seen from outside the vehicle, a change from 16- to 17-inch standard wheels and tires. The S is now fitted with standard 18-inch rims, while 19s (18s and 19s on the base) are now optional across the line. Depending on the wheel tire combination the track has also been widened, up to 35 mm (1.4 in) at its widest. Components have also been strengthened, with the wheel bearings, as an example, stiffer on 2005 cars. The chassis also features weight savings, with new hollow castings in the front wheel support and new aluminum castings in the rear axle subframe. Actually, pretty well every component of every system has been improved, with the 2005 Boxster's recalibrated rack and pinion steering system delivering fewer turns lock to lock, adjustable steering wheel height to 40 mm (1.6 in), and aluminum and magnesium construction for better weight optimization, all contributing

to a car even more agile than the 2004 Boxster which was already on most automotive critics' short list. Along with the new car's explosive acceleration, comes one of the sweetest shifting 5- and 6-speed transmissions in the business. Actually, for the first time in my experience testing cars the completely new 6-speed shifts smoother than the modified 5-speed. This isn't the case when upgrading from the Audi A4, for instance, which offers a delectably smooth shifting 5-speed with its base 4-cylinder car and a rather notchy 6-speed in top-tier trim. The Boxster's is wonderful in either trim level, but the 6-speed is truly delightful, snapping from gear to gear without even the need for conscious thought. What makes the difference? Porsche engineers made a variety of refinements such as higher load synchros and modified ratios, but finishing each transmission off is a 26 percent shift path reduction in the case of the 5-speed, resulting in shorter throws, while the 6-speed received a 15 percent reduction.
