2013 is a great year for Volkswagen. Sales are up, even on models that were introduced a few years ago. The Beetle, Passat, Jetta were all reengineered for North American tastes and the switch from Euro-centric designs paid off. Their diesel sales continue capture 40% sales for Sportwagon, Passat, Jetta, and nearly that for Beetle and Touareg.

Next year, model year 2015 which starts in the third quarter of 2014, that's July to most of us, brings a new Golf 7, perhaps the Sirocco which has long been absent from the US, and likely an upgraded GTI as it's based on Golf. We drove those, a few notes follow. But at VW this year the news is all about their new four cylinder engine, the EA888.

The 1.8-liter EA888 replaces a naturally aspirated (no turbo) 2.5-liter five-cylinder that's been a mainstay for a bit too long. The new engine does what any new motor should, bests the old in power, fuel economy and number of applications. Note that a 2.0-liter version is already in use in Jetta GLI and Beetle this year. It makes 210 horsepower. The new third generation EA888 1.8-L, with 184 pound feet of torque–the power you feel–is slated to fill the engine compartment of Jetta and Passat later in the 2014 model year.

The motor features direct injection, as do most new engines. Directly injecting fuel into the combustion chamber allows fine tuning for power, torque, and most important, emissions reduction. The engine is turbocharged with the turbo very closely mated to the engine making throttle response extremely fast. The days of a long wait for power after pressing the accelerator are gone, long gone.

What makes the engine so very interesting to motor heads is that, using integrated software that combines CFD or computational flow dynamics with FEA or finite element analysis. The first models how fluids, air/fuel mixtures and exhaust gasses in this case, flow and bend. FEA permits analysis of how structures can be built to withstand different temperatures, thickness and strength requirements, and generally built with modern casting techniques.

Volkswagen has created an all-aluminum cylinder head that, in one piece, combines the intake manifold, exhaust manifold, and valve train. VW executives, at a recent event in California, said the casting would have been impossible without the integrated software that tied all competing factors together.

That's all well and geeky-good. But what is it like to drive those engines? In a several words, throttle response is instantaneous, noise is nearly absent except for a Teutonic requisite for some engine sound. With either manual or DSG transmissions, power is competitive in its segment. Compared to the outgoing 2.5-L, there is a bit more torque, 7 to be precise at 184 pound feet and identical 170 horsepower. That does not tell the story, however. The torque hits a flat peak at 1500 rpm, "a whopping 2750 revs less than the outgoing 2.5’s torque figure" to quote VW, and it stays flat up to 4750 rpm. That translates to a 0-60 time of 7.3 seconds versus 8.0 for the old motor.

The EA888 gets better fuel economy, according to VW's simulated EPA test cycle. It varies by model, but Jetta with 6-speed manual adds 5 mpg at EPA highway cycle speeds, now 36. City bumps up a mile per gallon with overall 29 compared to 26. Every gallon not purchased helps.

There's more to how the new engine packs more power into a 72 pound lighter package. The crankshaft uses fewer counterbalance weights, for instance, and the new motor features a turbocharger turbine made of higher temperature-resistant alloys (1796F for you number guys), relocated oxygen sensor, billet compressor wheel, electronic wastegate, and that cast head that directs its exhaust gases through the water cooled manifold, shedding up to 160F along the way. That means less wear and tear on the turbo, longer life. Oh, it also means better fuel economy.

We'll await a longer term test to validate the new engines, but an afternoon's driving most of the iterations that will be available convinced us that EA888 is the real deal. Powerful, quick, eager are descriptors that come to mind regardless of the model or transmission. More power, lower emissions, faster engine response, they're all things we like.

Our Euro European Specification signature model testing began with a blue Golf 7 TDI with the new EA288 diesel engine that we don't get until MY 2015.

What was easy to detect, other than a slick-shifting manual transmission and solid new Golf 7 chassis, was improved engine throttle response. Off-idle engine noise was also diminished compared to the current US engine. Specifications are lacking, but we've been told bore spacing is the only thing it shares with the outgoing 2.0-liter diesel. We've also been told EA288 will have 150 horsepower, up 10, and the same 236 pound-feet of torque as the current engine.

As I could feel, throttle response is quicker. Significant changes include a closely coupled exhaust aftertreatment system incorporating a particulate filter and SCR or selective catalytic reduction to meet US emissions standards. That also means a small tank for diesel exhaust fluid or AdBlue in VW speak. We have no information on an expected increase in fuel economy. More than 42? Whoopee!

Electronically set suspension and electronically selected engine maps and response settings, bags of power, and a chassis stiffness that would kill any Michigander; it really wants smooth roads. We hope the new GTI is available untouched, perhaps with a dealer-installed softer option for areas with distressed highways. Or perhaps I didn't explore all the setting options, the plan may only require pushing the button marked "WH" or wretched highways.

Passat.
We haven't seen a Passat in years, and only returned to the VW brand in Europe in 2009. Softer and larger than GTI, and with a different interior, instrument panel and instruments including lighting scheme, seats that resemble Corbeau racing bucket. We weren’t told but assume it uses a 2.0-liter EA888 variant engine, either the 210PS (207 hp) or 256 Ps (252 hp) mated to a DSG. All but base model Sciroccos have adaptive chassis control with three settings (maybe this one was set on soft?). The main feature is a fast-shifting, rev-matching DSG transmission that, on upshifts, snaps out a nasty engine fart that sounds just like a race car. Gut check!
