--- version: alpha name: BMW description: BMW's corporate site — distinct from BMW M's motorsport-bombastic variant, this is a measured and settled corporate-automotive interface. On a light (cream-tinted white) canvas, BMW corporate blue (#1c69d4) carries every primary CTA; dark navy hero bands frame model photography. BMW Type Next Latin sets the entire hierarchy on two weights — heavy 700 display and Light 300 body. Configuration and reservation flows ride a card-based 4-up grid, where each card holds a model render, a name, and a "Learn More" link. colors: primary: "#1c69d4" primary-active: "#0653b6"

site carries a far more **measured, corporate-automotive** interface than its motorsport-bombastic cousin BMW M. The atmosphere is light: `{colors.canvas}` (#ffffff) is the base surface, `{colors.surface-card}` (#fafafa) carries the soft-grey card plates, and dark navy `{colors.surface-dark}` (#1a2129) appears only inside hero bands — one per page, framing the lead model render. Type runs BMW's licensed **BMW Type Next Latin** at two weights: heavy 700 (display + button + nav) and Light 300 (body + secondary copy). That contrast — heavy display next to thin paragraph — is the editorial signature, channeling the brand's "European-engineered" voice. Weight 500 is deliberately absent; weight 400 only appears on caption and nav-link in neutral utility contexts. The brand action color, **BMW corporate blue** (`{colors.primary}` — #1c69d4), works alone across every primary CTA — buttons are **rectangular, 0px corner**, with white type. The site rotates a blue-button + dark-navy-hero combination across page rhythm. The M tricolor stripe (`{colors.m-blue-light}` → `{colors.m-blue-dark}` → `{colors.m-red}`) only appears in motorsport contexts and as M-model badges/dividers — never in the corporate site's main language. The configuration and reservation flows add a dealer-side inventory UI on top of the same system — filter chips, model cards, price tables — but typography and color stay identical; only density goes up. **Key Characteristics:** - Light `{colors.canvas}` is the base surface; dark navy `{colors.surface-dark}` appears only inside hero bands — page rhythm relies on contrast. - BMW corporate blue (`{colors.primary}` — #1c69d4) acts as the single primary action color. - BMW Type Next Latin: weight 700 display against weight 300 body is the signature. - Buttons are **rectangular, 0px radius** — corporate dialect, distinct from M's sportier radii. - Model cards run as 4-up or 5-up grids with no hairline border or only minimal border — just white plate + photo + title. - Photography (model renders) sits in environment, no shadow — depth comes entirely from color-block contrast. - M tricolor stripe appears only in M-model contexts — not part of the corporate language. - Section rhythm holds at `{spacing.section}` (80px) for every major band. ## Colors ### Brand & Accent - **BMW Blue (Primary)** (`{colors.primary}` — #1c69d4): The single brand action color. All primary CTAs, "Learn More" link prefixes (blue text), nav-link active state. Press shifts to `{colors.primary-active}` (#0653b6). - **M Blue Light** (`{colors.m-blue-light}` — #0066b1) + **M Blue Dark** (`{colors.m-blue-dark}` — #1c69d4) + **M Red** (`{colors.m-red}` — #e22718): The M tricolor stripe — appears on the corporate site only on M-model pages and the "M" badge. Never as CTA colors. ### Surface - **Canvas** (`{colors.canvas}` — #ffffff): The default page surface. - **Surface Soft** (`{colors.surface-soft}` — #f7f7f7): Soft grey for the footer and sub-navigation bands. - **Surface Card** (`{colors.surface-card}` — #fafafa): The light plate behind a model card's photo block. - **Surface