2010 Venom GT Hennessey Supercar Concept

Hennessey Performance Engineering today announced that it is introducing the company's first concept car - The Venom GT. Penned by British auto designer, Steve Everitt, the Venom GT would incorporate Hennessey's potent Venom 1000 Twin Turbo Viper V10 powerplant into a light weight mid-engine chassis weighing "under 2,700 lbs". Power would be run through a 6-speed transmission or optional sequential gearbox. With a power to weight ratio of just 2.7 lbs per bhp Hennessey estimates that the Venom GT could attain 0 to 100 km/h times in less than 2.5 sec. and a 0-300 km/h time of around 14 seconds.

The Hennessey Venom GT weights less than 2,400 lbs (1,071 Kg) and to stop the Venom GT, Hennessey added Brembo brakes with 6-piston calipers up front and 4-piston calipers in rear clamping down on 15-inch carbon ceramic rotors. Hennessey plans on building 10 units of the Venom GT annually and four have already been sold at around $600,000 a pop. That means there are only six units left from the first allocation.

SEALY, TEXAS & SILVERSTONE, ENGLAND, March 29, 2010 - Hennessey Performance is pleased to introduce the first official images of its Venom GT supercar. Based upon the Lotus Elise, the Venom GT combines a high-tech, lightweight British chassis with a powerful American V8.

“This is not the first time that Britain and America have joined forces to produce a weapon of mass propulsion”, said company founder and president, John Hennessey. “Over fifty years ago the American-built P-51 Mustang fighter aircraft was flown into history powered by a British Rolls-Royce Merlin engine. Today the Hennessey Venom GT promises to set a new standard of power to weight ratio in the rarefied air of today's supercar market.”

In the case of the Venom GT, less weight means more performance. The Venom GT will have a production curb weight of less than 2,400 lbs (1,071 kilos) aided by its lightweight carbon fiber bodywork and carbon fiber wheels. Stopping power is delivered via Brembo brakes with 6-piston calipers up front and 4-piston calipers in rear clamping down on 15-inch carbon ceramic rotors.

The Venom GT’s base power plant is the supercharged 6.2 liter LS9 V8 (the same as in the Corvette ZR1) tweaked by Hennessey to 725 bhp. The company will also be offering 1000 bhp and 1200 bhp twin turbo V8 engine variants. The mid-engine V8 will transmit its power to the rear tires via a Ricardo 6-speed gearbox.

Hennessey plans to manage power output by using a programmable traction control system. CFD (computational fluid dynamic) tested bodywork and down force will also help keep the Venom stable at speed. An active aero system with adjustable rear wing will deploy under varying conditions on both the road and racetrack. An adjustable suspension system will allow ride height adjustments according to speed and driving conditions. Finally, power will be put to the ground via massive Michelin PS2 tires.

Hennessey will be building the power plants at its Texas facility. The engines will then be air freighted to the company's assembly facility near Silverstone, England where the Venom GT is built and tested. Venom GT buyer will be offered a 1-day driver orientation and instruction program by a Hennessey factory test driver, at a track in the UK or USA prior to delivery.

2011 Nex-Gen BMW Sports Sedan 3 Series Coupe And Convertible

A little after a leaked brochure gave us our first taste of the lightly refreshed 2011 3-Series Coupe and Convertible models, BMW rushed out an official release and a whole bunch of pictures. For the 2011 model year, the Bavarian automaker's bread-and-butter coupe and cabriolet models receive some minor cosmetic touches and updated powerplants.

2011 BMW 3-Series Coupe and Convertible

The most notable - that is, if you're a hardcore bimmer fan- changes on the outside concern the widened kidney grille, reshaped LED headlamps, front and rear bumpers with restyled lower fascias, new exterior mirrors and finally, reworked tail light cluster with a new color scheme.

2011 BMW 3-Series Coupe and Convertible

The only change in the cabin concerns the convertible models and the use of sun-reflective technology to mitigate temperatures on leather seating, armrest surfaces, headrests, and gear shifter. BMW says that this new treatment is able to reduce surface temperatures on dark interior colors by up to 20 Celsius degrees (36 Fahrenheit degrees) and by as much as Celsius degrees (27 Fahrenheit degrees)on light-colored upholstery.

