The BMW M4 is a high-performance version of the 4 Series automobile developed by BMW's in-house motorsport division, the BMW M GmbH, the M4 is one of the Fastest M cars ever produced by BMW achieving 0-100km/h (0-62m/h) in just 4 seconds. Part of the renumbering that BMW splits the 3 Series coupe and convertible models to the 4 Series (to further differentiate with the 3 Series sedans), the M4 replaces the M3 Coupe and Convertible models, as well as the Gran Coupe. Upgrades over the standard 4-Series include: a very powerful and responsive, twin turbocharged engine; improved handling, suspension, and braking systems; aerodynamic body enhancements; interior/exterior accents with the tri-colour "M" (Motorsport) badging; the significantly reduced weight compared to the standard 4 series and its predecessor with an all-new stiffer chassis and extensive use of carbon fiber, especially the roof of the car.

                                

It has a bitter rivalry with the bonkers Mercedes C63 AMG and Audi's RS5, not to mention cars like the Maseratti Ghibli, Alfa Romeo Giulia and Lexus RC-F.

BMW officially presented the M4 concept on August 16, 2013. However, the concept car did not reveal any interior or technical details. On September 25 2013, BMW released technical specifications of the M4 which will be powered by M-tuned S55B30 engine, although it is a 3.0 L inline engine BMW says it is completely different to the N55 engine seen in other BMW 35i models, this engine has been built specifically for the New M4/M3, displacing 3.0 L (180 cu in) and redlining at 7,500 rpm. The rev limiter coming in at 7,600rpm. The engine will use two mono-scroll turbochargers with boost peaking at 18.1 PSI. 

                                 

                                 

The power is rated at 425 hp (317 kW; 431 PS) while torque will be 550 N·m (410 lb·ft). The weight of the 6 speed manual M4 will be 3,556 lb (1,613 kg), with the M-DCT some 40kg heavier. Both 6-speed manual and 7-speed M-DCT transmissions will be available. The 7-speed M-DCT transmission will accelerate the car from 0-60 mph (97 km/h) in 3.9 seconds. The 6-speed manual transmission will do 0-60 mph (97 km/h) in 4.1 seconds.

                                

Carbon fiber reinforced plastic will be used extensively throughout the car, including drive shaft, roof, roof bow, trunk, and front strut brace. For the first time in the M vehicle, an electric power steering unit will be used. The steering system will be specifically tuned for the M3 and M4. The 18 inches (460 mm) and 19 inches (480 mm) wheel options will be available with lightweight forged alloys being standard. The M compound brakes will be standard (in blue), while carbon ceramic brakes (in gold) will be available as an option.

                                 

                                 

The M4 will feature Active Sound ,A live amplification of the engine's natural sound will be inducted into the passenger cabin via the speakers, BMW says this technology is been used because of the well insulated cabin to avoid road / wind noise but still provide the driver the sporty sound of the M powered Engine . There will not be any artificial sound or any pre-recorded track. Overall, 70 percent of the components on the M4 will be standalone compared to the F32 4 Series.

Ford Shelby GT350 2016

            (All wallpapers are hd)

                            

Many used to laugh at it. Now they regret laughing. When Ford first showed off its brilliant GT350 for 2016, everyone took notice. When Ford revealed its arsenal of abilities and specs, their eyes widened, and when Ford revealed its price, they simply popped out. Here was a car with flat plane crank V8, lots of power, good handling, and oodles of style and presence, for a lot less than an M4 with considerably less power. On paper atleast, its a winner.

It produces a good round 510 bhp(as much as the twice as expensive Mercedes AMG GT).

                               



Shelby GT350 (2016-)
For 2015, GT350 has been confirmed, featuring a 5.2 L Flat Plane Crank V8 engine with 526 hp (392 kW) and 429 lb·ft (582 N·m) of torque. The GT350 is more track focused than the GT500, and was bench marked against the Camaro Z28, Porsche GT3, and BMW M4. Notable features are track-focused chassis tuning, significant aero-dynamic changes to include lowering the hood around the engine, two piece Brembo brakes, MagneRide damping option, light weight Tremec six speed manual transmission, Recaro seats, and various light weighting efforts. Specifically a carbon fiber reinforced polymer radiator support that directs cooling channels for various components.

Though not direct competitors, any bloke in a DB9, Maseratti Gran Turismo, Corvette or even an Audi R8 should be wary of pulling up against this beast at traffic lights.

Additional options, such as larger alloy wheels, navigation system, rear backup sensors, a rear backup camera, Blind Spot Monitoring, security system, remote vehicle starter system, SHAKER PRO Surround Sound Premium Sound System, premium leather seating surfaces, sunroof and HID front headlamps are available. Interior color schemes, such as Coral Red and Saddle, are available in addition to the standard Black interior color scheme.

                                

Shelby GT350R (2016-)
A further enhanced and even more limited edition of the GT350 with an "R" package (GT350R) was announced by Ford at the 2015 North American International Auto show in Detroit, to be available to customers later in the year with only 37 units being made. The first GT350R with #001 sold for $1 million at Barrett Jackson Auction at Scottsdale, Arizona.



A combination of changes to aerodynamics and suspension tuning to the new Shelby® GT350R Mustang leads to most race-ready road-legal Mustang ever. Significant engineering innovations result in weight savings, aero improvements to benefit on-track performance; Ford is the first major automaker to introduce carbon fiber wheels as standard equipment on Shelby GT350R Mustang. Items removed include air conditioning, the stereo system, rear seats, trunk floorboard and carpet, backup camera and emergency tire sealer and inflator. Exhaust resonators also have been removed for weight savings with the benefit of creating a sharper exhaust tone.

