EV Vs HV

 

 

 

 

 

 

 

 

 

 

 

 

It’s time for the big showdown between the two rivals hoping to knock internal combustion engines off the top spot in the world of automotive power. (cue drumrolls, flashing lights blaring heavy metal music and a hyperventilating commentator).  In the green corner, we have… Electricity!  In the other green corner, we have… Hydrogen!  Which of these two mighty rivals will win the title for best engine type and come out champion and win the Green Energy title?

OK, settle down.  Deep breath and time for me to stop channelling the pro wrestling I watched the other night when I was in need of a good laugh.  Right, that’s better.  Now to continue with a discussion of whether hydrogen-powered vehicles or EVs are the best.

Of course, one has to look at all aspects of motoring to decide what’s best. What’s more, when it comes to individual decisions as to what car you want to buy and drive, your personal priorities will come into play. So, without further ado, let the contest begin…

Environmental impact and emissions: On the road from the end-user perspective, it’s a draw.  Running EVs and hydrogen doesn’t pump out pollution or greenhouse gases.  However, the way that the electricity is generated or the hydrogen gas is produced may have to be taken into account. If the widespread uptake of EVs means that power companies have to fire up otherwise disused old coal- or gas-fired generators, EVs might not be all that green.  If the power comes from hydro, wind or solar, then it’s all good.  Similarly with hydrogen: if the process of getting said hydrogen into a fuel form can be done without chewing through non-renewables or pumping out nasties, then it’s all good – and we’re working on that, as we’ve discussed in an earlier post.

Maintenance: Assuming that you can find a mechanic that can deal with EVs (there are more of these knocking around these days) and/or hydrogen vehicles (we need a nice little abbreviation for these: what about HVs?), this is another draw.  Both types of vehicle have fewer moving parts than what’s needed in an ICE (internal combustion engine) – both involve electric motors that create rotational motion directly rather than relying on a controlled explosion to push a piston that turns into rotational motion.  Fewer moving parts means less friction, which means less wear and tear.  However, to be fair, EVs and HVs haven’t been around quite as long, so we will have to wait a bit and see what happens as they get older.

Accessibility: OK, here EVs win hands down.  Charging points can be found in all sorts of places and every time I go to my favourite holiday spot, I come across a new charger where there wasn’t one before.  You can also get charging points for your home so you can charge an EV overnight.  Although our very own CSIRO are working on ways to make transportation and storage of hydrogen easier, we still don’t have very many hydrogen bowsers out there… or at least not yet.

Cost: At the moment, electricity is cheaper to get than hydrogen fuel, so this is another win for EVs.

Time: As a lot of you have already discovered, it can take quite a while to charge the battery of an EV up to full, kind of like it does with your phone or laptop. Even the very fastest superchargers take half an hour to get a battery to 100%. However, hydrogen pumps as easily as petrol or diesel, and you all know how quick that is, so HVs win here.

Range: Another very clear win for hydrogen. In 2017, the Toyota Mirai clocked up 502 km, while a test version of a Tesla picked up somewhere between 397 and 506 km.  In practice and with everyday people driving, the range of HVs tends to be a lot longer than that of EVs.

Specs:

The Telsa Roadster (due for release in 2020) boasts some specs that make all the other supercars, muscle cars and hypercars look like Granny’s little runabout: 0–62 mph (that’s about the same as 100 km/h)) in 1.9 seconds, a top speed of 250 MILES per hour and a reputed 10,000 Nm of torque according to Elon Musk.  Yes, I’m counting those zeroes as well and wondering if that’s for real.  A nice nerd has explained how this figure might be a wee bit misleading, as Tesla’s talking about wheel torque, not engine torque:

On the HV front, the Pininfarina H2 Speed racing machine claims to do the 0–62 mph sprint in 3.4 seconds and has a top speed of 300 km/h and a maximum power output (from four engines combined) of 480 kW; torque figures are hard to come by.

