No car is perfect. but there are dozens of perfectly ingenious technologies integrated into various models, ranging from incremental improvements of existing features to complete reinventions of what it means to drive. What if I, a humble auto writer, could cobble them together to create the ultimate car?

For the past year, I’ve been keeping track of the coolest, most mind-blowing innovations in the auto industry. Going over my notes, I discovered that they are without exception German, as if they’d been dreamed up by some mad scientist in a decaying Bavarian castle overlooking the Autobahn. Whatever the bauble, doodad, or feat of engineering — no matter how simple or complex — everything Teutonic seemed the most intuitive, or looked the most gorgeous, or drove with that most supreme harmony of sportiness and luxury.

Together, I realized, these items comprise at least the rudiments of my perfect beast, my own personal Frankencar. So raise a stein of doppelbock and toast my creation. It’s ALIIIIIVE!

VW Touareg Side Scan: Some cars sound an alarm when crossing out of a lane, an electronic minder I find so annoying I always turn it off. But the Touareg features a truly valuable blind-spot detection system: Radar tracks the area to the side and behind, and a lamp in the side-view mirrors lights up in warning if you’re about to smash that Smart car running in your blind spot.

VW Touareg ABSplus: In an emergency stopping situation in snow, most cars actually brake more slowly with ABS* than without it — the pulsing of the brakes keeps snow, ice, and dirt from accumulating in front of the front tires, which would add friction and enable the car to stop more rapidly. ABSplus, Volkswagen’s patented automatic surface detection system, reduces braking distances by up to 20 percent on loose ground by allowing more complete brake lockup, but still works like normal ABS when the driver brakes more gently. (NOTE: ABS was actually a Mercedes innovation – it was the first carmaker to bring the technology to the market. Learn something new every day.)

Mercedes-Benz ML PreSafe: Mercedes’ Pre-Safe technology might actually be a lifesaver — if the system detects a pending crash it instantly moves occupied seats backward or forward to line up with the airbags, snugs the seatbelts, and even closes all the windows. A separate system also helps you brake harder in an emergency, which could enable you to avoid an accident in the first place.

BMW 3 Series USB-audio interface: Lots of cars offer iPod connection options these days, and I’ve tried most of them. But only the BMW’s seems fully intuitive, employing the same organizational structure found on your iPod. The radio’s face displays track information, and simple-to-use controls allow you to manage functions like playback, volume, skip, and shuffle. The system even “remembers” up to four iPods and their databases, so you can access your music without the lag that plagues other in-car systems.

Mercedes-Benz CL550 LCD-analog gauge: It’s counterintuitive, but the speedometer in the CL550 is both digital and analog. It’s an LCD screen (think laptop) that displays a classic round speedometer as well as other details, such as the gear you’re in, the upcoming turn on the navigation system, or the current radio station or iPod track. It’s safe, yes — you can quickly glimpse important information while keeping your eyes on the road — but even cooler is the subtle white-and-brown readout, which is practical and luxurious all at once.

Mercedes-Benz CL550 Night View Assist: Night-vision systems have, until now, been a distraction at best. But Night View Assist is just plain stunning: The in-dash LCD screen dissolves from its gauge functions (though the speedometer simply converts from a dial to a bar graph) into an infrared view that far outdistances the reach of even the car’s high beams. It seems gimmicky, but it works; on a recent foggy night the screen showed a man stumbling along the road long before the headlights picked him up — and he was weaving as if he were drunk, so I’m glad I had the extra time to avoid him.

BMW 335i Active Steering: BMW’s nifty Active Steering function reduces the number of steering-wheel rotations required to turn the car at slow speeds —when parallel parking, say, when you’d ordinarily be wrestling the wheel like a sailor in heavy seas — and also makes the steering less sharp at high speeds, when too much sensitivity would be annoying and dangerous. It sounds odd, but once you try it you’ll wonder why every car doesn’t have Active Steering.

BMW 335d Twin-Turbo Diesel: Americans’ long-held bias that diesels are slow and stinky may be dying hard, but in reality new-tech diesels not only burn clean, some are scary fast. The 335d hits its torque peak — 425 foot-pounds — just off idle speed at 1,750 rpm. Acceleration is seriously brisk because all that force is so readily available, thanks to twin turbos — one that gets the engine turning at low rpm, and the main one that engages once the car is moving at speed. And fuel economy is about 30 percent better than that of the gas-burning 335i.
