Toyota asks the question, "What is a suitable sports car for the 21st Century?"

At the North American International Auto Show in Detroit, Michigan, which begins tomorrow, Toyota will debut a hybrid-electric sports car combining high-output drivetrain performance with ultra-low emissions and exemplary fuel efficiency. Thanks to a 3.5-liter V6 gasoline engine and a "sports hybrid system," the rear-wheel-drive Toyota FT-HS is projected to develop 400 horsepower good for zero to 60 mile-per-hour runs in the four second range.

Several aerodynamic and weight saving measures have been employed to improve performance and efficiency. Sharply designed "Aero-Corners" lessen turbulence and optimize airflow. The "scooped-out" roof maximizes passenger headroom while reducing aerodynamic drag. That roof panel is made of carbon fiber Kevlar and is capable of retracting into the rear seat area to allow open top cruising. A speed-senstive rear wing and carbon fiber diffuser precisely direct air out back to maintain stability. Throughout the car, body material has been removed around critical components to reduce mass but maintain functionality. Massive 21-inch carbon fiber wheels reside in 245/35-series front and 285/30-series rear tires.

"Drivers today are not satisfied with cars that are simply fast," said Kevin Hunter, vice president of Calty Design Research, Toyota's Newport Beach, California design center. "In addition to driving enjoyment, today's drivers are concerned about safety, ecology and social responsibility."

Analysis: While true that many vehicle buyers now demand cleanliness and safety in addition to performance, FT-HS fans will likely appreciate the concept for its technological advancement above anything else. Features such as Kevlar roofing and carbon fiber wheels are the type of novel automotive approaches that render this Toyota prototype interesting and unique to tech-savvy car buffs.

Brabus improves upon “Fastest Sedan in the World” performance

Brabus, the German tuning company specializing in Mercedes-Benz vehicles, has bested its own top speed record, redefining the performance threshold for its “Fastest Sedan in the World” modified Mercedes CLS500. An October racetrack run in Nardo, Italy topped out at 227.23 miles per hour, eclipsing the 225.18 mph "jaunt" achieved this past summer.

The “Brabus Rocket” is based on the smoothly-styled Mercedes CLS “four-door coupe,” a relatively new model in the Benz lineup. Thrust is sourced from a twin turbocharged V12 engine displacing 6.3-liters. Output is a staggering 730 horsepower and 974 foot-pounds of torque, although twist is limited electronically to a still gargantuan 811 ft-lbs. A modified five-speed automatic transmission and locking rear differential assume the task of transferring the available power to the pavement.

Upgraded brakes and suspension components have been included to harness the powertrain’s potential. Brabus collaborated with Bilstein in developing the height-adjustable coil-over suspension with six shock absorber rebound settings. Huge 14.8-inch front ceramic disc brakes are clamped by 12-piston aluminum calipers. At the rear, 14-inch steel discs turn inside six-piston binders. Well-proportioned 19-inch wheels are wrapped in 255/35-series front and 285/30-series rear tires. Aerodynamic body touches front and rear assure the Brabus Rocket remains planted at top velocities.

Analysis: The benefit of extracting another 2 mph out of the Brabus beast is one that will be felt by the company tuners only. Customers who pay the 348,000-Euro (over $446,000) premium are still limited to 217 mph (350 kilometers per hour). Still, what fun is the car if its full performance potential is never realized?

Formula One Ferrari pit stops demonstrate life-saving precision

Formula One racing, as identified by the Federation Internationale de l’Automobile (FIA), is the top class of sanctioned automotive racing in the world. Eleven teams competed in the 2006 season, which included 18 Grand Prix races. With vehicle speeds well beyond 200 miles-per-hour, engines surpassing 20,000 revolutions per minute, neck-jarring cornering g-forces and ultra-refined handling, the drivers depend on precise specifications to avert disaster. Miss a critical point and face the horrendous consequences.

Similarly, surgeons encounter highly exacting standards in executing the tasks of their profession. Not only do complex procedures themselves require perfect accuracy, but the post-operation period afterward demands flawless technique. Misfile paperwork, engage the wrong equipment or delay a patient transfer and deal with the severe results.

According to a recent Wall Street Journal article, one British hospital has turned to motor sports in an effort to reduce patient complications due to faulty procedure. Led by pediatric intensive care chief Allan Goldman, the Great Ormond Street Hospital in London commissioned Ferrari’s Formula One team to help improve the hospital’s method of transferring patients, or the “handoffs” that occur when a patient is moved from one unit to another or from one shift of staff to the next. A study conducted in 2005 revealed that approximately 70 percent of preventable hospital mistakes occur due to communication errors, and about half of mishaps take place during handoffs.

The connection with car racing came about serendipitously. During a Sunday in 2003, Dr. Goldman and Dr. Martin Elliot, a surgeon, sat down to watch the Formula One race on television after a difficult week. They noticed that the pit stops - the quick periods during which tires are switched, fuel added, aerodynamic body panels adjusted and air vents cleaned – were remarkably similar to patient transfers in the hospital. But whereas pit stops occurred seamlessly in just seconds, hospital handoffs happened slowly and often chaotically.

Intrigued, the two doctors contacted members of McLaren, a manufacturer that fields an F1 car. The team of racers demonstrated the need to eliminate small errors rather than concentrating exclusively on large ones. Previously, a surgeon named Marc de Leval at Great Ormond had postulated in a published paper that minor “human factors,” not major procedural failures, accounted for many complications during and after surgery.

When Dr. de Leval heard the McLaren team’s presentation he contacted Ken Catchpole, a human-factors expert, for further research. Eventually in 2005, Catchpole, Dr. Elliot and Dr. Goldman visited with Nigel Stepney, Ferrari's racing team technical director, in Maranello, Italy. After viewing videotape of Great Ormond’s handoff procedure, Stepney was struck by how “clumsy and informal” the task appeared.

Pit stops often occur in silence, as team members execute their assigned tasks and are clearly aware of leadership designations. But in the Great Ormond Street Hospital, doctors and nurses would carry on multiple conversations without always knowing who was in charge. There was also little foresight at the hospital, as complications would only be addressed after a situation arose. In racing, Ferrari always had contingencies in place should a circumstance require immediate adjustment.

Armed with their newfound knowledge, Dr. Goldman, Dr. Elliot and their colleagues began implementing policy inspired by Ferrari pit stops. A seven-page protocol was formulated outlining patient handoff procedures. From December of 2003 to December 2005, studies of patient transfers were completed to determine the effectiveness of the program. The results were encouraging. Based on 50 instances – 23 before the Ferrari technique and 27 after – technical errors per patient transfer declined 42 percent while information omissions dropped 49 percent.

Some doctors were hesitant to adopt the program, believing the old method to be sufficient. Dr. Goldman also stopped short of placing hospital teammates in pre-determined positions around patients, allowing some flexibility in execution. As implemented, however, the technique was clearly beneficial.
