Lexus IS


Alpina B5

Summary

Lexus IS

No it isn’t an all-new car. It might look like it, but the 2021 Lexus IS is actually a heavy facelift of the existing model, which originally went on sale way back in 2013.

There have been significant changes to the look of the new Lexus IS, including a revised front and rear end, and the company has widened the track and made “substantial chassis changes” to make it handle more adeptly, too. Plus there is a whole raft of newly added safety features and in-car technology, despite the cabin being, largely, a carryover affair.

Suffice to say that the new Lexus IS 2021 model - which the brand describes as having been “reimagined” - carries over a few strengths and weaknesses of its predecessor. But does this Japanese luxury sedan still have enough quality traits to compete with the likes of its main rivals - the Audi A4, BMW 3 Series, Genesis G70 and Mercedes-Benz C-Class?

Let’s find out.

Alpina B5

The BMW Alpina B5 Bi-Turbo is not actually a BMW. Not according to the German Federal Motor Transport Authority, at least.

Nope, the modifications applied by tuning house Alpina to the 5 Series are deemed so significant that if you open the bonnet and look inside the engine bay, you'll see that the BMW VIN has been struck through twice and an Alpina vehicle number stamped underneath it. 

The B5 is not the first model to be recognised in this way, either; the German government has recognised Alpina as a seperate car manufacturer since 1983.

The B5 has other ‘B' siblings, too. There's the B3 S Bi-Turbo, which is based on the BMW 3 Series, the B4 S Bi-Turbo (the BMW 4 Series) and the B7 Bi-Turbo (I don't need to tell you what this is based on, right?) which I've reviewed, too.

So just what has Alpina done to this unsuspecting BMW 5 Series? Is it really worth the extra money? How does the B5 compare to an M5? Could it actually be superior? And did they really take the speed limiter off to let it warp-speed to beyond 300km/h?

Verdict

Lexus IS7.6/10

The new-look Lexus IS takes several steps forward over its predecessor - it’s safer, smarter, sharper to look at and still pretty well priced and equipped.

It is feeling its age inside, and the competition has moved on in terms of engines and EV tech. But even so, if I was buying a 2021 Lexus IS, it would have to be the IS350 F Sport, which is just the most fitting version of this car, though the IS300h Luxury does have plenty to like for the money, too.


Alpina B57.9/10

The Alpina B5 is a special car – more special than most people will ever give you credit for if you own one. Those that do know what an Alpina is will let you know; people will cross dangerously busy streets to talk to you about your car. Insanely fast, almost incomprehensibly comfortable and effortlessly powerful to drive.

Does the Alpina B5 make a BMW even better? Or do you think the M5? Tell us what you think in the comments below.

Design

Lexus IS8/10

You either get the Lexus look or you don’t, and I think this latest version is possibly more agreeable than the IS in years gone by.

That’s partly because the brand has finally done away with the odd spider-eyes twin-section headlights and daytime running lights - now there are more traditional headlight clusters, which look a lot more resolved than before.

The front end still features a bold ‘spindle’ grille, which gets different treatment depending on the grade, and the front, to my eye, looks better than before but still very much stuck in its ways. 

At the side you’ll notice the giveaway windowline hasn’t changed, despite the chrome trim line having broadened as part of this facelift, but you can tell the haunches have muscled up a bit, with the new IS now 30mm wider overall, and the wheel sizes are 18s or 19s, depending on the grade.

The rear accentuates that width, with an L-shaped lighting signature now spanning the entire re-sculpted boot lid, giving the IS a pretty tidy rear end design.

Overall dimensions for the IS are 4710mm long, making it 30mm longer nose to tail (on an unchanged 2800mm wheelbase), while it now spreads across 1840mm (+30mm) and is 1435mm tall (+5mm).

The exterior changes really are impressive - I think it is a more purposeful but also more pleasant looking car now than it ever has been in this current generation. 