2011 BMW 3-Series Coupe and Convertible

The next-generation BMW 3 Series isn't that far off, with the sports sedan expected to debut sometime in 2011 as a 2012 model. Yet the Munich brand isn't sitting on its hands in the meantime – the current 3 Series coupe and convertible are getting a mild refresh and updated powerplants this spring for the 2011 model year. The most immediately noticeable change are headlamp clusters that get a subtle reshaping to go along with a wider grille and reworked lower front fascia. At the rear, the taillamps retain the same shape, but the reflectors are redesigned with some of the light-pipe styling found in other recent Bimmers.

The 3 Series coupe will now be offered with xDrive all-wheel drive, while the 3 Series convertible gets a new solar reflective leather upholstery that BMW claims helps keep seat temperatures down when the lid is open.

The most significant updates come underhood, where the much lauded twin-turbocharged 3.0-liter inline-six is being replaced by a new single turbo version. The revised engine, dubbed N55, has recently been launched in the 740i and the 535i Gran Turismo. The twin scroll turbo has dual exhaust inlets that allow the engineers to better balance the pulses coming in to spin up the turbine faster. This is expected to reduce the turbo lag that some drivers complained about with the outgoing twin turbo setup.

2011 BMW 3-Series Coupe and Convertible

BMW also claims it has reduced cold-start emissions by routing all the exhaust gases through a single, larger catalytic converter that heats up faster. On the intake side, the throttle is eliminated thanks to the addition of BMW's Valvetronic variable valve control system. The N55 also gets direct fuel injection. The end result is the same 300 horsepower and 300 pound-feet of torque as before, but with a fatter torque curve that maintains its peak from 1,200-5,000 rpm.

2011 BMW 3-Series Coupe and Convertible

The new design of the taillights is unique to the 3 Series Coupe and Convertible. The rear light cluster feature two-piece L-shapes and are further accentuated by a new color scheme. With two rows of light tubes that illuminate simultaneously, they create a night design with depth and dimension. Integrated flush into the body of the car, the lights are split into two sections and extend up the trunk lid, blending with the character lines from the side profile. These styling tweaks have resulted in a slightly longer length and larger overhangs (29mm (1.14 inches) at the front, and 3mm (0.12 inches) at the rear)

2011 BMW 3-Series Coupe and Convertible

Though the updated BMW 3 Series Coupe and Convertible will go on sale this Spring, pricing and fuel economy figures haven't been announced as of yet. The former is expected to fall in the range of the current car's pricing, which starts at $37,075 for the 328i Coupe, $42,535 for the 335i Coupe, $45,875 for the 328i Convertible and $52,075 for the 335i Convertible. The latter is expected to be a small improvement in fuel economy for the new single-turbo engine over the current twin-turbo engine's 17 mpg city and 26 mpg highway.

AIR BAG, como funciona

AIR BAG

Em uma colisão frontal, o motorista e os passageiros de um carro são arremessados para a frente e podem se ferir gravemente ao se chocarem com o volante, o painel ou o pára-brisa. Os air bags, ou almofadas infláveis, protegem as pessoas nos casos de acidente: ejetados do volante ou do painel, se enchem de nitrogênio instantaneamente. O sistema de air bag é formado por sensores eletrônicos, um inflator para produzir nitrogênio e a almofada em si. Os sensores são programados para ignorar as colisões a menos de 16 a 22 km/h. Em um choque forte, a almofada se infla por completo em 1/20 de segundo. Para as pessoas poderem sair, a almofada se esvazia assim que absorve o impacto. Os air bags podem salvar vidas, mas apenas em colisões frontais, sem substituir os cintos de segurança e as ombreiras.

Ao receber os sinais do sensor de colisão, um gerador e calor inflama substâncias químicas para produzir o nitrogênio, que infla o air bag.

Completamente cheio, o air bag absorve o impacto inicial do corpo do motorista, quando este é lançado para a frente.

Tendo protegido o corpo do motorista, o air bag se esvazia, suavizando o impacto. Dois orifícios na parte traseira da almofada deixam escapar o gás.
