The 2011 Regal – The US version of Insignia image

On Thursday Buick will reveal the 2011 Regal sport sedan to customers in the L.A. area.

The new Regal arrives in the second quarter of 2010, with its sights aimed squarely on competitors like the Acura TSX and Volvo S60. It has a longer wheelbase and greater trunk volume than those vehicles, along with standard features – including a six-speed automatic transmission, 18-inch wheels and OnStar.
The Regal’s development is rooted in Germany, where the globally led engineering team created the award-winning Opel Insignia – the 2009 European Car of the Year. The Insignia has garnered more than 31 prestigious awards and is one of the best-selling midsize sedan in Europe. Regal will bring all of Insignia’s award-winning design, technology and European-inspired performance capabilities to the American market.

Regal will initially be offered in premium CXL trim only, with additional trim levels to be offered in the 2012 model year. The well-equipped Regal CXL includes the following as standard or available equipment:

* Standard 2.4L Ecotec direct injected engine rated at an estimated 182 horsepower (136 kW)
* Available 2.0L Ecotec turbocharged and direct injected engine rated at an estimated 220 horsepower (164 kW) – available late-summer 2010
* Both engines have a six-speed automatic transmission standard with driver-shifting control
* Estimated 30 mpg on the highway with the 2.4L and 29 mpg highway with the 2.0L turbo engine
* MacPherson strut front suspension and four-link independent rear suspension
* All-new Interactive Drive Control System (IDCS) available with the 2.0L turbo, offering driver-selectable suspension settings and automatic driver suspension setting adaptability
* Four-wheel disc brakes with four-channel anti-lock braking system, brake assist and electronic parking brake
* Standard StabiliTrak stability control system and full-function traction control
* Standard dual-stage frontal air bags, side-curtain air bags and pedal-release system; rear-seat thorax air bags available
* Available navigation system, Harmon Kardon sound system, internal flash drive (1GB), hard drive with 10GB for music and USB port
* Standard 18-inch wheels (19-inch wheels standard with IDCS)
* Standard 12-way power, leather and heated driver seat; leather and heated passenger front seat; Bluetooth capability; XM Satellite Radio and OnStar.

Under the hood

Unique with its all-four-cylinder powertrain, the Regal relies on the excellent horsepower-per-liter ratio of the Ecotec engine family to deliver smart, on-demand performance that is also very efficient.

Both the standard 2.4L engine and the available 2.0L turbo use direct injection technology to optimize performance, reduce emissions and maximize fuel efficiency. The 2.4L is the same engine offered in the Buick LaCrosse, but in the smaller, lighter Regal, it delivers more agile performance. The 2.0L turbo cements the sport sedan credibility of the Regal, with on-demand power comparable to a V-6, but the inherent efficiency of a four-cylinder. To ensure responsive power across the rpm range, the 2.0L turbo uses a twin-scroll turbocharger that builds power quickly at lower rpm.

Distinct, uniquely calibrated six-speed automatic transmissions are paired with each engine. Both offer driver shift control that enhances the sporty driving feel of the Regal.

Interactive Drive Control System

Regal’s Interactive Drive Control System chassis technology (available on models with the available 2.0L turbo engine) offers enhanced vehicle stability and greater driving safety. It is designed to change the personality of the car based on the personality of the driver. A sophisticated driving mode control module continually monitors driving style utilizing yaw rate, lateral and longitudinal acceleration, steering wheel, throttle and vehicle speed. It defines the dynamic vehicle state, including acceleration, braking and cornering, to optimize chassis reactions. It also executes all of the IDCS driver selections.

All four dampers are electronically controlled and continuously adapt within milliseconds to the prevailing road conditions, vehicle movements and individual driving style. Chassis settings are adjustable by the driver, with Normal, Tour and Sport settings.

IDCS allows the driver to choose between three different operating modes that change the suspension settings, throttle response, shift pattern and steering sensitivity through the variable effort steering system. The three modes deliver three types of experiences:

* Normal – balanced and optimized for all driving situations
* Tour – optimized for comfort and relaxed driving on long journeys
* Sport – optimized for road holding; enthusiast driving .

Selecting “Sport” mode optimizes the car for dynamic driving, tightening the suspension and steering response and speeding up the reaction of the automatic transmission. The “Tour” mode is optimal for long-distance cruising or rough road conditions, providing an increase in comfort. “Normal” or Default Mode is the perfect all-around setting for daily commuting and city traffic. The other major benefit of Interactive Drive Control is that it automatically adapts Regal’s performance settings to individual driving styles. When a driver begins to drive more aggressively it will tighten the suspension and increase steering effort and change to a more aggressive throttle response. When the vehicle senses that the driver is doing relaxed cruising, it adjusts settings for rolling smoothness and comfort.

Apart from a more rewarding driving experience, IDCS also offers safety benefits in emergency situations. For example, if an obstacle must be avoided when the car is in Tour mode, various chassis sensors convey this to the DMC and the dampers are stiffened within milliseconds, delivering greater body control.