Actually, I would quite like to see a real head-to-head race between the Pininfarina H2 Speed and the Tesla Roadster, and not just because it would be cool to see the Tesla’s acceleration in action.  One of the things that puts me off traditional motor racing a bit is the engine noise and the smell of the fumes, but when electricity and hydrogen compete, these would be totally gone and that’s the whole point of EVs and HVs.  We can probably say now that the Tesla would win the sprint, but over a longer race, the quicker refuelling time of the H2 Speed might make up for this.

Private Fleet Car Review: 2019 Kia Cerato GT Sedan & Cerato Sport Hatch

This Car Review Is About: The latest offerings from the long running Cerato range, specifically the restyled sedan and hatch bodies, in GT and Sport trim. There is the S, Sport, Sport Plus, and GT. The S and Sport can be optioned with a Safety Pack.Under The Bonnet Is: A choice of a turbocharged 1.6L driving a seven speed dual clutch auto in the GT, against a 2.0L non-turbo and six speed standard auto for the Sport and S. The GT gets the powerhouse 150kW turbo which delivers 265Nm of twist across a flat 1,500rpm to 4,500rpm “torque curve”. The Sport has a very good 2.0L, with 112kW and 192Nm at 4,000rpm. The S is the only version with a manual six speed available.Economy for the pair is tight; the bigger engine is quoted as 7.4L/100km for the combined cycle, with the turbo 1.6L at 6.8L/100km. Our highway drives saw 5.8L/100km for the 1.6L Cerato GT sedan, the Cerato Sport hatch clocked a 6.9L/100km. Overall activity saw 7.4L/100 for the hatch as a final average on its return, with the sedan at 7.1L/100km. That’s running regular unleaded from a 50L tank.

What Do They Cost?: Kia says $32,990 plus on-roads for the GT sedan, $25,790 plus ORC for the Sport hatch, and if you opt for the Sport+, that’s $28,840 plus ORC. There are ten colours available, with the GT getting its own Sunset Orange shade. Paints classified as Metallic or Pearl are a $520 option.On The Outside Is: A choice of a sleek sedan or a sleek hatch. They’re essentially the same until the rear of the rear doors, and the hatch has a manual tail gate, a more pronounced taper to the rear roof line, and BMW-esque LED tail lights. Essentially, as the GT has a full suite of LEDs for both headlights and DRLs, whereas the Cerato Sport Plus has normal headlights and LEDs for the daytime running lights. Both ends, though, have the indicator lamps set below a driver’s line of sight, rather than being up in the head and tail light clusters.

The GT also has specific wheels and tyres. 225/40/18s with Michelin rubber wrap ten dual-spoke design alloys. The Sport has 225/45/17 alloys of a similar yet different design. The spare is a temporary sized one with a steel rim.Overall dimensions show just how big a modern small/medium sedan is. At 4,640mm in length, they’re bigger than the legendary EH Holden, which was 4,511mm. The Cerato’s height is 1,440mm except for the GT which is 5mm lower. The blocky EH stood 1,478mm. Where the classic Holden won was on weight. At 1,118kg it’s 200kg to 250kg lighter than the Ceratos.

There’s a couple of other minor differences too; the Sport Plus gets body coloured wing mirror covers, whilst the GT has high gloss black covers. Both have heating for the mirrors. The GT has twin chrome tipped exhausts, and the Sport Plus a single well pipe. There’s also a slight difference between the sedan and the hatch when it comes to opening the boot lid. There is a release button on the key fob, and a lever inside. But there is not a tab on the bootlid to open the boot. Once open there’s another design hiccup. The rear seats don’t have a shoulder mounted seat release mechanism. To flip the seats in the sedan the boot must be opened, a boot mounted lever puller for either the left or right hand seat, then it’s back to the rear seats to actually fold them down. The hatch does away with this ridiculous idea by having a boot-lid mounted tab. On the Inside Is: A surprisingly low toned interior. The GT is black upon black, having only subtle red piping on the seats and alloy look plastics around the gear selector, air vents and dash strip, central steering wheel spoke, and door handles, to break up the black. Under the driver’s foot is alloy pedals in the GT. The Sport Plus as tested had a similar look to the dash but had a lighter shade of material from the doors upwards and a charcoal/grey cloth trim to the seats. The GT’s driver holds a flat bottomed steering wheel.

