Woodcliff Lake, NJ – May 24, 2012 6:00pm EDT/3:00pm PDT … The newly updated 2013 BMW 7 Series will again set new benchmarks in its class for performance, luxury, efficiency and safety. The updates include significant powertrain upgrades for 740i/Li and 750i/Li models –including BMW’s 8-speed Steptronic automatic transmission, xDrive – BMW’s intelligent all-wheel drive system – now available for the 740Li, as well as a completely new powertrain for the ActiveHybrid 7. The new 7 Series boasts a revised exterior that features new technologies such as available LED headlights. The interior of the new 7 is similarly enhanced with a newly redesigned iDrive system and the availability of an optional Bang & Olufsen High-End Surround Sound system. The new 2013 7 Series arrives in US BMW center showrooms in late summer 2012, expect for the ActiveHybrid 7 which arrives in early fall.
In 2003, from June to December, BMW made 1385 CSL versions of the E46 M3. CSL stands for “Coupe, Sport, Leichtbau”, hinting that BMW had designed a car even faster than the standard E46 M3.
Obviously, it is not easy to improve on an E46 M3, as it already has all the major BMW M features. Therefore, the CSL has small improvements, but lots of them:
1) CSL is lighter
2) CSL has more power
3) CSL has suspension and steering upgrades that improve handling
4) CSL has improved aerodynamics
5) CSL has better grip
All those small improvements together amount to quite a significant performance increase. At the Nürburgring, the E46 M3 has clocked a very impressive lap time of 8:22. The CSL has a time of 7:50. That is a night-and-day difference.
As part of the extensive weight saving program, some equipment was simply left out. There is no navigation, sunroof, fog lights or leather seats. In fact, the car could even be ordered without air-conditioning and a radio, both being quite heavy items to drag around a race-track. And where it really counts, some parts were replaced by much more expensive lightweight items, such as the wheels, front apron, roof, bootlid, rear window and front seats.
To further improve the performance, engine power was increased to 360hp, which is 17hp more than in the standard E46 M3. Suspension, steering and brakes were upgraded. Front splitters and a redesigned bootlid were included to reduce aerodynamic lift. And to perfect the masterpiece, semi-slick Michelin Pilot Sport Cup tires were the choice.
BMW still wanted, however, to maintain the everyday usability of the car, so it continued to have some equipment that many sports cars don’t, such as rear seats (that even fold for extra storage capacity), power windows and mirrors, and reading lights for 4 people!
Why Use Wheel Spacers?
-Appearance. You want to push the wheels out for a better stance and more aggressive look. This is totally subjective to your personal tastes. And we can’t tell you what to like…
-Clearance. Many wheels are not compatible with big brake kits. The spoke of the wheel will scrape the new brake caliper and you need a wheel spacer to push the wheel spoke away from the caliper.
-Correction. You may have bought a set of wheels that don’t have the correct offset for your car. The offset may be too high, resulting in the wheels sitting too far inward. This is both ugly and incorrect as the tire can now rub on the inside wheel well, or on suspension components, etc. A wheel spacer will push the wheel out and ‘correct’ the offset.
-Handling. By spacing the wheels further apart, you can make the car more stable and corner better. You can gain a similar effect as adding a wider wheel without the added weight and expense.