The interior? Well, there’s not a whole lot to talk about in terms of design changes, aside from the repositioned and larger media screen - which sits 150mm closer to the driver because it’s now a touchscreen with the latest smartphone mirroring tech. Otherwise it’s a carryover affair, as you can see from the interior pictures.


Alpina B58/10

Interesting is the right word for it, because while it might be questionable that Alpina's changes to the exterior are aesthetic pleasing, they are definitely intriguing to those who aren't familiar with the brand.

First, there are those 20-spoke wheels. Alpinas have worn this style of wheel forever and they've become the most famous outward sign that this is not just another BMW. So don't under any circumstances take them off and replace them with anything else. You'd be run out of town by the Alpina mafia.

Yes, they're more painful to clean than a cheese grater (trust me, I know. And if you look closely at these images you can see the dirty bits I've missed), but if you really don't like them then perhaps it's a sign this car isn't for you.

Then there's the boot-lid spoiler. It's square and 1980s'-looking, it also appears a bit like it's been bought online and installed by a teenager, but again, this is another Alpina tradition and it suits the car's character perfectly.

All right, those pinstripes; they're known as the Deco-Set and are a hat-tip to the Alpina racecars of the 1970s and '80s. Again, don't take these off, your Alpina will drop through the centre of the Earth in value. These are also part-and-parcel of owning one of these cars. I'm not a massive fan of them.

But I'm all about that front spoiler, with the floating Alpina lettering that you can option in silver, high-gloss black or gold.

Inside, there are fewer Alpina additions, but they're nonetheless unmissable. There's the Alpina-badged steering wheel, and a new virtual instrument cluster, embossed headrests and  illuminated door sills.

There's also the little numbered plaque on the centre console which proves its authenticity, ours was number 49. Out of how many? I don't know. But I do know Alpina produces only about 1700 cars globally a year. Rolls Royce does about 4000. So, you can rest assured your B5 is exclusive.

At almost 5m long, 1.9m wide and 1.5m tall, the B5 is a large saloon, but having recently reviewed the Alpina B7 it feels small in comparison. How does it drive? We're getting there.

Practicality

Lexus IS7/10

The interior design of the IS, as mentioned, hasn’t changed dramatically, and it is starting to feel old compared to some of its contemporaries.

It’s still a nice place to be, with comfortable front seats with electric adjustment and heating across all grades, and cooling on many variants, too. 

The new 10.3-inch touchscreen media system is a nice unit, and means you can essentially do away with the silly trackpad system that still resides near the gear selector, so you may still end up bumping it accidentally. And the fact the IS now has Apple CarPlay and Android Auto (though neither are wirelessly connectable) does further its appeal on the multimedia front, as does the standard 10-speaker Pioneer stereo - though the 17-speaker Mark Levinson unit is an absolute blinder!

The centre stack below the media screen retains a CD player, and still has the electromagnetic temperature adjustment sliders as well. That part of the design is dating it just as much as the transmission tunnel console area, which looks a bit out of touch by modern standards, though still incorporates a pair of cup holders and a reasonably large centre console bin with soft armrest padding.

The front doors feature trenches with bottle holders as well, while in the rear doors there is still no drink storage - a carryover annoyance from the pre-facelift model. However, the middle seat in the back doubles as an armrest with pop-out cupholders, and there are rear air vents too.

Speaking of that middle seat, you wouldn’t want to sit in it for long, as it has a raised base and uncomfortable backrest, plus there’s a huge transmission tunnel intrusion eating into leg and foot space.

Outboard passengers also miss out on toe room, which - for my size 12s - is an issue. And it’s hardly the roomiest second row in this class for knee room and headroom, as my 182cm frame was a touch squished behind my own driving position.

Children will be better catered for in the back, and there are two ISOFIX anchorages and three top-tether attachment points for baby seats.

The boot capacity varies on the model you buy. Choose an IS300 or IS350 and you score 480 litres (VDA) of cargo capacity, while the IS300h has a battery pack that robs it of some boot space, with 450L available. 


