Audi RS3
|
|
Since its birth a decade ago, Audi RS3 has been using the firm's unique
5-cylinder engine with 2.5 liters displacement. It produced 340hp in
the beginning, then rose to 367hp and 400hp. The latest RS3 is no
exception. While the familiar 5-cylinder still produces 400hp, the
latter is available earlier than before, from 5600-7000 rpm. Maximum
torque is lifted from by 15 lbft to 369 lbft, available across a wider
band (2250-5600 rpm). Although it makes less power and no more torque
than arch-rival Mercedes-AMG A45 or CLA45 S, the RS3's torque delivery
is far broader. Perhaps this is why Audi claims it takes just 3.7
seconds to sprint from 0-60 mph, a tenth quicker than the AMG. It has
an advantage in top speed as well, because you have the choice to lift
its speed limit from 155 mph to 174 mph or even 180 mph, if you opt for
the RS Dynamic pack and ceramic brakes. The AMG? No more than 168 mph.
In the chassis side, there are upgrades to suspension (lower, stiffer,
stronger, more negative camber etc.), bigger brakes and electronic
control systems. However, the biggest news is abandoning the
long-serving Haldex-clutch-based Quattro system for a new RS Torque
Splitter supplied by Magna. In fact, the same hardware was first used
in the VW Golf R, and a similar one used even earlier on its AMG
arch-rivals. Its design is pretty simple: the prop-shaft drives the
rear axle through a bezel gear. There are 2 multi-plate clutches
attached the ends of the rear axle, each couples to a rear wheel. When
both clutches open, the RS3 runs in FWD mode to save fuel. When both
fully engage, 50 percent torque goes to the rear axle. In corner where
you need to tame understeer or even introduce some oversteer, the
inside clutch opens and the outside clutch engages, so more torque goes
to the outside rear wheel. Therefore, by altering the degree of clutch
engagement, you can control the balance of the car.
Thanks to the new torque splitting device, the new RS3 can introduce
Drift mode to thrill its driver on track. However, unlike the last Ford
Focus RS, the Magna device can never deliver more than 50 percent
torque to the rear axle (unless the front wheels are running on
slippery surfaces while the rears are not). That said, as proved by AMG
and Golf R, the ability of directing all of that 50 percent torque to
the outside rear wheel is already very useful and fun enough.

Aston
Martin Valhalla challenges SF90
|
|
2 years ago, Aston Martin unveiled a supercar codenamed AM-RB 003 in
Geneva motor show. The car was developed together with Redbull Racing
under the leadership of star F1 designer Adrian Neway. It was set to
sit under the range-topping Valkerie,
but still cost a hardly affordable £1 million, with 500 cars
slated to production. An inhouse-developed, hybridized 3-liter
twin-turbo V6 would give the car around 1000 horsepower to spend. Later
on, the car was given a name: Valhalla.
However, when ex-AMG boss Tobias Moers was appointed as the new CEO of
Aston Martin in August last year, he reviewed the product plan and
decided to change the Valhalla. The inhouse V6 was abandoned in the
view of high development costs as well as development prospect (who
would invest a great deal of money into a bespoke new engine these
days?). Instead, he utilizes his relationship with Daimler to secure
the supply of AMG's V8. Here, we are not talking about the detuned
version of AMG 4.0-liter V8 being used by other Aston Martins, but the
most advanced, flat-plane crank version that is until now reserved for
AMG GT Black series. Not just that, it is tuned even higher, thanks in
part to a bespoke roof-mounted airbox and top-exit exhaust, producing
750 horsepower, 20 more than the AMG Black. It revs to 7200 rpm like
the Black.
The V8 is supplemented with 2 electric motors, one incorporated into
the new Granziano 8-speed DCT together with electronic differential,
another drives the front axle. They provide an additional 204
horsepower, making up a total of 950 hp. Performance is at least as
good as Ferrari SF90 Stradale, with 217 mph top speed (against
Ferrari's 211 mph), and 0-62 mph sprint done in an identical 2.5
seconds.
It does have an EV mode, where only the front axle is driving. However,
such mode is good for speeds up to only 80 mph and a dismal 15km (less
than 10 miles) range due to the small battery - believed to be the
6.1kWh unit of the upcoming Mercedes-AMG C63 (yes, the four-cylinder
one). Apart from aiding acceleration, the rear motor doubles as the
power source for reverse, so that the Graziano gearbox can skip a
reverse gear to save weight.
The Valhalla's shape has evolved as well, looking slimmer and richer in
details. In particular, it finally gets a face - the traditional
horizontal grille of Aston Martin, but it still looks like a Le Mans
race car on the road, thanks to a very low stance, a roof snorkel and
fenders that look more like aero foils than part of a solid body. The
car keeps using huge ground effect tunnels, so it can generate 600kg of
down force at 150 mph without resorting to high-mounted spoilers. Now
wonder Aston says it targets at a new Nurburging lap record of 6:30.
The current production car record is held by AMG GT Black at 6:43.6 (a
Porsche 991.2 GT2 is even quicker at 6:38.8, but modified with Manthey
Performance Kit).
Compared with AM-RBV 003, the chassis doesn't change much. It is still
built around a carbon-fiber tub, on which the seats are directly
moulded for an ultra-low driving position (adjustable steering wheel
and pedals adapt to different sizes). Suspensions are double-wishbones
up front, with push-rod operated inboard dampers and springs, and a
multi-link setup at the back. Canadian supplier Multimatic contributes
its Adaptive Spool Valves (ASV) dampers and 2-stage adjustable ride
height and spring rate, both were first used on the current Ford GT.
The wheels are 20-inch up front and 21-inch at the back, shod with
Michelin Cup tires with bespoke compounds. Brakes are Brembo CCM, of
course.
Using a full carbon-fiber structure means the Valhalla can be lighter
than Ferrari SF90, which still employs an aluminum spaceframe structure
like other mainstream Ferraris. Aston targets at a dry weight of
1550kg, 20kg less than the Ferrari. Add around 100kg of water and oil,
the Aston could tip the DIN scale at 1650kg, not what you would expect
for a million-dollar supercar. To make you feel better, Moers has
adjusted its market position slightly, lowering its price tag to
somewhere around £600,000 to £700,000. He said that is a
sweetspot in the market place, more than production supercars like
Lamborghini V12 but not as high as Bugatti / Koenigsegg / Pagani /
LaFerrari / McLaren Ultimate series etc., although you can buy almost 2
SF90s with that money. He plans to build 1000 cars over a period of 2
years, with customer delivery slated to start at Q4 2023, 2 years later
than originally planned.

