Most car buyers are happy to put the days of crank windows, cassette decks and cold buns behind them (pun intended), but the growing complexity and volume of new in-vehicle technology can be as much a curse as a blessing (i-Drive, we’re talking to you).

Ward’s editors collectively test drive about 100 new vehicles each year, giving them an informed perspective when it comes to the latest-and-greatest whizz-bang features. With technologies once reserved for premium cars now showing up on volume vehicles, it’s time for some ranting and raving: “Exactly what does that one do?”

Technology: Electric Power Steering

What’s to Love: If any technology promises to put auto makers on the straight and narrow path to regulatory compliance without compromising customer satisfaction, it’s electric power steering. More likely, EPS, finally flooding the market, will enrich the driving experience.

Consider the European-market Fiat 500. It features a button that can transform steering-wheel feel from relaxed (for rush-hour Rome) to tight and sporty (for traversing Southern California’s Topanga Canyon Loop).

Outlook: Ford has said all of its models will feature EPS by 2013. Other OEMs won’t exactly be standing still. Do the math.

Technology: Smartphone “apps”

What’s to Love: Face it, we’re all control freaks, some more than others, hence, the smartphone proliferation. And with each passing day, another app arrives to link man and machine. OnStar promises charge-status updates for the Chevy Volt extended-range electric vehicle. And (maybe) text messages that warn of low tire pressure.

Now, Faurecia trumpets the prospect of an app that automatically adjusts a vehicle’s seats to conform to the most ergonomic position for each occupant.

Outlook: The sky is the limit. Especially if wireless plans come down in cost. OK, so maybe we’re in for a slow rollout.

Christie Schweinsberg

Technology:Eco pedal

What’s to Love: Optional in the new Infiniti M37 and M56 sedans, Eco pedal goes a step further than the now-ubiquitous gauge-cluster eco light to induce fuel-efficient driving by governing how much pressure can be applied to the accelerator.

Get too aggressive and the pedal resists/pushes back. “No rubber-burning for you!” we imagine the Soup Nazi scolding lead foots who just can’t help themselves.

Outlook: Despite the whines of some Ward’s editors, my jaunt in a V-8 M56 with Eco pedal this year yielded an unbelievable 28.2 mpg (8.3 L/100 km) at mid-range speeds. Expect this technology to spread to other auto makers and lower-priced models, especially as new CAFE rules loom.

Technology: Optima’s heated steering wheel

What’s to Love: Warm hands for the masses. Not new but still rare compared with the proliferation of “bun warmers,” Kia Motors America is breaking the mold by bringing the heated steering wheel into the non-luxury realm.

Kia’s new ’11 Optima offers the technology as an option on the EX Turbo grade’s premium package. Cold hands on a frosty Midwestern morning say, “Thank you, Kia.”

Outlook: The competition won’t tolerate this one-upping for long.

Drew Winter

Technology: HMI touchpad on ’11 Audi A8.

What’s to Love: User-friendly in any language. The idea of creating a centralized controller for hundreds of vehicle functions with a simple device has kept designers and electronics engineers up late for more than a decade.

Now this task is complicated further by growing luxury markets in China, Russia and other countries that do not use the Western alphabet.

Audi’s new MMI (man-machine interface) touchpad demonstrates a truly global approach to connecting drivers with electronic functions. It recognizes handwritten letters and numbers for navigation destinations in many languages, including Cyrillic, Chinese, Cantonese, Korean and Japanese characters.

Outlook: Available now only on the pricey A8, marketplace acceptance will determine whether it follows the glide path of the iPod or the Betamax.

Technology: FMVSS 202a-compliant fixed head restraints

What’s to Loathe: Literally a pain in the neck. Since 2008, Federal Motor Vehicle Safety Standard 202a has mandated that all vehicles must have front seats with head restraints that reduce the potential for whiplash.

Nothing wrong with improving safety, but clearly there is a right and a wrong way to meet the requirement. Too many of the ’11 models we tested this year have bulky, forward-leaning head restraints that make it impossible to get comfortable in our seat. There’s got to be a better way.

Outlook: Hopefully, a combination of consumer complaints and improved seating technologies will allow this government regulation to be less intrusive in the future.

Byron Pope

Technology: Automatic-parking systems

What’s to Love: Takes the pain out of parking. Ford, as well as Toyota’s Lexus brand, offer a form of this technology, which guides motorists through the parallel-parking process. Though not difficult for some drivers, many consider parallel parking akin to docking the space shuttle at the International Space Station.