Alpina B57/10

Practicality is not really a BMW strong point no matter which model you pick. See, BMW mostly makes the car equivalent of uber-stylish and skin-tight active wear which looks good and performs brilliantly, but sometimes you just want pockets and a bit of room for your… um… bits and pieces.

So while there are two cup holders up front and two in the back, the bottle holders in the doors aren't huge, the centre console bin is on the small side, there's a hidy-hole in front of the shifter, the glove box is just a box for little more than gloves and there's no other great cabin storage options.

Legroom in the rear is good but not great, too - I'm 191cm tall and have about 30mm between my knees and the seat back in my driving position. Middle-seat passengers will also have to straddle the drive shaft hump in the floor. Headroom is restricted in the back, too (you could blame the sunroof) with my hair just skimming the headlining (I do have big hair).

Under that power tailgate, the B5's boot capacity is 530 litres which is 15L more than its big sister, the B7. There are two plastic storage areas either side of the luggage space for wet things. While there is one USB outlet in the front there aren't any in the rear.

Price and features

Lexus IS8/10

The updated 2021 Lexus IS range has seen a number of pricing changes, and a reduction of variants, too. There are now five IS models available, down from seven prior to this update as the Sports Luxury model has been axed, and you can only get the IS350 in F Sport trim now. However, the company has expanded its “Enhancement Pack” strategy across the different variants.

Opening the range is the IS300 Luxury, which lists at $61,500 (all prices listed are the MSRP - not including on-road costs, and are correct at time of publishing). It has the exact same equipment as the IS300h Luxury model, which is $64,500, and that ‘h’ stands for hybrid, which will be detailed in the engines section. 

The Luxury trim is equipped with items such LED headlights and daytime running lights, 18-inch alloy wheels, proximity keyless entry with push-button start, a 10.3-inch touchscreen multimedia system with satellite navigation (including live traffic updates) and Apple CarPlay and Android Auto smartphone mirroring tech, plus a 10-speaker sound system, eight-way power-adjustable front seats with heating and memory settings for the driver, and dual-zone climate control. There’s also auto headlights with auto high beam, rain sensing wipers, power steering column adjustment, and adaptive cruise control.

Indeed, there’s a raft of safety technology included - more on that below - and there’s also a number of Enhancement Pack options.

Luxury spec models can be equipped with a choice of two Enhancement Packs: the $2000 Enhancement Pack adds a sunroof (or moonroof in Lexus speak); or Enhancement Pack 2 (or EP2 - $5500) further adds 19-inch alloy wheels, a 17-speaker Mark Levinson sound system, cooled front seats, high-grade leather-accented interior trim, and a power-operated rear sunshade.

The IS F Sport trim line is available across the IS300 ($70,000), IS300h ($73,000) or the V6-powered IS350 ($75,000), and it adds a number of additional features over the Luxury grade.

As you can probably tell, F Sport models get a sportier look, with a body kit, 19-inch alloy wheels, standard fit adaptive suspension, sports front seats with cooling, sports pedals, and five drive modes to choose from (Eco, Normal, Sport S, Sport S+ and Custom). The F Sport grade also includes a digital instrument cluster with an 8.0-inch display, as well as leather-accented trim, and scuff plates.

Buying the F Sport grade allows customers to add further goodies by way of the Enhancement Pack for that grade, which costs $3100 and includes the sunroof, 17-speaker sound system and rear sunshade.

What’s missing? Well there’s no wireless phone charging in any grade, and no USB-C connectivity either. Note: the spare wheel is a space saver in the IS300 and IS350, but there is only a repair kit in the IS300h as there are batteries where the spare wheel would go.

There’s no go-fast IS F model sitting at the top of the tree here, nor is there a plug-in hybrid to compete against the circa-$85K BMW 330e and Mercedes C300e. But the fact the IS models all come in below $75K means it’s a pretty decent value proposition.