Hyundai
Elantra N
|
|
Hyundai's N performance brand has built a good reputation with cars
like i30N, Veloster N and i20N. The 4th member of the line is Elantra
N, whose target audiences are American motorists. While I don't think
it could rock the domination of Honda Civic Type R, it offers similar
performance with less money.
The Elantra N employs the same 2.0-liter turbocharged engine as the
i30N, rated at 280hp and 289 lbft of torque, but it can be overboosted
to 290hp for a maximum 20 seconds. Unlike the European i30N, the
America-oriented sports sedan offers only an 8-speed DCT, good for 0-60
mph in
5 seconds flat. An active differential helps it to put down the power
effectively through the front wheels. Oversized 245/35ZR19 Michelin
Pilot Sport 4S rubbers, 360mm front brake discs, front and rear chassis
reinforcing brackings and a rear spoiler complete the performance
upgrade. Still, the ungainly shape of the Elantra base car might let
you down.

Opel Astra
|
|
The new generation Opel/Vauxhall Astra is not only built on PSA's EMP2
platform, but it shares the same size and proportion with the new
Peugeot
308, so only the exterior styling and interior packaging differ them.
At 4374mm long, 1860mm wide and 1470mm tall, it is 4mm longer, 11mm
narrower and 15mm lower than the last Astra. Its 2675mm wheelbase is
identical to that of its Peugeot sister but 13mm longer than its
predecessor. Boot space is quite generous at 422 liters.
Inside, it is very different from the 308, thanks to putting two
10-inch screens inline horizontally, and the instrument is seen through
the steering wheel in conventional way. However, as in the Peugeot but
unlike Volkswagen, some physical switches are retained for easier
control, say, the air-con. Moreover, Opel stresses that the user
interface of the touchscreen is very intuitive, without needing to
access sub-menus. It seems to put salts on Volkswagen's wounds.
As the car is derived from EMP2, there is no surprise in the mechanical
aspects. It rides on struts and torsion-beam suspension, although its
ride and handling tuning biases towards high-speed stability as
demanded by German motorists. Torsional
rigidity of the monocoque is 14 percent higher than the last one.
Powertrain includes 1.2 Puretech 3-cylinder turbo with 110hp or 130hp,
1.6HDi turbo diesel with 130hp or, in the case of plug-in hybrid, a
combination of 1.6 turbo four, a front-mounted electric motor and a
12.4kWh battery for a combined output of either 180 or 225hp.