Actual plastics look and feel is cheapish. There’s little, if anything, to differentiate the upper echelon cars from the base model S in this respect, plus there’s a distractingly high level of upper dash reflectivity into the windscreen. The driver’s binnacle display is fully analogue and has a monochrome display screen, not colour. Sound comes from a six speaker system in the Sport Plus, an eight speaker setup in the GT, with DAB tuners across the range plus the now almost seemingly mandatory Android Auto and Apple CarPlay plus Bluetooth.There are four cup, and four bottle, holders in the cabin. Just the driver gets a one touch up/down window switch. The GT gets a wireless smartphone charging pad and it’s a slightly tricky design. A small bump in the plastic on the left hand side will stop a phone from being charged properly if it’s not placed in the holder correctly. There’s a pair of USB ports and a single 12V socket up front as well.

As is the norm now, a touchscreen of 8.0 inches in measurement, and a simple one to use at that, is mounted up high on the dash. Default look is map and audio side by side. As is Kia’s wont, the interface is intuitive and makes using the various functions, and changing settings, fuss free.

On The Road It’s: Not quite chalk and cheese. The turbo in the GT is a firecracker, with verve, fizz, fire and brimstone, belying the 265Nm, as it feels as if there are more. The dual clutch transmission is beautifully matched and the performance potential is huge. Surprisingly, the 2.0L seemed not far off the pace in regards to response and driveability. The smaller engine is a free spirited and easily spun unit however the 2.0L in the Sport was nearly as easy going in how it moved the analogue needle around the dial. The more traditionally oriented six speed auto was nearly as slick and smooth, but simply couldn’t match the bang-bang nature of the dual-clutch in cog swapping.Get and go in both is very good, with the torque spread of the GT’s engine making for a harder run from a standing start. There’s real excitement from the driveline as a straight line run sees the freeway limit reached in what feels like just a breath. The Sport’s 2.0L pulled hard too but in a side by side comparison would be noticeably behind. The dual-clutch also exhibited a trait peculiar to this kind of transmission. Anything from a mild press of the go pedal upwards has the brains of the ‘box working fine, go a little softer, or change from Reverse to Drive, and there’s that customary pause as the brains figure out exactly what the transmission is supposed to do before actually doing so.Handling on both was neutral; the weight of the steering in both was excellent and allowed for a clean judgement of how much input was required to have the nose go where it was desired. On one particular corner the front end would run wide but only at a certain speed and was easily brought back to a controllable level with a back-off and a brush of the brakes. Highway driving has the pair change directions nimbly and the steering & engine choices, left in the default Eco mode, was never needed to be in anything other than that. The GT has a Smart mode which runs between Sport/Eco/Comfort, and effectively learns on the fly as well, helping the on board computers to adapt to an individual driving style.

Ride quality definitely tends towards the harder style yet the GT’s 18 inch rubber doesn’t crash through to the cabin at all. The Australian fettled suspension is well sorted, with work performed on the sophisticated multi-link independent system going to a specific sports tune all-round Braking is superb with the front brake discs growing in size from 280mm to 305mm, making braking a sensory experience and providing millimetre perfect judgement. The Sport lacked little here too, with its braking setup virtually on par. The Sport also has a softer ride setup, and perhaps one that more buyers would choose over the tauter GT for around-town driving.