Strong** (`{colors.surface-strong}` — #ebebeb): A slightly heavier grey used as a section divider. - **Surface Dark** (`{colors.surface-dark}` — #1a2129): Dark navy for hero bands and large dark CTAs. Not pure black — carries a warm undertone. - **Surface Dark Elevated** (`{colors.surface-dark-elevated}` — #262e38): One step lighter, used for nested cards on top of the dark hero. ### Hairlines - **Hairline** (`{colors.hairline}` — #e6e6e6): The 1px divider — input outline, configurator card outline, table separator. - **Hairline Strong** (`{colors.hairline-strong}` — #cccccc): A more visible 1px outline — disabled secondary buttons, emphasized table border. ### Text - **Ink** (`{colors.ink}` — #262626): All display and primary text. Not pure black — soft against photography. - **Body** (`{colors.body}` — #3c3c3c): Default running text. - **Body Strong** (`{colors.body-strong}` — #1a1a1a): Emphasized paragraphs and lead text. - **Muted** (`{colors.muted}` — #6b6b6b): Footer links, breadcrumbs, captions. - **Muted Soft** (`{colors.muted-soft}` — #9a9a9a): Disabled text, fine-print legal. - **On Primary** (`{colors.on-primary}` — #ffffff): White text on a blue button. - **On Dark** (`{colors.on-dark}` — #ffffff): White text on a dark hero band. - **On Dark Soft** (`{colors.on-dark-soft}` — #bbbbbb): A slightly muted white for secondary text on dark bands. ### Semantic - **Success** (`{colors.success}` — #22c55e): Confirmation messages and "available" indicators. - **Warning** (`{colors.warning}` — #f59e0b): Warning callouts. - **Error** (`{colors.error}` — #dc2626): Validation errors. ## Typography ### Font Family The system runs **BMW Type Next Latin** in two cuts: regular (display + UI labels) and **BMW Type Next Latin Light** (body + secondary copy). Fallback stack: `system-ui, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif`. The display/body split is functional: - BMW Type Next Latin (700) → display headlines, button labels, nav links - BMW Type Next Latin Light (300) → paragraphs, descriptive copy - BMW Type Next Latin (400) → caption, neutral nav-link contexts This three-way split mirrors BMW M's — corporate and the M sub-brand share the same typographic DNA; only the weight/size ratios differ. ### Hierarchy | Token | Size | Weight | Line Height | Letter Spacing | Use | |---|---|---|---|---|---| | `{typography.display-xl}` | 64px | 700 | 1.05 | 0 | Hero h1 ("iX3", model name) | | `{typography.display-lg}` | 48px | 700 | 1.1 | 0 | Section heads | | `{typography.display-md}` | 32px | 700 | 1.15 | 0 | Sub-section heads | | `{typography.display-sm}` | 24px | 700 | 1.25 | 0 | CTA-band headlines | | `{typography.title-lg}` | 20px | 700 | 1.3 | 0 | Card group titles | | `{typography.title-md}` | 18px | 700 | 1.4 | 0 | Model card title, intro paragraphs | | `{typography.title-sm}` | 16px | 700 | 1.4 | 0 | Inventory card title, list label | | `{typography.body-md}` | 16px | 300 (Light) | 1.55 | 0 | Default body — BMW Type Next Latin Light | | `{typography.body-sm}` | 14px | 300 (Light) | 1.55 | 0 | Footer body, fine-print | | `{typography.caption}` | 12px | 400 | 1.4 | 0.5px | Photo captions, meta | | `{typography.label-uppercase}` | 13px | 700 | 1.3 | 1.5px | "LEARN MORE" inline links, category tabs | | `{typography.button}` | 14px | 700 | 1.0 | 0.5px | Standard CTA button label | | `{typography.nav-link}` | 14px | 400 | 1.4 | 0.3px | Top-nav menu items | ### Principles - The **700/300 contrast** is the editorial signature. Weight 500 is absent from the system. - **No negative letter-spacing** — BMW Type Next Latin works on a wide body, so tracking stays at default. Apple/Cal.com-style tightening reads off-brand here. - **UPPERCASE inline links** — "LEARN MORE"-style