Alpina B58/10

The BMW Alpina B5 lists for $210,000, making it only $10K more the BMW M5 which comes with almost identical features apart from the Alpina engineering to the engine and chassis.

Arriving standard is leather upholstery, four-zone climate control, nav, the Alpina embossed-headrests, a 10.25-inch display, digital radio, Alpina door sills, sunroof, proximity key, power front seats, 12-speaker Harman Kardon stereo, head-up display, Alpina virtual instrument cluster, heated front and rear seats, and the 20-inch Alpina wheels.

The test car I drove had been optioned with a limited-slip differential ($5923), steering-wheel heating ($449); soft-close function for doors ($1150); sunblinds ($1059); TV function ($2065) ambient air package ($575), and front-seat ventilation ($1454).

Engine & trans

Lexus IS7/10

The engine specs depend on the powertrain you choose. And at a glance there’s no variance between the earlier version of the IS and the 2021 facelift.

That means the IS300 model still runs a 2.0-litre turbocharged petrol motor producing 180kW of power (at 5800rpm) and 350Nm of torque (at 1650-4400rpm). It has an eight-speed automatic transmission, and like all IS models, it is rear-wheel drive (RWD/2WD) - there is no all-wheel drive (AWD/4WD) model here.

Next up the spectrum is the IS300h model, which has a 2.5-litre four-cylinder Atkinson cycle petrol motor teamed to an electric motor and nickel metal hydride battery pack. The petrol engine is good for a 133kW (at 6000rpm) and 221Nm (at 4200-5400rpm), and the electric motor produces 105kW/300Nm - but the combined total maximum power output is 164kW, and Lexus doesn’t provide a maximum torque figure. The 300h model runs a CVT automatic transmission.

The big horsepower offering here is the IS350, which runs a 3.5-litre petrol V6 engine, producing 232kW of power (at 6600rpm) and 380Nm of torque (at 4800-4900rpm). It runs an eight-speed auto.

All models have paddle-shifters, while the two non-hybrid models have seen tweaks to the transmission software that is said to “estimate driver intentions” for better enjoyment. 


Alpina B59/10

The Alpina B5 uses the same 4.4-litre V8 engine found in the BMW M5 (and also the B7). But, and it's a big but, the M5 makes 441kW and 750Nm, while the B5 outdoes it with 447kW and 800Nm. Admittedly, the B5's torque arrives at the 3000rpm mark, while the M5's is all there from 1800rpm.

How does the B5 beat it? Alpina installed its specially developed twin turbochargers and intercoolers, a high-performance cooling system, a reconfigured air intake set up and a different exhaust system.

The B5, though, is a tenth of a second slower to 100km/h compared to the M5 with a time of 3.5 seconds, but it will blast on to a top speed of 330km/h while the M5 is limited to 250km/h in regular form and 305km/h with the optional M Driver's package.

Both uses the same ZF eight-speed automatic transmission with identical gear ratios, and both are all-wheel drive.

Fuel consumption

Lexus IS7/10

There’s still no diesel model, no plug-in hybrid and no full electric (EV) model - which means that while Lexus was at the forefront of electrification with its so-called “self-charging” hybrids, it is falling behind the times. You can get plug-in versions of the BMW 3 Series and Mercedes C-Class, and the Tesla Model 3 plays in this space in full-electric guise.

As for the fuel-sipping hero of this trio of powertrains, the IS300h is said to use 5.1 litres per 100 kilometres on the combined cycle fuel test. In reality, our test car’s dashboard showed 6.1L/100km across a mix of driving.

The IS300 with its turbocharged 2.0L engine is next best for fuel use, claiming 8.2L/100km. On our short launch drive of that model, we saw 9.6L/100km on the dashboard.

And the full-fat IS350 V6 petrol claims consumption of 9.5L/100km, while on test we saw 13.4L/100km.

