Construction workers working to the left, 
Ferrari dealer to the right. Real, actual bustle. Barcelona does not act like  the rest of Spain, which is probably why it has two cell phones and is  maybe "going out with the girls" on Friday night.
Just a few hours earlier, we'd been wedged in the fab city's underbelly,  parked below ground level opposite Casa Battlo, the fab apartment  building rendered edibly by Antonin Gaudi in melted stucco, so that no  stock Pella window would fit. One by one, we woke up a fleet of 
2014 Mercedes-Benz E63 AMGs one by one, wagons, sedans, oops that's a SEAT, and blew off some  morning cobwebs that had caught some of us up too early after being up  too late. 
And then about five hours later, we were detained. Not that kind of detained--the other kind. With handcuffs.
Let's just say we're not 100 percent against the idea, but at the day's start, this is not how we were supposed to roll.
The way in which we were to roll was to go like this: blast down Las  Ramblas, hit a main artery, ride the spurt out to the Catalan hills  northeast of town, to an awesomely drawn stretch on an unfamiliar map  that could have doubled for Latigo Canyon Road. On the navigation  system, it was Muntanya Montserrat, and quickly we figured out every  country must have one, since the last Montserrat we visited currently  sits under a dozen feet of volcanic ash. This also was not in the plan.
Good thing that about three-quarters of the real plan came through  before we descended out of Montserrat's piney  better-than-California-ness. (San Diego--you've been warned.) It'd be  the only shot we had at shoving this E63 AMG sedan around steeply  inclined, frequently elbowed roads without so many officials in the mix.
And the E63 AMG requires a fresh set of hands and hocks this year,  because it's changed once more--thrice now if you're using that word,  and counting all the times since the E-Class was completely new in 2010.  Every other E-Class is eking out fuel-economy gains wherever it  can--the diesels are dropping cylinders, the V-8s are tapping out for  twin-turbo sixes. The AMGs are content to sail by with a curt little  wave. Tschuss! This year, they're up from 518 hp to 550 hp and 531  pound-feet of torque in base form, and if you spec up to the "S"  model--a new sub-sub-model in the hierarchy--you'll net out at 577 hp,  590 lb-ft of torque.
Whatever you choose, Lord, a scalding-hot 0-60 mph time of under 3.6  seconds is yours for the taking through RACESTART launch control. Top  speed: it's 155 mph on the E63 AMG sedan, 186 mph on the E63 AMG S sedan  and wagon.
Burble and speak
Oh, that engine. The 5.5-liter, twin-turbo V-8 might always be seen and  heard as the pale successor to SLS' 6.2-liter V-8--the one that  energetically whomp-bomp-aloo-bomps through tunnels while it drinks  liters of 93 blend. We think it's an unintentional parody of Little  Richard's perfect day. That's cheating the twin-turbo unit its due,  though. The newer engine climbs a Matterhorn of torque from 1750 to 5000  rpm, feeling rich and sounding in top vocal form all its own, and less  manic about, well, everything.
The seven-speed automatic that's permeated the AMG and 
Mercedes lineups is present and accounted for, with the usual comfort, sport,  sport-plus, and manual modes. Stop/start is here too, and it's not the  fig leaf you'd think, even if it starts the 
E63 AMG in second gear when the tranny's in comfort/economy mode and thwaps the  drivetrain to life with a mini-riding crop. The EPA gives it some  credibility for saving gas--all of which goes away when you remap things  to any of the more adventurous modes. Here it's set to stun: start/stop  is disabled, shifts speed up and get rev-matching on the downshift. The  exhaust opens up like bronchioles on a good hit off an inhaler, and  launch control comes online for perfect 0-whatever-mph runs.
That the E63 comes with all-wheel drive as standard equipment this year,  is a mild controversy among the AMG crowd. The third AMG to get  all-wheel traction after ML and CLS, the E63 AMG has a torque split of  33:67. You can give it the slip--but the E63 AMG S gets a limited-slip  differential to avoid just that potential for uneven wheelspin. Plus it  also gets lovely red brake calipers, and optional carbon-ceramic brakes  that replace the 14.2-inch vented and drilled discs that otherwise hide  behind the E63's 19-inch wheels.
Finally, when it comes to describing what the E63 looks like without its  overgarments, there's an adaptive suspension poised for Montserrat's  loopy landscape with comfort, sport, or sport-plus modes. It's not a  fully adaptive setup--AMGs carry steel suspension bits in front with  conventional shocks, it's the back that gets air springs--and as a  result, on purpose, the E63's never going to be as soft as a base  E-Class. Or as quiet. The firm thump of the tires comes to life through  the steering wheel with the barest of nudges--the electric steering rack  builds up plenty of its own resistance a few millimeters off  center--and the cabin's always filled with the ripe, mature sound of a  big V-8 barking out orders like it's in charge. That's life with an AMG.  Either you're in, or you're out.
You don't go halfway with the E63 in anything. It's a big sedan--bigger  than ever, heavier than ever--and all-wheel-drive and electric steering  have put more lead in its sled, more perceptually than physically (the  AWD setup adds only about 150 pounds.) The E-Class' long wheelbase and  the weight dialed into the steering, even in the lightest setting,  aren't neutralized entirely by the rear torque bias. Carving up  Latigo--sorry, Montserrat's canyon road--can be a task, even with a  brake clamping on an inside rear wheel, vectoring it in more closely to  the corner. It's just grown into a massively powerful, unbelievably  stable machine that's serene and unflappable through 30-mph sweeps, and a  real maul on 15-mph door-scrapers. Flip the paddles low once you're in  manual-shift mode and you'll be able to slide your way out with brute  force. In any other driving scenario, just open it up. It'll suture  itself back to the ground, one way or the other.
