Unless you have been living under the rock, you have probably heard of autonomous cars getting into an accident. One accident involving the semi-autonomous Tesla Model S unfortunately led to the fatal death of Joshua Brown, the owner of the ill-fated Model S, when his Model S drove underneath a tractor trailer making a left turn. Apparently, Brown's Model S failed to detect the trailer, as observed by Tesla, "Neither autopilot nor the driver noticed the white side of the tractor-trailer against a brightly lit sky". As a result, the Model S failed to apply the brake and hit the trailer's underside, ripping off the Model S roof, consequently killing Brown.

Another accident involving an autonomous car is a Google car which struck a bus trying to switch lane. As highlighted in an article by ExtremeTech, the vehicle being tested, the 2012 Lexus RX450h, thought the bus would give way. In contrast, the bus driver also thought the Lexus will give way. Result? Neither of them budge and they came into contact, damaging the Lexus front left fender, wheel, and driver side sensor.  

What do the two incidences entailed then? Does this mean the claim autonomous cars are safer than human drivers are dubious? Before we go in with guns blazing thinking cars that drive itself around are 4-wheel deathtrap, we should take a deep breath and look at the bigger picture.

Autonomous cars are still at its infancy. More R&D is still on the card. Meaning, it will take years before the software improves. As a comparison, even automatic transmission technology took several years until it becomes impeccably refine in the present day. What used to be a sluggish and fuel guzzling 'slush box', the technology has improved so much that it is not just more fuel efficient than the manual transmission, but also enhances a car's performance level above what the manual transmission used to offer.

If automatic transmission technology can improve, surely autonomous cars can do the same. With some software tweaks, autonomous cars will be able to do what it fails to do today.

In the present state, there may be some negative perception about the credibility of autonomous cars, but with time, autonomous cars will improve so much that it can recognise wide range of road obstacles at every angle.

BMW F10 5 series bowing out with a bang, with the M5 Competition Edition

Source: www.press.bmwgroup.com

Like everything in life, there is the beginning and the end. The same rule applies to cars. Once it reaches the end of its generation, it ceases existence, and a new generation model takes over its place. In the case of the BMW F10 generation 5 series, its end is drawing to a close, with the next generation G30 and its high-performance F90 M5 alter ego slated to take over. But, it would not be a muted farewell as Munich wants to give a special valediction to the F10 series, in a form of BMW M5 Competition Edition.

What better way to close the F10 chapter, other than giving it an extra boost of power to its wonderful 4.4 litre TwinPower Turbo V8. Thanks to recalibration of boost pressure, 600 hp and 700 Nm overall output is yours to play, up from 560 hp and 680 Nm. Result? 3.9 second 0-100 kph time, a good 0.5 second quicker than the non-Competition Edition M5. Before being consigned to the history book, it is a good idea to leave unforgettable performance figure that makes the car meaningful.

It wouldn't be a perfect send off if you end up in the ditch somewhere. So, BMW outfitted an uprated spring, an electronically controlled damper and a thicker stabilizer bar courtesy of the M Competition Package. Also, carbon ceramic brakes housed within the 20-inch 7 double-spoke alloy wheels ensure the farewell party doesn't end with mangled metal for our F10 friend.

Only 200 units are available. Colour wise, there are 2 available colour schemes: Carbon Black and Mineral White, with 100 units each getting either colour schemes.

With the F10 on its way out, hopefully the upcoming G30 and F90 M5 will be even better.

Fiat 124 Spider, an ND MX 5-bodied Italian sports car

Source: https://en.wikipedia.org/wiki/Fiat_124_Spider_(2016)

Ah, the revival of a classic moniker, that captivates car enthusiasts from 1966-85. The Fiat 124 Sport Spider was a roadster that appealed to the enthusiasts looking for a basic top-down sports car during that juncture. Fast forward to 2016, Fiat Chrysler Automobile (FCA) has brought back the 124 nameplate, christened as the 124 Spider. 

Unlike the Pininfarina-designed 124 Sport Spider, the modern 124 Spider is not a result of Fiat and Pininfarina's collaboration, but rather a joint venture with a Hiroshima-based manufacturer who subscribes to the Jinba Ittai philosophy in sports car design. If you can guess what I am alluding to, kudos to you. But in case if you don't, the manufacturer in reference is Mazda. 