Lamborghini
Aventador LP780-4 Ultimae
|
|
As indicated by its name, this is the final (production) version of the
Aventador. Its power has risen to 780hp, 10hp more than even the SVJ.
Meanwhile, it cuts 25kg from the outgoing Aventador S, so it boosts the
same power to weight ratio as the SVJ, explaining why it could attain
0-60 in the same 2.7 seconds. The car shares its front end with the
production S, but the tail is taken from the SVJ, which has the exhaust
moved up to make space for a larger diffuser. However, as it lacks the
SVJ's fixed rear wing, it can reach 221 mph, a new height for any
Aventadors or Lamborghini.
Lambo is going to build 600 units of Ulitmae, 350 coupes and 250
roadsters. After that, it will introduce the next generation V12 model,
which will be assisted with plug-in hybrid. Therefore, the Ultimae is
really the ultimate chance to enjoy a pure combustion V12 Lamborghini.

Lotus Emira
|
|
12 years have gone since Lotus introduced its last new car, Evora.
During the tenure of Jean-Marc Gales (2014-2018), Lotus was starved of
investment, so it could only keep squeezing the resitdual values of its
existing cars. Now with Geely's fresh funds and concrete planning, a
new boss named Matt Windles (ex-Lotus and Tesla engineer) and a new
production facility at Hethel that turns to semi-automated assembly
line, a new generation Lotus called Emira is finally born.
Mind you, the Emira is not the exactly the future of Lotus. In fact, it
is a stop-gap car and a bridge from the old Lotus formula to the green,
all-electric and user-friendly next generation Lotus to come in a few
years' time. Lotus makes no secret that it will be the brand's last
model powered by pure combustion engines. If you love the lightweight
formula of Collin Chapman, this might be the last chance to buy a
proper Lotus.
While its appearance bears more to the Eviji electric hypercar, the
Emira is actually derived from the Evora platform. It keeps using the
latter's bonded aluminum extrusion chassis, although Lotus said many
chassis members and dimensions have been altered. Like the Evora, its
engine is mounted transversely behind the cockpit and drive the rear
wheels. Its suspensions are double-wishbones at all corners, without
any kind of adaptive or active functions. Its hydraulic steering, a
dinosaur feature nowadays, is carried over. Likewise, its bodywork is
still made of composites. It produces front and rear matching downforce
without using active aerodynamics. Even the car's dimensions are very
close to the Evora's. At 4412mm long, 1895mm wide and 1225mm tall, its
only noticeable difference is the 55mm gain of width. The 2575mm
wheelbase remains unchanged.
There will be 2 engines on offer, one of them is carried over from the
Evora, too. The supercharged 3.5-liter Toyota V6 produces 400hp and 317
lbft of torque here, curiously less than the last Evora. It comes
together with 6-speed manual or 6-speed automatic. As you can see,
Geely-Lotus is reluctant to investment into combustion technology
anymore.
Another engine will be AMG's 2.0-liter turbo four, comes together with
its 8-speed DCT. This supply contract is made possible through the
relationship of Geely, which has stakes and a board seat in Daimler.
The AMG engine is good for 421hp in A45 S, but Lotus claims only 360hp
on the Emira, not sure if AMG deliberately reserves the best for itself
or if the bespoke intake and exhaust Lotus applied to its mid-mounted
engine compromise its breathing. However, final figures are yet to be
released, as the development of this engine is not finished yet. Lotus
will deliver the Emira from next spring with the V6, and the AMG four
will join a quarter later.
Read through the specifications, I have to admit a little
disappointing. Weight is claimed at minimum 1405kg, which is 106kg more
than an Evora GT430. 0-60 mph is claimed to be less than 4.3 seconds,
while top speed is up to 180mph, both are pretty slow by nowadays'
standard. A Porsche 718 Cayman 4.0 GTS will do 0-60 in 3.9 seconds, and
it is likely to undercut the Lotus as well. The Emira will start at
just under £60,000 for the 4-cylinder model, so the V6 may rise
to at least £75,000, or £10K more than the Porsche. Without
offering more performance for the buck, how can Lotus beat Porsche?
Admittedly, the Emira is a very different kind of Lotus. Have you ever
imagine a Lotus to offer these features? An easy-entry cabin,
sufficient luggage space (151 liters of boot plus a 208-liter cargo
space behind the seats, as it gets rid of the Evora's +2 seats), door
pockets large enough to hold 500ml bottles, cup holders (and 2 of
them), storage cubbies for phones and sunglass etc., a largely
soft-trimmed cabin, a 10.25-inch touchscreen and 12.3-inch TFT
instrument, Android Auto and Apple CarPlay compatibility, USB charging
port, a multi-function steering wheel, 12-way adjustable electric
seats, 10-channel KEF sound system, curtain airbags, keyless go,
adaptive cruise control, anti-collision system, fatigue alert, road
sign information, lane departure warning, lane change assist, parking
sensors, rain-sensing wipers... if Lotus can do the quality right, it
is going to enter the territory of Porsche.
I think it can still keep the brand's traditional great handling. With
Evora's chassis basis underneath, there is no reason to doubt,
especially when the car gets wider tracks.
As for styling, I think Lotus design chief Russell Carr has done enough
to bring the Lotus design forward. It is more streamline than the old
Lotuses, yet more dramatic in the curvy fenders and more refined at the
tail design. If these pictures are accurate, its perceived quality is
lifted.
Lotus wants to build 4800 Emiras a year from the new production line.
While it is still not a rolling line, it employs automated guided
vehicles to move car bodies around the site. The paint shop is now
fully automated, and rebotics are used to apply adhesives evenly to
aluminum bondings. It is strange to say the Chinese teaches British to
improve quality, but in this case, Geely is doing so to Lotus. Let's
see if all these changes can turn the fate of Lotus.

