Expected Launch: 27 November 2014
Expected Price: 1 - 1.30 crores
Overview
In 2013,BMW created a bit of history by introducing a new line of vehicles in its range. The performance two-door versions in the 3 Series and 5 Series became the 2 Series and 4 Series while the M3 and M5 are now four door performance cars. The Indian arm of the German automaker has previewed the M4 on its official Facebook page and we expect that it will be launched here within the next few Days.
BMW M4 is based off the 4-series but boasts more underhood might, a thoroughly reworked suspension and racier styling. It also packs a host of new technology features and lightweight materials.
In place of the M3 Coupe's characterful but thirsty 4.0-liter V8 is a downsized 3.0-liter inline-six that relies on twin turbochargers to produce 425 horsepower and 406 lb-ft of torque from just 1,850 rpm all the way to 5,500 rpm. Those figures represent gains of 11 ponies and, more importantly, 111 lb-ft of twist compared to the old eight, with peak torque arriving 2,050 rpm earlier.
Transmission options include a six-speed manual and a seven-speed dual-clutch automatic. The standard-equipment stick shift features a rev-matched downshift function and helps the coupe to accelerate from zero-to-60 mph in a claimed 4.1 seconds, while the seven-speed dual-clutch boasts launch control and a slightly quicker sprint time of 3.9 seconds. Also part of the septa-cog's bag of tricks is a "Stability Clutch Control" function that opens one of the clutches in order to quell understeer.
Fuel economy is rated at 17 mpg in the city and 26 mpg on the highway with the manual, while the dual-clutch is good for 17/24 mpg.
M compound brakes on all four corners and a stiffened, track-tuned suspension keep M4's prodigious power in check. As expected, the M3 Coupe's hydraulic-assist steering gives way to a new, more efficient electric-assist setup with three different effort modes. An optional Adaptive M suspension with electronically-controlled dampers also offers a trio of modes, allowing drivers to prioritize ride comfort or handling agility.
All M4s are equipped with an Active M Differential that keeps tabs on throttle inputs, the rotational speed of the wheels and the car's yaw rates in order to maximize traction.
Thanks in part to the increased use of carbon fiber reinforced plastic and aluminum in the body and suspension, the M4 is an impressive 176 lbs. lighter than the M3 Coupe. Contributing to the weight loss are components like the six-speed manual (-26 lbs.), smaller engine (-22 lbs.) and carbon fiber roof (-11 lbs.).
Changes in the parts , Inside and Outside
In the outside, the M4 wears a heavily-sculpted front bumper, a discreet hood bulge and flared fenders all around. Air curtains mounted in the front apron team up with "Air Breathers" - that's BMW-speak for fender vents - to optimize airflow around the wheel arches and improve aerodynamics. Around back, a diffuser with inset quad tailpipes and a Gurney-style spoiler provide both style and function. Eighteen-inch rims are fitted as standard, while 19-inchers can be specified as an option.
The M4's cabin is closely modeled after the standard 4-Series, which means it includes a quartet of simple, driver-friendly analog gauges and a tablet-style 6.5-inch display screen mounted atop the dashboard that displays stereo and vehicle information. Shell out for the optional navigation system, and the screen is upgraded to a larger 8.8-inch unit.
All secondary systems are controlled through BMW's iDrive infotainment setup, which has evolved over the years from a bewildering complex unit to surprisingly simple and user-friendly system. Redundant controls on the steering wheel and dashboard provide alternate means of accessing the electronics.
The optional navigation system is available with Google point-of-interest search and real time traffic information, and it also features a touchpad mounted on the iDrive knob that lets users write out phone numbers, contact names and navigation destinations - and also zoom in or zoom out the map - with a finger.
Setting the M4 part from the standard 4-Series is an M-specific instrument cluster, a sporty three-spoke multifunction steering wheel, sports seats and carbon fiber trim on the dashboard and on the center console. Naturally, liberal helpings of M badging are also part of the package.
Standard and Optional Specification
The M4 is fitted as standard with leather upholstery, heated and power-adjustable M front sport seats, a navigation system with 20GB of audio storage, rain-sensing windshield wipers, adaptive Xenon headlights, heated and power-adjustable exterior mirrors, a Homelink universal garage door opener, an AM/FM/CD stereo with HD radio, Bluetooth connectivity with audio streaming, AUX and USB ports and 18-inch alloy wheels.
Notable options include a head-up display, a front collision warning system, full LED headlights, and, on the performance end, lightweight and extra fade-resistant carbon ceramic brakes.
Occupant Safety feature
All M4 coupes come standard with dual front, front side, front knee and full-length side curtain airbags, in addition to traction and stability control systems.
Lane departure warning, frontal collision warning and active blind spot detection can be spec'd as part of the Driver Assistance Plus package.
Key Competitors
The alternative competitor of BMW M4 include the Audi RS 5, which packs a 450-horsepower 4.2-liter V8, and the striking, potent Lexus IS F. The Mercedes-Benz C63 AMG Coupe and Cadillac CTS-V are also strong options, although both will be redesigned in the near future (and an ATS-V Coupe is expected to be positioned as Cadillac's M4 fighter
