With its European pedigree and multi-national production chain, Catera was bred to run long on straightaways at autobahn speeds but also move in a predictable manner when traversing a set of curves. It rides on a stiff unibody chassis balanced by a front-mounted engine and tail-loaded differential driving the rear wheels, and contains tractable steering and suspension hardware that allow lively pavement maneuvers.In testing the new Catera Sport, our drive from Paris to the chateau-studded Loire Valley was intended as a leisurely roll through the French countryside. It included high-speed toll roads to skirt Chartres and other urban centers followed by narrow asphalt strips through rolling hills of a rich farmland laced with quaint villages. Yet a tepid pace was not the way our Catera wanted to play those routes. It obviously liked to romp, to run hard on the freeways and chart a smart line through back-road curves, and we were only too eager to comply with the feel and tone of this tight new iteration. Although it's a relatively hefty package (3770 pounds), Catera puts a decisive snap in the throttle. The iron-block engine, fitted with a multi-ram induction system, shows a revised camshaft profile for 2000 models, with new electronic throttle controls. Tinkering with the airflow produced a denser mixture of air and fuel in the cylinders, resulting in more power available across a wider band of torque. Top speed, electronically limited due to tire constraints, extends to 125 mph. Even at the upper limit, the Catera feels entirely stable with the suspension settling nicely in corners and over bumps. It was also surprisingly quiet, reflecting Cadillac's measures to deaden engine noise and streamline the package for better wind management. Shifts were quiet and unobtrusive. The four-speed automatic transmission has electronic controls with adaptive logic to tailor shift patterns to an individual's driving style. Finger buttons on the console let you choose from three shift programs: normal, sport (with aggressive shift patterns that move the shift point to a higher engine speed), and winter (with third-gear start to minimize wheel slippage). Suspension, independent at all corners, adapts continuously to nuances of pavement irregularities and rebounds quickly without harsh action. Components range from MacPherson struts in front with hydraulic control arm bushings to a rear multi-link trailing arm design with automatic load leveling that permits full suspension travel under various loads. The steering mechanism on Catera has power controls in a recirculating-ball design that translates less road shock to the steering wheel and thus imparts a more luxurious sensation to the driver. Steering gear calibrations manage both comfortable low-speed turning and steady force for cruising at speed with an excellent on-center feel. Brakes with a disc at each wheel tied in dual circuits also connect to Bosch ABS/ASR 5.3 anti-lock and traction control systems. A calibration change to the power brake booster brings a more confident feel to the brake pedal. With anti-lock and traction control systems aboard, the Catera's tires rarely slip, even during dicey maneuvers like the tight corner we entered with too much speed that required simultaneous braking and steering to get through the bend. Catera's faster-to-deploy LED brake lights contribute an additional safety factor because they give a trailing driver more time in warning that the driver is braking. When applying brakes at 60 mph, for instance, the quicker flash point works out to more than 17 additional feet of warning distance for a tailing driver.
