good friend Andrus, we have something better than photos. We have a video of the Mercedes B-Class B-Class prototype doing cold weather testing in Sweden. The all new Mercedes B-Class is expected to premiere in Frankfurt next year.

These hand-built B-Class prototypes show the evolutionary dimensions and proportions of the next B-class, one of five models that are planned for the new front-drive platform, referred to as MFA. The five passenger MPV will be the first model off the MFA, followed in 2012 by the new A-class, and then a junior SUV and a small saloon.

The MFA is a conventional unibody and replaces the expensive sandwich structure used on today’s A and B-classes. Because of the switch to conventional body engineering, Mercedes will drop its own front-drive engines, which were designed as part of the sandwich platform crash structure.

In their place will be a combination of existing in-house and small-capacity Renault engines. Over time the engine range will eventually include turbocharged 1.2-litre, 1.4-litre and 1.8-litre petrols, a 1.6-litre diesel from Renault and Mercedes’ 2.2-litre diesel.

Initially, however, sales will centre on larger-capacity Mercedes units, according to Stuttgart insiders. Gearboxes will be a six-speed manual and a six-speed dual-clutch auto in place of today’s CVT, both with stop-start.

The MFA is also being engineered to accommodate three alternative powertrains: plug-in electric (E-Cell), petrol-electric range-extender (E-Cell Plus) and fuel cell (F-Cell).

The basic dimensions of the new B-class are largely unchanged, as is the elevated driving position, but cabin space is better, thanks to a lower floor. There’s more flair in the styling, with tauter surfacing and more defined shoulder treatment, as previewed on the F800 Style concept at this year’s Geneva motor show.

The adoption of LED head and tail-lamps is an important exterior upgrade. The B-class also sticks with conventional doors all round, despite Mercedes experimenting with a sliding rear pair. Merc is also moving the B-class interior up a notch in quality with higher-grade plastics, trim, switchgear and controls from the C-class.

Ciento Once Prototype by GWA Is One of a Kind

Making careful changes to the original design and updating it with modern details, the"Ciento Once" was created

The Forgotten Gullwing. Back in 1970, this car was a hero, breaking all the records with its revolutionary Wankel diesel engine. A few prototypes where built, but never came out as a production model.

Arturo Alonso, GWA owner, felt that this beautiful and legendary car deserved a revival. Making careful changes to the original design and updating it with modern details, he created, what he calls, the”Ciento Once”.

Housed in a tubular space frame chassis, the power plant is a M120 Mercedes V12 engine with 408 HP, which can be admired trough a glass on the rear deck. The robust engine is paired with a 6-speed Cima H type transaxle and a special tuned exhaust.

The Ciento Once will feature a slightly shorter wheelbase than the original (103 in) and maintain the weight around 1,400kg. Assisted by the upgraded suspension with coil-overs, to adjust the ride and height, and the same braking set up as the S55 Mercedes Benz, this car will definitely be fun to drive.

The body will be hand made out of aluminum and includes the electric-operated rear adjustable wing to help it grip the pavement. For aerodynamics, a rear diffuser and front spoiler with a big air intake will guide the air flow into the radiators and then out through the hood vents.

The interior of the Ciento Once resembles the original from the 70’s with some updated features: carbon fiber seats covered in plaid, instrumentation modeled after a W120R MB (including the radio and the a/c control unit), brushed aluminum pedals, dashboard accent, and illuminated door sills.

Using the same set up as the SLS, the car runs on staggered GWA Type A wheels, 19X9 front and 20X11 rears, with 265/35/19 and 295/30/20 rubber.

The Ciento Once prototype, which will likely be one of a kind, will be painted in brilliant silver with black accents and matching interior.

2012 Mercedes-Benz B-Class Details Emerge

These hand-built prototypes show for the first time the evolutionary dimensions and proportions of the next B-class

Details of the next generation Mercedes-Benz B-class – the first Benz to be powered by Renault petrol engines – have emerged on Autocar. According to Autocar, the all new Mercedes B-Class is undergoing testing ahead of its Frankfurt Premiere next year.

These hand-built prototypes show for the first time the evolutionary dimensions and proportions of the next B-class, one of five key models based on an all-new front-drive platform, dubbed MFA. The five-seat MPV will be the first model off the MFA, followed in 2012 by the new A-class, and then a junior SUV and a small saloon.

The MFA is a conventional unibody and replaces the expensive sandwich structure used on today’s A and B-classes. Because of the switch to conventional body engineering, Mercedes will drop its own front-drive engines, which were designed as part of the sandwich platform crash structure.

Mercedes-Benz C 112 Prototype Video

Video of the Mercedes-Benz C 112 research vehicle that was introduced to the world at the IAA in Frankfurt, Germany

In 1991, the Mercedes-Benz C 112 research vehicle was introduced to the world at the IAA in Frankfurt, Germany.  The  C 112 served as a technological prototype – a test vehicle and super sports car all-in-one – and was capable of reaching a top speed of over 300 km/h.  Built in “near to series” conditions, the mid-engine racer was used by Mercedes-Benz exclusively for research purposes, and it was built with one goal: to positively influence driving stability using new electronically regulated assistance systems. The result? One of the systems pioneered on the C 112 is the Active Body Control (ABC Suspension), now in series production on a variety of Mercedes models.
