Can 4 fewer cylinders make a greater automobile?



  • Pinterest

By lopping off the entrance 4 cylinders and the 243 kilos they weighed, Aston Martin has lowered the DB11’s curb weight to three,880 kilos, shifted the automobile’s stability rearward to 49/51 entrance/rear and introduced the DB11 farther from its luxurious grand tourer roots and nearer to the realm of the sports activities automobile.

Astons have at all times been stunning to take a look at and cozy to drive. These with the V12s had been additionally slightly sooner, extra so in a straight line than round a nook. However I’ve at all times secretly most well-liked the V8s over the V12s. They’re lighter and extra agile and who actually wants all 12 cylinders?

Granted, you get to 62 mph a tenth of a second sooner with the V12, and prime velocity is listed at 200 mph with the 12 versus a mere 187 with the eight. However come on.

As one other nice English sportscar maker allegedly mentioned, “Add lightness.” Precisely how a lot lightness appears to be a matter for dialogue. Have a look at 20 references and also you’ll get 20 solutions for what, precisely, the curb weight is for these two automobiles, as if Aston Martin execs had been kind of making up curb weights every time they spoke to somebody. I used to be advised, and the official press launch claims, that the V8 weighs 3880 kilos. An Aston engineer mentioned that was “moist” curb weight, too, with all of the oil, 90 % of the gasoline and each drop of windshield washer fluid. Some Italian supercar makers checklist “dry” curb weights, which is like weighing in on the fats membership after dehydrating your self for every week in a sauna. The official press launch says the V8 weighs 254 kilos lower than the V12. However our engineer mentioned it was 243 kilos much less. I didn’t convey the scales with me after I drove it. Regardless, the V8 weighs about an eighth of a ton much less.

The 503-hp V8 strikes the stability rearward by two % and lightens the DB11 by 243 kilos whereas giving up 97 hp to the V12.

The brand new engine will not be merely an eight-cylinder model of the V12, both. 5 % of Aston Martin is owned by “technical companion” Mercedes-Benz. So the V8 is AMG’s mighty and venerable twin-turbo four.Zero-liter. It begins as a powerplant shared with the base-model AMG GT and plenty of merchandise with “63” of their titles. Aston Martin then provides its personal consumption, exhaust and air/gas algorithm to it in order that it makes 503 horsepower and 498 lb-ft of torque.

The transmission is similar because the one connected to the Aston Martin V12, a paddle-shifted ZF eight-speed, and the ultimate drive is similar, too. Exterior, the one approach to inform the 2 aside is by counting the hood vents –- 4 on the 12, two on the eight.

So how does it really feel behind the wheel?

Senior dynamics engineer Ian Hartley was requested which he’d take if he had each V12 and V8 DB11s in his storage.

“If I used to be simply going to the outlets I’d take the V12, as a result of you may actually use the larger low-end torque, but when I used to be out for a sporty drive on good roads I’d take the V8.”

Sadly, there have been no outlets on the day of our drive. Fortunately, there have been many good roads. The one disadvantage was that Aston had us pair up for the drive, and the co-pilot I wound up with, an expensive pal we’re at all times glad to see, may need greater than canceled out the 243-or-so kilos of weight financial savings. This was a bit odd, contemplating the entire level of the drive was to indicate how a lot better the V8 is with 243 fewer kilos after which they add about that a lot in passenger. How am I presupposed to know?

So let’s take a look at the maths: a 3880-pound automobile with 503 hp has a ratio of seven.7 kilos per hp. Assuming the V12 weighs 4123 kilos and has 600 hp, the quantity is 6.9. So the V12 must be higher, proper?

Not essentially. This may occasionally have been purely hallucinatory, however I swear the V8 DB11 felt lighter immediately, passenger or no. Not simply the throw-weight of the automobile, however the truth that it’s just a bit higher balanced. With the load off the nostril, the steering is lighter and feels faster. Begin cranking the wheel and the entrance finish swings into line only a bit extra quickly than the V12 I had pushed solely weeks earlier than (thanks, Aston Martin).

After tiptoeing my well beyond many bicyclists, to whom I at all times give at the least three ft and attempt to give extra, I used to be on an empty highway with nothing on it and had an opportunity to fling the V8 about. I attempted all three Dynamic modes out there: GT, sport and sport plus. These changes “…progressively intensify the response of the engine, transmission, electrical energy steering, torque vectoring by braking, and firmness of the adaptive damping.” As is commonly the case, it solely felt proper in GT mode. Cranking it as much as sport or sport plus simply made every little thing really feel overboosted and sensitive. That is significantly so on AMGs, in my view, however is commonly the case with different automobiles. I say set it up proper one time and depart it alone.

In a straight line, acceleration is spectacular. With solely a tenth of a second separating the Vs Eight and 12, you could not want these additional 4 cylinders for many stoplight drag racing conditions. I didn’t discover as a lot turbo lag as some have complained about. And the sound is pleasant with out being intrusive, a lot better than the higher-pitched cracking exhaust of this engine in an AMG.

So which to decide on? I’d agree with Engineer Hartley and selected the V8. The DB11 V8 remains to be within the class of luxurious GT, however it fills that function very effectively. And it prices $17,500 lower than its V12 sibling, as if that issues to anybody at this higher finish of the stratosphere.