The 124 Spider is underpinned by the fourth generation ND Mazda MX-5 (MX-5 Miata in the US). Thanks to findings by Top Gear, the chassis is built in Mazda's Hiroshima factory. The engine, however, is not built by Mazda, but by Fiat instead. In a nutshell, lurking under the 124's bonnet is Fiat's proprietary 1.4 liter turbocharged MultiAir four banger rather than Mazda's 2.0 litre Skyactiv-G naturally aspirated four banger. Result? The 124 Spider makes more power than the MX-5, 160 for the 124 Spider vs 155 for the MX-5. Does not sound much, but every ponies count. Upon completion, the engine is then shipped to Hiroshima where Mazda's engineers marry the engine to the chassis. 

Fiat engineers then applied their own Jinba Ittai to the suspension tuning, with retuned dampers, stiffer springs and anti-roll bar to embarrass the donor car in the twisty bit. 

Taking advantage of the extra low-end torque, Fiat lengthen the gear ratio. The extra grunt at low rev is more than enough to compensate for the longer gearing. 

All these retuning sounds like a recipe for a more unadulterated driving experience. With more power and an uprated suspension, this little pocket rocket may have what it takes to make MX-5 owners clamouring for the 124 Spider.

Brake Override System

Source: http://www.nissanusa.com/blog/brake-override-system

You have just bought yourself a brand spanking new car. You flip through its specification and inevitably come across the term Brake Override System. Wondering what it means? Wonder no more.

Brake Override System is a safety feature that allows the ability to stop a car even with the accelerator pedal depressed at the same time with the brake application.

Why such feature is introduced on modern cars? One notable example that became fodder to the system's introduction is the fatal crash involving Mark Saylor, a California Highway Patrol officer, and his family, when the accelerator pedal of their Lexus sedan became stuck, leading to a deadly runaway car. Investigators blamed the accident on ill-designed floor mat that obstruct the accelerator's movement, meaning the risk of the accelerator not fully releasing is hazardously high. In light of the accident, National Highway Traffic Safety Administration (NHTSA), an executive branch of the US government under the Department of Transportation, has mandated the system to be implemented by every manufacturers in a bid to protect vehicle occupants in an event of stuck accelerator pedal.

How does it work? When the system detects that both pedals are depressed at the same time, it gives the brake more precedence. In a nutshell,even with the accelerator depressed, the system will make it feel like the accelerator is fully released, enabling your brake to slow the car down effectively. This should in theory prevents you from roaring down the highway with a death note sticking on your forehead.

Should this system be featured on every new cars? Like every safety features, one must know how to use it and remain responsible on the road. It is not a great idea to fall into a false sense of security thinking you can drive around like you are in Too Fast Too Furious movie scene. Nevertheless, any features with life-saving potential make great sense as an extra protection to keep you out from a wreck.    

Peel P50

Manufactured between 1962-1965 by Peel Engineering Company on the Isle of Man, this is arguably the most bizarre microcar in automotive history. The car was declared by the Guinness record as the world's smallest production car.

Peel Engineering Company was a manufacturing company based in Peel village located on the Isle of Man's west coast. The company primarily manufactures fibreglass boats and fairings for motorcycles.

This car can only fit 1 person and 1 shopping bag, 1 headlight, has only 1 door slung out on the left side of the car and most importantly, no reverse gear. You heard that right, NO reverse gear. Peel decided to attach a handle bar right behind the car (as shown in above picture) meaning you have to physically walk behind the car and pull the handle bar to get you out of parking bay for instance. Why Peel decided to omit reverse gear is unfathomable (cost cutting???). Drive is transferred to the single rear wheel by a diminutive 49cc engine. 

If there is one great thing about this car (though not necessarily great to everyone) is this car can be driven literally in a tight confine, like your office for instance. No kidding. This car is so small that it can fit nicely, and drive nicely in your office. Check out the TopGear video below and you will see the point.

Honda NSX

What do you get if you take a Honda with Pininfarina-designed body panel and inject sporty DNA into it's vein to challenge the likes of Ferrari? The answer is the Honda NSX. Though it went into production in 1990, it's development began in 1984.