The emissions for the three models are 191g/km (IS300), 217g/km (IS350) and 116g/km (IS300h). All three are Euro 6B compliant. 

Fuel tank capacity is 66 litres for all models, meaning your mileage range for the hybrid model could be considerably longer.


Alpina B57/10

The Alpina B5 needs petrol. By that, I mean it needs quite a lot of it if you want to enjoy it properly. What type of mileage does it get? Officially, it should use 11.1L/100km after a combination of urban and open roads, where as the M5 is set to 10.5L/100km.

That makes sense, the B5 produces more power and torque, and it's 85kg heavier than the M5 at 2015kg.

Our test car's trip computer was reporting 13.2L/100km after flying low over country roads and slow city piloting. The more time spent in the urban warfare that is the daily peak hour commute, the more that figure crept and hovered around the 15L/100km mark.

Driving

Lexus IS8/10

With the engine at the front and drive to the back, it has the ingredients for a pure driver’s car, and Lexus made a bit of a big deal about the new-look IS being more focused thanks to chassis adjustments and track width improvements - and it does feel a pretty nimble and tied-down car in the twisty stuff. 

It is competent at stitching together a series of corners, and the F Sport models are particularly adept. The adaptive suspension in those models includes both anti-dive and anti-squat tech, which is designed to make the car feel solid and flat on the road - and it does, thankfully without feeling twitchy or uncomfortable, with good suspension compliance even in the most aggressive Sport S+ drive mode.

The 19-inch wheels on F Sport models are fitted with Dunlop SP Sport Maxx rubber (235/40 front, 265/35 rear) and there’s plenty of tarmac tenacity.

The grip from Luxury-spec models on 18s could be better, with those Bridgestone Turanza tyres (235/45 all around) proving not quite the most enthralling. 

Indeed, the IS300h Luxury I drove felt very different in character to the F Sport IS300 and 350 models. It was surprising how much more of a plush-focused model the Luxury grade feels, and likewise it wasn’t as impressive in dynamic driving due to the tyre grip and less-enthusiastic drive mode system. The non-adaptive suspension is a touch more jittery too, and while it’s not to the point of discomfort, you might expect better for a car on 18s.  

Across all models the steering is accurate and direct enough, with predictable response and decent feel to the driver’s hands for this electric power steering setup. The F Sport models have even further retuned steering for “an even sportier drive experience”, though I found at times it could feel a little numb for rapid changes of direction. 

As for engines, the IS350 is still the pick. It has the best zest, and feels the most fitting powertrain for this model. It sounds good, too. The auto transmission is pretty clever, there's easily enough pulling power, and it's probably going to be the last of the non-turbo V6s in Lexus's line-up when this cars life-cycle is up.

The IS300's turbo engine was the most disappointing, lacking some urge and constantly feeling bogged down by turbo lag, transmission confusion, or both. It felt underdone in enthusiastic driving, though in dull day-to-day commuting circumstances it came across as more acceptable, though the remapped transmission software was far less impressive in this application than in the IS350.

The IS300h was a lovely, quiet and refined experience all around. It’s the one you should go for if you don’t really care about all that go-fast stuff. The powertrain is proven, it accelerates with nice linear delivery, and at times it’s so hushed I found myself looking down at the instrument cluster to see if the car was in EV mode or if it was using the petrol engine. 


Alpina B58/10

Ok, stay with me here. For this next bit you'll need a fresh egg, a lounge chair, and it might be a good idea to have some plastic bags and carpet cleaner on hand.

First, in front of the lounge chair flatten out the plastic bag and place the egg on it. Next, sit down on the chair and very carefully rest the ball of your foot on the egg with as little pressure as humanly possible.

This is exactly how little force you need to apply to the go-pedal of the B5 to accelerate from a standstill to 60km/h in about five seconds.

If anything sums up the driving experience of the B5, it's that sense of effortlessness.

Stomp on that accelerator, and you'll be shot to 100km/h in 3.5 seconds, without a hint of broken traction thanks to the all-wheel-drive system.

