Audi Q5 Hybrid Fuel Cell technical revealed

0 comments


Audi has brought the experimental Q5 Hybrid Fuel Cell (HFC) to the Michelin Challenge Bibendum, an event showcasing sustainable mobility technologies, which took place at the old Berlin airport (Tempelhof) this past weekend (May 18 to 22).

With the Q5 HFC, Audi is exploring the potential of combining hydrogen fuel cell technology with a hybrid drivetrain for greater range and efficiency over a standard hydrogen-power car (which generates electricity to drive the vehicle).

The Q5 HFC features two high-pressure cylinders where the hydrogen is stored at a pressure rate of 700 bar (10,153 psi). The fuel cell is made of a polymer electrolyte membrane (PEM) and has an output of 98 kW (133 PS / 131 bhp). A 1.3 kWh lithium-ion battery is also able to store energy while two electric motors mounted close to the wheels, with a combined output of 90 kW (122 PS / 121 bhp) and up to 420 Nm (309.78 lb-ft) of torque, drive the Q5.

Audi did not provide further details on range or fuel-economy but the model is still in the very early stages of testing.

All hydrogen-powered cars are zero-emission vehicles, emitting only water, but this Q5 HFC may make the real-world viability of a hydrogen fuel cell car far more of a possibility.

Porsche Panamera Stingray GTR by TOPCAR

0 comments



TopCar has released the first details about their new styling package for the Porsche Panamera.

Dubbed the Stringray GTR, the body kit features new bumpers, widened fenders and modified doors. Additionally, there's a new hood, extended side skirts, an aggressive diffuser and a massive rear wing. The GTR kit was created to satisfy client's requests for more aggressive and "charismatic" styling compared to the original Stingray kit.

Besides the styling enhancements, customers can order a bespoke interior and two performance packages for the Panamera Turbo. The first option enables the twin-turbo 4.8-liter V8 to produce over 600 hp (447 kW / 453 hp) thanks to a new intake manifold, a high-flow air filter and a sports exhaust system. Turning things up a notch, there's also a 700 hp (522 kW / 710 PS) package which has more "sophisticated" modifications.

Regardless of the options, the styling package is priced from €45,000 and production will be limited to 25 units.

VW Golf BlueMotion Review vs Toyota Prius

0 comments



The Volkswagen Golf BlueMotion uses just 3.8 litres of diesel per 100km. That’s less than the Toyota Prius and without all the fancy hybrid

Buying a current-generation hybrid has all of a sudden become an almost pointless exercise. You can now buy a German built Golf that uses less fuel and costs thousands less.

The Volkswagen Golf BlueMotion is the most fuel efficient Golf of all time. Its 1.6-liter, four-cylinder turbo-diesel 77kW engine (250Nm of torque) uses 0.1L/100km less fuel than the all-mighty Prius and it doesn’t even need to carry around batteries and an electric engine.

Volkswagen may be building hybrid and electric vehicles in the near future, but while it perfects that technology the German powerhouse has managed to showcase just how fuel efficient conventional vehicles can be if the right supporting technologies are applied.

Previously the most fuel efficient Golf was the Golf 77TDI, using 4.9L/100km. The BlueMotion essentially makes use of the same underpinnings except it harnesses fuel-saving technologies such as better aerodynamics, start-stop engine system and brake energy recuperation.

As a vehicle, the Golf BlueMotion is just a Golf. It drives like a Golf, it handles like a Golf and is just as practical as one. Volkswagen’s entire marketing campaign for the BlueMotion is based around the tag line “You don’t have to be enviro-mental when you can be enviro-normal”. A clever play on words that is meant to highlight the fact that the Golf BlueMotion is not a car that compromises on features and practicality just to be fuel efficient.

The German company will not be advertising the BlueMotion against the Prius. It believes the BlueMotion can stand on its own feet and prove its credentials without needing to put down the competition directly.

Available as a five-door, five-speed manual only, the Golf BlueMotion is likely to only attract certain buyers. It will no doubt lose sales as a result of not being available as an automatic (DSG) and may also be disadvantaged by lack of multimedia support. Volkswagen says the idea of its BlueMotion cars is to be as fuel efficient as possible and that the 3.8L/100km figure was only achievable with a manual gearbox.

