In Case 600 Horsepower Isn’t Good Enough, how does 800 horsepower sound?

German tuner G-Power is known for building programs that turn sporty vehicles into performance savants on four wheels. It’s worked its magic on a handful of BMWs over the years, but now, it’s turning its attention to Mercedes-AMG, specifically the German automaker’s powerhouse wagon, the E 63 S Wagon. At the core of G-Power’s new tuning program for the E 63 S is an engine upgrade that’s sure to rock the socks of owners who are crazy enough to get the kit. The program is definitely not for everyone, least of all those who are more than happy with having over 600 horsepower to play with. But, for the rare few who think that 600 ponies isn’t good enough, this new kit from G-Power should be right up your wheelhouse.

There are no fancy aesthetic add-ons and very little aerodynamic upgrades to speak of

You’re not getting anything cute from G-Power. The tuner is as in-your-face as it gets, and this program, well, it’s going to smash you in the face if you’re not careful. G-Power doesn’t get cute in dressing up the AMG E 63 S. There are no fancy aesthetic add-ons and very little aerodynamic upgrades to speak of. Ok, so the tuner did give the performance wagon a new set of 20-inch Hurricane wheels and wrapped them up in 245/30 ZR20 and 285/25 ZR20 tires in the front and rear, respectively. You’ll have to pay €6,681 for the wheel-and-tire combo, and if you convert that into Benjamins, that looks like a little over $7,600 of your hard-earned money.

It’s safe to say, though, that the new wheels and tires are just the appetizers to the main course. At the heart of G-Power’s program for the Mercedes-AMG E 63 S is a tuning program that pushes the credentials of the performance wagon into full-fledged supercar territory. The tuner’s very own “35th Anniversary Edition” Performance Software V1 system is largely responsible for the massive increase in power, but it is supplemented by modified turbochargers, new stainless steel downpipes, and a stainless steel exhaust. It’s not much of a program in terms of quantity, but when has G-Power blinded our sensibilities with quantity? This kit is, straight and pure, all about the quality that comes with the German tuner’s aftermarket expertise.

The Mercedes-AMG E 63 S raises its output from just over 600 horsepower and 627 pound-feet of torque to a staggering 800 horsepower and 737 pound-feet of torque

Put all the changes in place, and the results are astounding. The Mercedes-AMG E 63 S raises its output from just over 600 horsepower and 627 pound-feet of torque to a staggering 800 horsepower and 737 pound-feet of torque. Do the math, and you’re looking at an increase of almost 200 horsepower and 110 pound-feet of torque, which is already the output you get from an entry-level sports car. The massive increase in power manifests itself in the power-packed wagon’s performance times. The super wagon — we can call it that now, can’t we? — can now accelerate from 0 to 62 mph in just 3.1 seconds, 0.3 seconds quicker than the standard model. If that isn’t enough, the wagon’s top speed limiter has also been removed, giving it the freedom to stretch its legs to the tune of a 211-mph top speed. That’s right in the vicinity of what the Ferraris, Lamborghinis, and McLarens of the world can do.

Needless to say, you’re going to have to spend big to own big. The full kit offered by G-Power can set you back around €20,000. That’s almost $23,000 in tuning upgrades alone. Combine that with the $106,950 starting price of the AMG E 63 S, and you’re looking at costs that could reach $130,000. It’s probably not the smartest way to spend that kind of money — who really needs an 800-horsepower station wagon when you already have a 600-horsepower one? — but who needs common sense when you have a wagon that can go as fast as some of the finest British and Italian supercars in the world?

If anything, $130,000 is a cheap price to pay to get a completely uninhibited version of the Mercedes-AMG E 63 S.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio

A spacious station wagon with plenty of room for family and spare time, or a powerful sports car? Or to put it another way: reason or fun? Automobile enthusiasts are forced to make this decision again and again, and yet it is actually unnecessary. After all, there are various models from AMG, for instance, that offer both. Such as the E 63 S from the 212 series with a 585-HP and 800-Nm twin-turbo V8, which still has more than enough room for five passengers and their luggage.

For all the high speed junkies who want even more power than these eight cylinders deliver, G-POWER now has just the right solution. The specialists from Aresing in Upper Bavaria are eminently skilled at using software and hardware optimizations to give a boost to the performance of vehicles whose standard models come off the line with quite a bit of power. For instance, they enable the Mercedes-Benz E 63 S AMG to achieve an impressive 800 HP / 588 kW and 1,000 Nm!

Key Facts: G-POWER E 63 S AMG (S212)

• 800 HP / 588 kW at 5,500 rpm (+215 HP / 158 kW)

• 1,000 Nm at 4,000 rpm (+200 Nm)

• Top speed: > 340 km/h

• 0-100 km/h: 3.1 s (4Matic)

• G-POWER Performance Software V1 “35th Anniversary EDITION”: 2,437.00 euros




• Top speed increase “35th Anniversary EDITION”: 434.00 euros

• Set of 20” G-POWER HURRICANE RR forged wheels, incl. 245/30 ZR20 and 285/25 ZR20 tires: from 6,681.00 euros

Compared to the standard series models, this means adding a juicy 215 HP / 158 kW and 200 Nm of torque. One of the factors responsible for this is the G-POWER Performance Software V1, which is available during the anniversary year of 2018 at a reduced price of 2,437 euros for the “35th Anniversary EDITION”. When developing this software, G-POWER paid attention to keeping it perfectly compatible with the engine, of course, so as not to put too much strain on the engine. What is more, all protection and diagnostic functions have been retained. A top speed increase – costing only 434 euros in the “35th Anniversary EDITION” – has also been added to the V1 performance software. So you save 35 percent off the normal price in both cases.

The software optimizations are combined with several adjustments to the engine hardware: thanks to extensive modifications (5,000 euros) the two turbochargers have now been made considerably more powerful by using aerodynamically optimized turbine wheels and CNC machined housings. To these are added a stainless steel exhaust system (3,866 euros) connected to the power train with downpipes that are also stainless steel (2,240 euros).

All in all, the optimizations let the E 63 station wagon reach 100 km/h in only 3.1 seconds. The top speed can even outstrip 340 km/h! These figures are certain to put it on the same footing with elite super sports cars.

And finally, the G-POWER E 63 S AMG also visibly demonstrates that it is not merely your commonplace AMG. This is due primarily to the new set of wheels. The wheels spinning under the fenders are own-brand HURRICANE RR wheels. These 20” forged wheels with five classic double spokes sport high-performance 245/30 ZR20 and 285/25 ZR20 tires. The full set of wheels costs 6,681 euros.