Tracing it's root back to 1984, Honda approached Pininfarina, an Italian coachbuilder, to commission the HP-X (Honda Pininfarina eXperimental) concept with a 2 litre V6 engine mounted amidship.

During it's development period, the Honda management figured they could create a supercar that rivals the performance of the Ferrari while offering stellar reliability and lower price tag. As a result, the HP-X concept evolved into the NSX (New Sportscar eXperimental). 

Honda set the Ferrari 348 as a benchmark. To fulfill Honda's vision to put the 348 to shame, out goes the 2 litre V6 from the concept and in goes a more powerful mid-mounted transverse 3 litre VTEC DOHC V6 with a variable length intake manifold that churned out 270 bhp to the rear wheels via a 5 speed manual. The use of titanium connecting rod further optimised the output of the 'Ferrari burner'. 

In the chassis department, the Honda engineers received a helping hand from the late triple F1 champion, Ayrton Senna who clinched the 1988, 1990 and 1991 title driving for the McLaren Honda team. Thanks to his input, the NSX chassis gained the much needed rigidity, and much beefier double wishbone suspension all-round, endowing Honda's answer to Ferrari with an impressive cornering speed.

Weight reduction played a crucial role to the NSX's quest to demonstrate its performance credibility. This called for aluminium body panel and aluminium suspension arms. The extensive use of aluminium endowed the NSX with a curb weight of 1370 kg.

Throughout it's production run from 1990-2005, the NSX had gone through several upgrades. Most notably was when the first iteration of the NSX-Type R, or NSX-R, was rolled out the assembly line in 1992 featuring a much larger, more powerful 3.2 litre V6 tuned by Mugen, extensive weight reduction, extra beefy suspension and a more aggressive final drive ratio up to 4.235:1 from the stock 4.06:1 for eyeball-popping acceleration. In 2002, the NSX Type R received a facelift which saw the introduction of carbon fibre to further cut weight and boosting power via engine tweaking. The result is a Nurburgring lap time of 7:56 rivalling the Ferrari F360 Challenge Stradale, set by a former Japanese racing driver and current Best Motoring presenter, Motoharu Kurosawa.

To this writer, the NSX is Honda's stepping stone to challenge the European performance icon. The recently launched second generation NSX with it's new powertrain represents the stride Honda has made to become a major player in the high performance car industry.  

     

Bravo Aston!

Seems like our friend from Gaydon has whipped up something special. Nope, it is not another James Bond special, but it is a rather special offering that will whet the enthusiast's appetite. Meet the new 2017 Aston Martin V12 Vantage S. 

Okay, what is so special about Aston's new V12 Vantage S compared to the previous iteration? Well, it is not really Aston going bonkers with liberating extra juice from the same 6 litre V12 (it still makes the same 563 hp at 6750 rpm and 620 Nm of torque at 5750 rpm). What makes it special is the bit that passes the V12 power to the rear wheels, the transmission.

What is so special about the transmission I heard you ask? Well, the new V12 Vantage S is a departure from the previous model where manual was not even an option (only a 7 speed Sportshift III automated manual was offerred mind you). This time round our Gaydon friend has shoehorned...hold your breath...3 pedals and a human-operated H-gate shifter!

It is not a 6 speed, but it is a 7 speed. It is not just a 7 speed, but it is a 'dogleg' transmission. Dogleg? What is that? It is basically 1st gear sits where 2nd gear should be like on traditional shift pattern, meaning 1st gear on dogleg transmission is to the left of neutral and down. This layout is popular on high performance sports cars and racing cars as 1st gear is seldom used. This allows a faster shift to the gears most often used, such as 2nd and 3rd gear as they are inline with each other requiring just a straightforward shove back and forth.

To top it off, the transmission is equipped with the AMSHIFT, which automatically blips the throttle on downshift to simulate a clean heel toe downshift, made possible by clutch, gear position and propshaft sensor. If you wish to do your own heel toe, the system can be turned off.

The return of manual in the V12 Vantage S after a brief hibernation should be a welcome relief to the enthusiasts camp. The 7 speed Sportshift III automated manual remains an option in the new Vantage S if clutching in and out is not your idea of driving.