If you’re wondering why it’s not a six-speed manual, it’s due to the more appropriate gear ratios of the five-speed manual. Its fifth gear is so tall that it’s actually more fuel efficient in the BlueMotion application than the standard six-speed generally fitted to the Golf range.



So, what’s so different about the Golf BlueMotion and the Golf 77TDI that it replaces. For a start, it sits 10mm lower on sports suspension, comes with a modified radiator grille, bumpers and side skirt extensions in R-Line styling and rides on 15-inch alloy wheels with low resistance tyres (195/65 – no spare wheel for weight reduction). All of this is done for better aerodynamics. It makes use of start-stop technology, which means the Golf will turn itself off when it’s stopped in traffic. It will only turn the engine off if the BlueMotion is stationary, gear is in neutral and the battery is operating normally.

Start-stop technology has been available in many other vehicles for some time, but for the majority of first-time users it will come as a bit of a shock when their vehicle turns itself off each time it stops. It will take a few hours to get used to, and the most important thing to know is that it will instantly turn back on when you engage the clutch. It does this so quickly that there is no need to wait for the engine to re-engage before driving away. By the time you’ve engaged the clutch and selected first gear the Golf BlueMotion is ready to go. Given how long one can spend in traffic, this system helps save fuel when stationary but can also be switched-off if needed.

When the Golf BlueMotion is decelerating via the brakes, brake energy recuperation technology uses the kinetic energy of the vehicle to charge the battery. By doing this more intensely when the vehicle is decelerating as opposed to at all times, it eases the load of the engine which has to keep the battery charged. It’s unclear just how much fuel each one of these technologies saves individually, but it’s the total as a whole which manages the remarkable 3.8L/100km figure.

The BlueMotion will also suggest perfect gearshift times for maximum fuel efficiency when driving. This goes a long way to helping you get the maximum fuel saving.

Visually the Golf BlueMotion is an attractive vehicle. There are small BlueMotion badges on the grille and tailgate which, from a distance, can make the car appear to be a special-edition sports model. The lower stance and the more aggressive styling (thanks to the bumpers) make the BlueMotion look much sportier than it really is. If the 15-inch wheels didn’t give it away so easily, it could actually look rather mean – for a hybrid-beater. The rear is also home to smoked lights and a roof edge spoiler in GTI design.

Sit inside and you’ll instantly tell this is a Golf. There are no gimmicks that will tell you how many trees you’ve saved or whether a penguin is thanking you from the North Pole. It won’t even draw smiley faces if you drive economically. It’s all just serious business. A typical Golf.

Nonetheless, the no nonsense approach means soft-touch plastics around the dashboard and doors, comfortable seats in a unique BlueMotion cloth trim, a leather steering wheel and low tyre pressure indicator. Like all Golfs, it can comfortably fit four adults for long distance drives and five if necessary. It’s also as safe as they come thanks to all the electronic nanny controls you can think of (ABS, EBD, Brake Assist, EDL, ASR & ESP) plus seven airbags.

The Golf BlueMotion makes use of an RCD310 multimedia system which has no support for Bluetooth phone connectivity or audio streaming. Given that there are no options available for the model, it also misses out on iPhone/iPod/USB support, which is surprising given the ‘no-compromise’ nature of the BlueMotion’s marketing campaign. Not having Bluetooth available even as an option is disappointing. To be fair, it does have an auxiliary jack which allows nearly all music players to be connected the ‘ancient’ way.



All practicality and features aside, the BlueMotion displayed an average fuel economy of just 3.9L/100km. Only 0.1L/100km higher than the official figure. A positively surprising result.

Unlike the Prius which takes someone with a PhD in aerodynamics and engineering to get the official 3.9L/100km figure, the Golf BlueMotion can easily achieve its quoted figure by an average driver.

The BlueMotion sports surprisingly good ride and handling characteristics. It’s comfortable on rough surfaces but its low sports suspension allows for lively cornering and the 250Nm of torque provide adequate pull for out-of-corner acceleration. A lot more fun to drive than any other super fuel efficient car we’ve ever found ourselves in.

If you can look past the manual-only disadvantage and the fact that it lacks Bluetooth phone and audio connectivity or native support for iPod/iPhones, the Volkswagen Golf BlueMotion is not only the most fun you can have in a fuel efficient car, but it’s also practical, cheap, attractive and a lot more engaging than its competition.