                                   

The Shelby GT350R is more than 130 lbs (59 kg) lighter than the Shelby GT350 Track Pack model, which has proven its durability in multiple 24 hour racetrack tests. The GT350R also comes with carbon fiber rims which contain NASA technology and weigh only 18 lbs (8 kg) each compared to similarly specified aluminum rims which typically weigh 33 lbs (15 kg) each.



Aside from carbon fiber wheels, larger front splitter and rear wing, Shelby GT350R features distinct design details. Exterior touches include red painted brake calipers, red pin striping at the edges of the optional over-the-top racing stripes and Shelby GT350R badging. Inside is high-contrast red stitching, Shelby GT350R badging and the D-shaped steering wheel fitted with a red center mark at the top.



One optional feature for the GT350R is the GT350R Technology Package, which adds the Ford SYNC 3 multimedia infotainment system, seven speakers, a rear backup camera system, SIRIUS-XM Satellite Radio, and air conditioning. The package is ideal for GT350R buyers who plan to use their car for more than track purposes or for show.

McLaren 570S

The McLaren 570S is a sports car designed and manufactured by McLaren Automotive. It was unveiled at the New York International Auto Show in 2015. McLaren predict the model will help triple the company's sales volume by 2020, with UK pricing scheduled at £143,250 GBP, whilst North American pricing is estimated at $180,000 USD.

It goes up against the brutish Mercedes AMG GT, Porsche 911 Turbo S, the Lamborghini Huracan and the new Audi R8.

Design

The car is to be powered by a new iteration of the 3.8 litre twin turbo V8 engine already used in the McLaren 650S and P1, designated M838T E with thirty percent of the parts redesigned. Arranged in the car as a rear-mid engine configuration, it will deliver 562 brake horsepower (419 kW) through a 7 speed dual clutch gearbox. A total weight of 1,313 kilograms (2,895 lb) give the 570S a power to weight ratio of 428 brake horsepower (319 kW) per tonne, deliver fuel economy of 25.5 miles per imperial gallon (11.1 L/100 km; 21.2 mpg_-US) and CO2 emissions of 258g/km.

570S Rear View

McLaren focused on delivering "day-to-day usability and driveability" against the most sporting model options in its range with increased luggage space, greater interior storage and leather upholstery options.

Variants

540C

540C Front View

At the 2015 Shanghai Motor Show the entry level McLaren Sports Series car the McLaren 540C was unveiled with 533 bhp (540PS). This new entry level model focuses on “day-to-day usability and driveability” even more than that of the 570S with improved city driving and improved ride quality. The 540C will be even cheaper than the 570S at only £126,000 and will go on sale shortly after its Shanghai debut. The 540C will not be for sale in the US due to McLaren wanting to focus on the more powerful 570S model for the US market.

Mercedes AMG GT

AMG's follow up album to the mighty SLS, this one's heading straight for the 911 turbo. Driven by 4 litres of twin turbo charged dry sump V8 charisma, that low slung body with a mile long bonnet and a stuby boot, this macho statement on wheels has lots to entice customers. Though marketed as a Grand Tourer, its performance figures are not short of hardcore, what with it sprinting to 60 mph in 3 seconds dead and not giving up untill your on the loonier side of 186 mph. With the bells and whistles GT S costing $130k, it still is a lot less than what the 911 turbo commands. In the market, it competes with the not so august company of the Mclaren Sports Series, the technofest called Audi R8, and ofcourse, the venerable 911. 

History

                                

The interior of the Mercedes-AMG GT was previewed on April 16, 2014. The car made its debut on 9 September 2014. At launch two models are available: the GT, with 350 kW (476 PS; 469 bhp), and the GT S with 375 kW (510 PS; 503 bhp). The GT has 600 N·m (443 lb·ft) of torque, and the GT S has 650 N·m (479 lb·ft) of torque.

                                 

Mercedes-AMG GT S Formula 1 safety car

The Mercedes-AMG GT S is Formula 1's current safety car, having made its debut in that role at the 2015 Australian Grand Prix.

Mercedes-AMG CEO Tobias Moers promised a Black Series variant of the Mercedes-AMG GT, as well as a GT3 racing and street version, to rival the Porsche 911 GT3. Mercedes-Benz has confirmed that the new Mercedes-AMG GT S will cost starting at $129,900.

Specifications

M178 V8 in a GT. The turbochargers are visible in the centre, beneath a metallic heat shield.

The GT uses a front mid-engine, rear-wheel drive layout, with the engine inside the vehicle's wheelbase. The spaceframe chassis and body are made out of aluminium alloys, while the boot lid is steel and the engine bonnet magnesium. The suspensions are double wishbones front and rear, with forged aluminium wishbones and hub carriers.

The car is powered by a front-mid mounted M178 4-litre twin-turbo V8. This new V8 is in "hot inside V" configuration—with exhaust and turbochargers inside the cylinder banks to reduce turbo lag—and uses dry-sump lubrication. Power is sent to the rear wheels through a transaxle 7-speed AMG Speedshift dual-clutch transmission; the GT S model employs an electronically controlled mechanical limited-slip differential. In Car and Driver's road test, the AMG GT S accelerated from 0-60 in 3.0 seconds and ran the quarter mile in 11.2 seconds.
