Two new Mercedes-Benz sedans headed to North America

  Two new Mercedes-Benz sedans headed to North America Count on seeing the A-Class and AMG GT sedans in North American dealers next summerAccording to Automotive News, the upcoming Mercedes-Benz A-Class sedan will make the journey across the Atlantic and hit North American dealers next year. Exact details are few and far between, but the report suggests a base price under US$30,000 and it will be sold alongside the CLA-Class.

Announcement: Mercedes - AMG Project ONE . Unadulterated Formula One technology. The Mercedes - AMG hypercar – probably the most fascinating two-seater that will ever hit the road.

The Mercedes - AMG Project One (stylized as ONE) is an upcoming production sports car that will be powered by Formula 1 technology. It will be launched at the 2017 Frankfurt Motor Show. As it does have a F1 powertrain, it will become the first to do so.

Racing fans were not happy with the fundamental changes in Formula 1 engine regulations that were introduced for the 2014 season. The world’s preeminent racing class was about maximum speed and excitement—not efficiency and CO2 reduction, which was the focus of the new turbocharged 1.6-liter hybrid powertrains. Besides, the idea that “racing improves the breed” has been touted ever since the early 1900s; yet, other than rearview mirrors and disc brakes, racing innovations that have transferred to street cars have been few and far between.

The upcoming Mercedes-AMG Project One rewrites that history by bringing technology from the all-conquering Mercedes-AMG Formula 1 car to the street, with the most interesting and most direct technology transfer from the Grand Prix car being the engine. Current F1 regs dictate that the engine must be a turbocharged 90-degree V-6 displacing 1.6 liters. It must have four overhead camshafts actuating four valves per cylinder and pneumatic valve springs, and it cannot rev higher than 15,000 rpm. The bore size can be no greater than 80.0 millimeters, which means the stroke is 53.0 millimeters to achieve 1.6 liters. Only a single, direct fuel injector is allowed per cylinder, but it can operate at a maximum pressure of 7250 psi. In the race cars, this engine produces some 700 horsepower at around 11,500 rpm with about 25 psi of turbo boost.

The Mercedes - AMG Project One debuts at the Frankfurt Motor Show as the brand's ultimate hypercar. Mercedes-Benz didn’t bother to compete in the hypercar wars when the Ferrari LaFerrari, Porsche 918 Spyder, and McLaren P1 hit the scene.

Integral with this engine is an electric motor/generator that the F1 types call MGU-K (Motor Generator Unit–Kinetic), which is limited to a maximum output of 120 kilowatts, or 161 horsepower. This device must be coupled directly to the engine’s crankshaft upstream of the clutch, but there can be a geartrain involved. With a maximum permitted speed of 50,000 rpm, this ratio is likely around 4 to 1, and by spinning the motor at such high speed, its size and weight can be reduced. A minimum weight of 15.4 pounds is specified for this motor—impressive for its 161-hp output. During braking, the motor serves as a generator to produce electricity to charge the hybrid system’s battery.

Formula 1 engines also have another motor/generator, this one dubbed MGU-H, for Motor Generator Unit–Heat. This motor is coupled to the engine’s single large turbocharger and delivers no torque to the wheels. In the Mercedes, the MGU­-H develops 107 horsepower with a minimum weight of 8.8 pounds and serves two purposes. First, it is used to keep the big turbocharger spinning at high speed to provide instant throttle response with no lag, i.e. anti-lag, without injecting extra fuel and a secondary air injection. Second, it can generate electricity, when the exhaust turbine is producing more power than needed by the compressor. Rather than bypass the excess exhaust flow with a wastegate, the MGU-H absorbs the additional energy to help charge the battery, although a conventional wastegate is still part of the system. On the Mercedes engine, the turbocharger’s compressor and turbine wheels are located on opposite ends of the little engine block, with the MGU-H inserted between them on one long shaft.

Mercedes-Benz Gives the G-Class A Turbocharged Straight-Six Engine

  Mercedes-Benz Gives the G-Class A Turbocharged Straight-Six Engine <p>This is the first time in the US the G-Class has been powered by something other than a V-8.</p>The Mercedes-Benz G-Class has been a staple in the offroading and luxury SUV community since it debuted 38 years ago in Germany. In 2002, the G-Class (or G-Wagen) made it stateside and it has slowly gained popularity. Last year 3,950 G-Wagens were sold and the model continues to gain popularity even though it is uncomfortable and not the best at taking a corner.

But for that price, you get a real Formula 1 engine that revs to 11,00 rpm.

AMG ’s 50th birthday celebrations will culminate in the reveal of the 1,000bhp-plus Project One hypercar at the Frankfurt motor show in September. Project One will use the same hybrid powertrain as the current, all-conquering Mercedes F1 car, with some necessary alterations.

The electricity generated and used by the two electric motors is stored in a lithium-ion battery that weighs, according to the F1 rules, between 44 and 55 pounds. The battery can feed the MGU-K with a maximum of 1.1 kWh per lap, which doesn’t sound like much, but it’s enough to power the 161-hp motor for more than 33 seconds at full power—a very useful power boost on corner exit.