The ride should have been terrible on 20-inch wheels shod in low-profile rubber (Pirelli P Zero 255/35 front, and 295/30 rear), but the Alpina-tuned air suspension is close to miraculous in the way it cushioned and censored the potholes out of Sydney's worst roads. Yes, it can be a touch floaty, particularly in the Comfort Plus setting, but this is benchmark-setting stuff for a comfortable ride.

Don't expect this beast to roar. Unlike the M5, the B5 gets its work done without deafening everybody around it. Sure, the B5's V8 sounds amazing when you push it, but it's not brash, not loud and not lairy. Buy an M5 or Mercedes-AMG E63s if you want to be heard half a block before you get home, but you won't get that with the B5 and its exhaust system.

The B5 also handles well, but I have to say the engagement factor is low. I piloted it effortlessly through the twists and turns of my country test circuit and roads which normally have me grinning like a maniac behind the wheel had me feeling a bit disconnected in the B5. That air suspension, the numb steering and pedal actions make it difficult to ‘feel' the road.

It's highways where the B5 is a king, but even at 110km/h there's the sense that this car is still fast asleep and won't get out of bed for anything less than 150km/h - making it perfect for Germany's autobahns, but maybe not for here in Australia.

Safety

Lexus IS9/10

Safety equipment and technology has been upgraded for the IS 2021 model range, though it is expected to carry over its existing five-star ANCAP crash test rating from 2016.

The facelifted version scores auto emergency braking (AEB) with day and night pedestrian detection and daytime cyclist detection (from 10km/h to 80km/h) and car detection (10km/h to 180km/h). There’s also all speed adaptive cruise control with low speed following.

The IS also has lane keeping assistance with lane departure warning, lane trace assist, a new system called Intersection Turning Assist which will brake the car if the system judges the traffic gap isn’t big enough, and there’s also road sign recognition.

Plus the IS has blind-spot monitoring on all grades, as well as rear cross-traffic alert with auto braking (below 15km/h).

And beyond that, Lexus has added new Connected Services features, including an SOS call button, automated collision notification if an airbag deploys, and stolen vehicle tracking. 

Where is the Lexus IS built? Japan is the answer.


Alpina B59/10

The Alpina B5 is based on the BMW 5 Series which had a five-star ANCAP rating awarded to it in 2017.

Along with the comprehensive suite of airbags, traction and stability control, there's an impressive array of advanced safety equipment. Coming standard is AEB (front and rear), evasive steering, front and rear cross-traffic warning, blind-spot alert and lane-keep assist. The Alpina B5 also comes with BMW's emergency call function.

For child seats you'll find two ISOFIX mounts and three top tether points across the rear row.

If you're unfortunate enough to get a flat tyre, there's a puncture repair kit in the boot which works provided the hole isn't giant, as I've experience in the past with these systems.

Ownership

Lexus IS7/10

On paper, Lexus’s ownership offer isn’t quite as enticing as some other luxury car brands - but it has a strong reputation for blissful ownership.

The Lexus Australia warranty period is four years/100,000km, which is better for duration than Audi and BMW (both three years/unlimited km) but not as accommodating as Mercedes-Benz or Genesis, each of which offer five-year/unlimited km warranty.

The company has a three-year capped price servicing plan, with maintenance every 12 months or 15,000km. The first three visits cost $495 each. That’s okay - but Lexus doesn’t offer free servicing like Genesis, and nor does it offer prepaid service plans - for three to five years for a C-Class, and five years for Audi A4/A5, for instance.

There is complimentary roadside assistance for the first three years, too.

That said, the company has its Encore ownership benefits program that allows a number of experiences and deals, and the service team will collect your car and return it, leaving you with a loan car if you need it.

 


Alpina B57/10

The Alpina B5 is covered by BMW's three-year/unlimited kilometre warranty. Servicing is recommended every 12 months or 15,000km.