BMW
2-Series Coupe
|
|
When BMW turned its 1-Series hatchback and 2-Series Gran Coupe into
front-wheel drive, we expected the 2-Series Coupe would follow suit.
Fortunately, Munich resists the attempt to cost reduction and keeps its
smallest, most affordable coupe in rear-wheel drive format. To that
end, the second generation 2-Series Coupe is built on the CLAR platform
of 3/4-Series and Z4 rather than the UKL2 architecture of front-wheel
drive BMWs and Minis. This means, the new 2-Series Coupe inevitably
grows larger and, in M240i form, has to be bundled with xDrive and
therefore getting more expensive.
These pictures proves the new baby BMW coupe gets significantly longer,
especially the engine bay, resulting in a cab-rearward proportion not
unlike an Z4. It measures 4537mm in length and 1838mm in width and
2741mm in wheelbase, exceeding its predecessor by 105, 64 and 51mm,
respectively, although the overall height is lowered by 28mm to 1390mm.
Although engine side members, spring struts, bonnet and front fenders
are now made of aluminum, these measures save only 10kg, so the new car
should still gain quite a lot of weight. However, by lowering Cd from
0.28 to 0.26, fuel economy is partly compensated.
The model range starts from 220i, whose 2-liter turbo engine is good
for 184hp and 0-60 in 7.1 seconds. Next is 220d turbo diesel, with
190hp and 0-60 taking 6.6 seconds. 230i employs a 245hp version of the
turbo four, while the range-topping (before M2) M240i xDrive employs
the same 374hp 3-liter straight-six turbo from the M340i and M440i. The
latter goes from 0-60 in 4.1 seconds, 3/10ths faster than the old,
340hp and rear-drive M240i. All engines mate with 8-speed ZF automatic,
so drivers preferring stick shift will be disappointed.
The M240i xDrive employs a rear-biased 4WD system which disengages the
front axle in normal driving. M sport active differential is standard,
while adaptive dampers and variable ratio steering are optional.
Performance aside, the biggest improvement of the new 2-Series Coupe is
the interior, which mirrors those of its latest siblings.

Bugatti
merged into Rimac
|
|
The deal has been circulating for some time, and now it is official.
Bugatti will merge into Rimac. Currently, Bugatti is wholly owned by
Volkswagen group via Porsche. Its future has been in doubt for some
time because the group seems reluctant to invest a great deal of money
into the next generation Bugatti, presumably an electric hypercar.
Meanwhile, Porsche also owns 24 percent stakes in Croatian supercar
maker and EV technology leader Rimac. Merging the two could benefit
both, while retaining the interest of Volkswagen group.
Rather than selling Bugatti to straight to Rimac, the deal will be
carried out in the form of merger. A new company, Bugatti Rimac LLC,
will be formed, which will be 45 percent owned by Porsche and 55
percent by Rimac group. As a result, Rimac boss and founder Mate Rimac
will be its CEO. This means Bugatti will be effectively absorbed by
Rimac, although Porsche will directly and indirectly control 58.2
percent of its interest. Meanwhile, the existing consultancy services
of Rimac provided to other car makers will be separated into a
technology division, so to assure confidentiality.
What will this mean to the future of Bugatti? While both the German and
Croatian sides provide no details, we can safely assume that the next
generation Bugatti will be developed by the Croatian, which is
expanding rapidly and will open a 2500-strong Rimac Campus by 2023. The
current Rimac Nevera (production version of C_Two prototype) is already
good at 1900 horsepower, 300 more than the most powerful Bugatti.
Expect the next Bugatti will be developed from that basis.
To Rimac, the addition of Bugatti will sort out its long-term
weaknesses: lack of a prestigious brand, customer basis, design and
craftsmanship. IMO, Bugatti could be the main brand Rimac use to sell
hypercars in the future.
The Bugatti HQ and factory in Molsheim, France, will be kept, as are
its 130 employees. However, it is not sure where the next Bugatti will
be built once the new Rimac Campus is opened.