From the Track to the Street

This detailed description of the Mercedes F1 power unit is useful to understanding the Project One road car, because it uses essentially the same unit with a few key differences. First, for the sake of engine longevity, the V-6 engine operates at lower rpm for the street. Based on the Project One’s claimed total power output of about 1000 horsepower, the combustion engine is making about 520 horsepower, which corresponds to a power peak reduced from the race engine’s 11,500 rpm to around 9000 rpm, although the redline is still upward of 10,000 rpm. The street version also idles at around 1000 rpm, down from 4000 in the racer.

1982 Mercedes 300SD Was Painfully Slow

  1982 Mercedes 300SD Was Painfully Slow One-hundred twenty horsepower of diesel fury.In period, Motorweek measured this 120-hp beast as running the quarter-mile in 19.8 seconds with a trap speed of just 68 mph. That performance was actually impressive for a diesel car in the early 1980s - it was the quickest oil-burner Motorweek had tested to date.

Project One . The car is being built to celebrate AMG ’s 50th anniversary and will use a version of Mercedes ’ championship-winning 1.6-liter Formula 1 engine and KERS assistance system.

What Is It? The Project One is Mercedes - AMG ’s effort to bring innovations from Formula One directly to the road. The racing-inspired coupe would use a carbon fiber monocoque.

Second, in addition to the 161-hp MGU-K motor integrated with the engine and driving the rear wheels, the Project One gets two additional 161-hp electric motors to power its front wheels independently. Similar to the 50,000-rpm MGU-K, these motors are geared to the wheels; they can provide greater regenerative braking and capture up to 80 percent of the deceleration energy produced during normal driving. Furthermore, these motors are independently controlled to provide torque vectoring that improves high-speed cornering.

The Project One uses the same type of lithium-ion battery as the F1 car and an upsized version of the racer’s 800-volt electrical system. Keep in mind that with the three electric motors producing a combined 360 kilowatts (483 horsepower), the electrical currents are substantial. Even at 800 volts, the current is at least 450 amps, requiring thick electrical cables. At the 300 to 400 volts used in most hybrids, those cables would be substantially thicker—and heavier.

The battery pack is larger than the F1 car’s as well. Part of this is to help feed the two additional 161-hp motors powering the front wheels. Another reason is to provide greater energy efficiency in normal driving, which doesn’t follow the predictable mixture of essentially full acceleration and full braking seen on a Grand Prix circuit. Finally, the Project One plug-in hybrid has a claimed electric-only range of 15 miles—presumably on some mild, government-mandated driving cycle and not on a racetrack. This battery, which we estimate has a capacity of about 4.0 kWh, is mounted under the car’s front floor, centralizing its 220-pound weight and minimizing the cable lengths required to the various electrical elements.

Mercedes-Benz will unveil the X-Class pickup on July 18

  Mercedes-Benz will unveil the X-Class pickup on July 18 You'll be the fanciest person in the Lowe's parking lot.Late in 2016, Mercedes-Benz previewed its luxury pickup truck with the Concept X-Class. Next week, though, Merc will drop the "concept" and show off the production version.

The two-seater Mercedes - AMG Project ONE will transfer the latest and most efficient Formula 1 hybrid technology almost one to one from the track to the street for the first time. The performance hybrid will produce over 1,000 horsepower at a maximum speed of over 350 km/h.

The Mercedes - AMG Project One will cost €2.275 million plus taxes (.43 million USD) and it’s set for its grand reveal at the Frankfurt Motor Show this Fall. Sales will begin in mid-2018 and production will be extremely limited (275 units in total).

The magic of this plethora of technology is a peak thermal efficiency of more than 40 percent. Mercedes claims that’s higher than any current production engine. Most production engines peak in the mid-30-percent range, and only the most efficient Atkinson-cycle hybrid powerplants even claim 40 percent. For a high-performance powertrain with 1000 horsepower, 40-plus percent is an amazing figure.

Outside the Engine Room

The mid-mounted engine is connected to an eight-speed sequential transaxle from F1 supplier Xtrac that is hydraulically actuated and can be shifted using paddles or allowed to operate automatically.

The car rides on a sophisticated suspension that also borrows Formula 1 design elements. Up front, there are unequal-length control arms, which look to be forged aluminum. Pushrods move rocker arms that feed suspension loads to coil-spring/damper units that are horizontally arrayed across the top of the front subframe. One of these coil-overs acts as a heave-control device, working overtime when both wheels of an axle move in the same direction. Race cars use heave springs to precisely control the ride height and not upset carefully designed aerodynamic elements as downforce builds at speed. The other coil-over regulates body roll. The rear suspension uses multilink geometry with a similar, pushrod-activated dual coil-over setup.