GT stands for Grand Tourer and so it is with the sedan really showing its mettle on longer runs. The very nature of the torque deliver and the responsiveness of the seven speed DCT suits a good punt and taken westwards along the Great Western Highway, and eastwards on the freeways towards Sydney show what a beautifully setup long distance driver it is. In seventh geqar and barely off idle in cruise mode, the GT is a delight. The Sport’s sixth gear takes the rev point higher and it’s here that the slight coarseness of the 2.0L becomes apparent. It’s not harsh, just noticeable that it’s not quite as turbine smooth or quiet.Of a final note is the aural extension of the engine note into the cabin for the GT. It’s a throaty and rorty sound, not unlike a worked over flat four. But it’s a generated sound, and played via the sound system. It’s a matter of personal taste and unfortunately not one that can be deactivated.

Safety Features Are: strong, naturally. AEB or Autonomous Emergency Braking, with Pedestrian and Cyclist detection, Forward Collision Warning, and Lane Keep Assist are standard. Rear View Camera with dynamic guidelines, Driver Attention Alert Warning, front and rear parking sensors, are also standard.

What About Warranty and Service?: Standard seven years, unlimited kilometres, and capped priced servicing, as per the information here.

At The End of the Drive. Kia has come a HELLUVA long way in the twelve years since AWT was selling cars alongside the brand’s then new cars. The level of technology, safety, the designs, and the change from a non-turbo range to the inclusion of a genuine sports oriented range, such as the Cerato GT, put Kia into a stronger position in the marketplace than it was a decade ago. In an increasingly competitive sales area, the Cerato GT stands out as one to choose from a drivers’ perspective. The Sport is the one for an around town lifestyle. The sedan and hatch have further information available.

Tesla Model 3 Pricing Confirmed For Australia.

Tesla Australia has confirmed the range and pricing structure for the forthcoming Model 3.Built upon a two model range to start, the Standard Plus and Performance, the new entry level range for the electric car makers starts at $66,000 plus on-road costs and government charges. Expected 0-100 time is 5.6 seconds, and expected range from the supercharger capable Model 3 Standard Plus is 460 km. The Performance is listed as $85,000 plus charges. 0 100 is 3.4 seconds and a range of 560km. 20 inch wheels roll around red alloy calipers, with a subtle carbon fibre spoiler providing extra stability when driving in Track Mode.Five colours will be made available for the expected August launch timeframe; Solid Black, Midnight Silver Metallic, Deep Blue Metallic, Pearl White and Metallic Red multicoats. The metallics are $1,400 and the multicoats $2,100 and $2,800 respectively.

The Model 3 will also receive the over-the-air software updates. A major update is the Autopilot facility, which enables the Model 3 to effectively drive itself albeit still under active human supervision. It enables the Model 3 to to steer, accelerate and brake for other vehicles and pedestrians within its lane. The Standard Plus also gets a 12-way 12-way power adjustable, heated, front pair of seats, with premium seat material and trim, an upgraded audio system, plus standard maps & navigation. There is also centre console with storage, 4 USB ports, and docking for 2 smartphones. Entry is via the Tesla keyfob or a new smartcard system.LED fog lamps, Automatic Emergency Braking, Automatic Emergency Braking, Forward Collision Warning and Side Collision Warning will be standard. Buyers of the Model 3 Performance will receive what Tesla denote as the Premium Interior Package. Live traffic notifications with satnav maps, a 14 speaker audio system with music streaming, heated rear seats complement the standard equipment in the Standard Plus. Both cars will allow for customisable driver profiles, and everything is set up from a spare looking dashboard, dominated by a solitary touchscreen in landscape orientation.An extra feature to be released later in the year is traffic light and stop sign recognition. This will enable the Model 3 to further enhance its autonomous driving ability, and it’s forecast that the Model 3 will be able to do so in a full city environment. The Autopilot feature is also intended to allow autonomous driving in situations such as vehicle overtaking and on/off-ramp driving.

The exterior design is one familiar to anyone with a Model S. The headlights are subtly redesigned for a more wrap-around look, the roof is a solidly tinted glass item, and the rear is a more traditional boot, rather than liftback, styling.Orders for the Tesla Model 3 are now open and available via the Tesla Australia website.