Outlook: These systems are more than just a nifty trick to show off to your friends, actually serving a practical purpose.

Technology: Mode selectors

What to Loathe: Auto makers increasingly are offering mode selectors that allow drivers to alter vehicle systems by selecting from options such as “econ” or “sport” modes. In theory, it’s a good idea, but often one mode is pretty much indistinguishable from another.

Outlook: Some auto makers have developed systems that allow you to effect notable changes in the car’s setup. But the most have not, making this a technology most motorists can do without. At least for now.

Tom Murphy

Technology: Lane Departure Warning

What’s to Loathe: Fast becoming standard equipment on many luxury vehicles, LDW is intended to alert wayward drivers. But in reality it’s unnecessary and annoying, an electronic security blanket for drivers who will consider it safe to multitask to an even greater extent. Yes, the technology works, but it can’t correct for stupidity.

Outlook: It’ll go away as soon as an auto maker is sued by someone who caused a fatal accident while texting, arguing that LDW didn’t do its job.

Technology: Forced Induction

What’s to Love: Whether it’s turbocharging or supercharging, an internal-combustion engine is just plain better with added boost, making any vehicle more fun to drive. Latest-generation turbochargers and superchargers are more efficient than in the past, enabling engine downsizing while improving mileage.

Outlook: Of last year’s Ward’s 10 Best Engines’ winners, five were turbocharged, one was supercharged. The moral of the story: Forced induction is here to stay.

Dave Zoia

Technology: Cruze’s Smart Grille

What’s to Love: On Chevy Cruze Eco models, the lower front grille closes at higher speeds, allowing the air to flow around the body more efficiently, contributing to the car’s 10% fuel-economy gain over the standard sedan. It’s a clever trick made possible by the growing sophistication of electronic controls.

Outlook:Other models, including the ʼ12 Ford Focus, will offer similar systems. Look for the feature to proliferate in the quest to optimize aerodynamics in the run up to 60-mpg (3.9-L/100 km) fuel-economy standards.

Technology: Corvette’s Carbon-Fiber Sunblock

What’s to Love: A carbon-fiber body panel with the high-tech look of – ta-da – carbon fiber. That’s made possible on the ZR1 Corvette by a new ultraviolet-resistant clear-coat material General Motors engineers developed to protect carbon fiber from the sun.

Previously, designers were forced to go with painted carbon-fiber body parts or use other more durable materials to achieve a faux carbon-fiber look. The ZR1 features the exposed-weave carbon fiber material for its roof panel, roof bow, rocker moldings, front fascia splitter and the underside of the hood.

Outlook: Limited. May find a home with more sports cars, but don’t look for it in a next-gen Honda Accord or Chevy Malibu.

James Amend

Technology: Buick Regal GS’s interactive driver control

What’s to Love: Three distinct settings, ranging from Sunday afternoon “Touring” to “GS,” where sophisticated electronics dial up a drum-tight suspension, wickedly-fast steering response and a lively throttle.

While not new to the industry, it’s a first for GM. As standard equipment on the ’12 Regal GS coming late next year, the technology should perfectly complement the car’s 2.0L turbocharged 4-cyl. engine making 255 hp and 295 lb.-ft. (400 Nm) of torque. Just point us to the nearest road course, please.

Outlook: The Regal GS gets a 6-speed manual because its champion, former GM product-boss Bob Lutz, says a high-performance sports sedan cannot be taken seriously without one. The same goes for selectable driver settings, standard equipment on the best products out of Germany. It will give Buick the technical credibility it needs.

Technology:eAssist on Buick LaCrosse

What’s to Love: How about 37 mpg (6.4 L/100 km) on the highway in a large luxury sedan? The '12 LaCrosse with eAssist also will deliver 25 mpg (9.4 L/100 km) in the city cycle. The technology is GM’s next-generation belt-alternator-starter system, a mild-hybrid application mating an electric motor/generator to the auto maker’s award-winning 2.4L gasoline direct injection engine.

A 115V lithium-ion battery provides power. The BAS system smoothes out takeoffs from the start/stop system and also provides a boost during passing maneuvers or climbing a long grade. Aside from stopping at the pump less often, the experience is supposed to be transparent. However, we suspect it will give the 4-banger the extra punch it could use in this application.

Outlook: GM makes eAssist standard equipment on every base model LaCrosse with the 2.4L engine and prices it the same as models with a more-powerful 3.6L V-6. It will provide an interesting glimpse into whether Americans truly are willing to pay for fuel-saving technology. The auto maker insists eAssist will proliferate across its portfolio.