This Sure Looks Like The 2019 Mercedes-AMG GT Black Series Testing At The Nürburgring

  This Sure Looks Like The 2019 Mercedes-AMG GT Black Series Testing At The Nürburgring The 2018 Mercedes-AMG GT R starts at $157,000 and has a 577-horsepower, 4.0-liter V8 inside, going from 0-60 mph in what Mercedes says is 3.5 seconds. That might not even be the end of it for the Mercedes-AMG GT. If you can’t afford a Ferrari, in other words, the GT R is for you, a beast that’s also an alternative to a Porsche 911. Recently, a spy caught some footage of what might be an even fancier model, the GT Black Series, just speeding along at Nürburgring.

The fascinating Project One is making headlines once again as Mercedes released extensive details on the occasion of AMG ’s 50th anniversary festivities prior to the start of the 24-hour Nürburgring endurance race.

Carbon-ceramic brake rotors work with the regenerative braking system to dissipate speed. They’re surrounded by forged-aluminum center-lock wheels with partial carbon-fiber shrouds designed to improve airflow around the tires while still providing some brake-cooling airflow. Contacting the road are bespoke Michelin Pilot Sport Cup 2 tires: 285/35ZR-19s on 10-inch-wide wheels in front and 335/30ZR-20s on 12-inchers in the rear.

Carbon-Fiber Body

The Project One’s body uses F1 construction techniques to produce a completely different shape—a two-seat coupe rather than a single-seat formula car with open wheels and cockpit. It’s a purposeful and highly aerodynamic design, with an aggressive front end, muscular haunches over all four wheels, and an athletic pinched waist. The body is crafted from carbon fiber, forming a lightweight and rigid monocoque structure. In race-car fashion, the engine and transmission serve as structural elements supporting the rear suspension.

When it comes to aerodynamics, the Project One’s design exceeds the rules-restricted Grand Prix car’s. In front are an extending front spoiler and active louvers at the top of the front wheel arches that deploy as needed. In the rear, a prominent shark fin aids stability, a big-time diffuser usefully channels underbody air, and a two-stage extendible wing increases downforce when necessary. There’s also an F1-style air intake above the roof to feed the engine, as well as various ducts to channel air to oil coolers for the engine and transmission.

Could This Be the New Straight-Six AMG CLS?

  Could This Be the New Straight-Six AMG CLS? We heard the company would introduce an mild hybrid turbocharged inline-six in the upcoming CLS sedan. This might be it testing on the Nurburgring.This camouflaged Mercedes test car was spotted on the Nurburgring during industry test pool hours recently. Though the car - which we think might be the new CLS - looks largely the same as the last time we saw it, one thing new does stand out: the sound. A distinct six-cylinder howl can be heard on corner exit. Whether it's this new AMG straight-six or just the 3.0-liter twin-turbo V6 from the AMG 43 engine line, we can't be sure. It could also be a variant of the upcoming AMG GT sedan.

In the Mercedes - AMG Project One , however, extra power will be available for longer and over a wider range of operating parameters. Key to that capability is an 800-volt battery pack with four times the capacity as the one in the Formula 1 car.

Mercedes AMG Project One Offers unadulterated Formula One technology for the road. The new hypercar will thus soon become the first commercially available vehicle with F1 hybrid powertrain and road approval.

Inside the Project One, a fixed pair of bucket seats are integrated into the monocoque, with fine tuning for the driver provided by an adjustable steering wheel and pedals. The design ethos is high-tech minimalist, with little superficial decoration and punctuated by clusters of sophisticated electronic controls. A 10.0-inch digital display serves as the instrument cluster, while a second one near the center of the dash operates the infotainment system. Most controls for operating these displays are in the F1-style steering wheel, which is rectangular and incorporates shift lights in its upper section. Much of the carbon-fiber structure of the monocoque and the doors is gloriously on display, not hidden by upholstery.

Mind-Bending Performance

Mercedes said the Project One has a top speed of more than 217 mph and can accelerate to 124 mph in less than 6.0 seconds. If it delivers on those figures, that acceleration would exceed that of the Bugatti Veyron (zero to 120 mph in 7.2 seconds), the Porsche 918 (the same in 6.7), or any of the other recent hyperexotics that we haven’t tested—in a car with air conditioning, power windows, and the Mercedes COMAND infotainment system.

Production is expected to begin in the second half of 2019 with a run of only 275 cars costing about $2.7 million each. We’d suggest that you start saving now, but at this point, all of the Project Ones are already spoken for.

But Mercedes promises that the Project One’s technology will filter into regular AMG models soon and into mainstream Benzes eventually. One day, there might be a 500-hp S-class in your future, powered by a racing-inspired 1.0-liter hybrid, that gets 40 mpg.

This roof scoop screams Formula 1.We like to call it a road-going Le Mans prototype with a Formula One engine. Indeed, the vehicle will use many full-fledged Formula One technologies, including the hybrid system and the electronics. Judging by that roof scoop, the aerodynamics and air flow optimizations will also be heavily inspired by the world’s most advanced motorsport category.