CTAs run uppercase with 1.5px tracking. The "machined precision" voice. - **Weight 400 lives in a narrow lane** — only caption and nav-link, both neutral utility roles. ### Note on Font Substitutes BMW Type Next Latin is a licensed BMW typeface. Open-source alternatives: - **Inter** (variable) — close match at weight 700/300. Leave letter-spacing at 0.0em. - **Saira Condensed** — for a slightly more compressed BMW Type feel. ## Layout ### Spacing System - **Base unit:** 8px. - **Tokens:** `{spacing.xxs}` 4px · `{spacing.xs}` 8px · `{spacing.sm}` 12px · `{spacing.md}` 16px · `{spacing.lg}` 24px · `{spacing.xl}` 32px · `{spacing.xxl}` 48px · `{spacing.section}` 80px. - **Section padding:** `{spacing.section}` (80px) for every major editorial band. - **Card internal padding:** `{spacing.lg}` (24px) for model and feature cards. ### Grid & Container - **Max content width:** ~1440px center-aligned. - **Editorial body:** A single 12-column grid. - **Model card grids:** 4-up or 5-up at desktop, 2-up at tablet, 1-up on mobile. - **Configurator inventory grids:** 3-up filter row + 4-up vehicle cards, dense layout. ### Whitespace Philosophy BMW's whitespace strategy is tighter than BMW M's motorsport-aerated grenadier — the corporate side is more utility-driven. Section rhythm is 80px (not M's 96px). Card padding is 24px (not M's 32px). The page is denser, more dealership-functional. ## Elevation & Depth | Level | Treatment | Use | |---|---|---| | Flat | No shadow, no border | Body, top nav, footer, hero bands | | Soft hairline | 1px `{colors.hairline}` border | Configurator option tile, table divider | | Card surface | `{colors.surface-card}` background — no shadow | Model card photo plate | | Photographic | Edge-to-edge photography | Hero band, model renders | The system never uses a drop shadow. Depth comes entirely from (a) color-block contrast (light canvas vs dark hero) and (b) photographic subject + lighting. ### Decorative Depth - **`m-stripe-divider`** — a 4px-tall horizontal tricolor stripe (`{colors.m-blue-light}` → `{colors.m-blue-dark}` → `{colors.m-red}`). Only in M-model contexts, motorsport badges, or as an M-related section divider. Not part of the main corporate flow. - **Photographic depth** — full-bleed vehicle photography (lighting + subject) does the work chrome would otherwise do. ## Shapes ### Border Radius Scale | Token | Value | Use | |---|---|---| | `{rounded.none}` | 0px | Every button, card, input, configurator chip — the dominant radius | | `{rounded.xs}` | 2px | Very small badges, very rare | | `{rounded.sm}` | 4px | Small inline button (rare) | | `{rounded.md}` | 8px | Mobile-only collapse cards (rare) | | `{rounded.lg}` | 12px | Very rare — modal/dialog corners | | `{rounded.pill}` | 9999px | Filter chips in some contexts (rare) | | `{rounded.full}` | 9999px / 50% | Avatar, circular icon button | The radius hierarchy is binary: **rectangular for everything, circular only for icon buttons.** A clear departure from the soft-cornered SaaS dialect of Apple or Cal.com — closer to BMW corporate-automotive's "engineered precision" voice. ### Photography Geometry - Hero photography is full-bleed at 16:9 or 21:9 cinematic ratio. - Model card photos sit at 16:10, edge-to-edge with `{rounded.none}` corners. - Configurator vehicle renders sit on a white studio background, full silhouette visible. ## Components ### Top Navigation **`top-nav`** — A white sticky nav bar pinned to the top of the page. 64px tall, `{colors.canvas}` background. Left: BMW circular badge logo; center: primary horizontal menu (Models, Next Generation, Pre-Owned, Dealers, Test Drive); right: cart icon, language picker, profile. Menu items render in `{typography.nav-link}` (14px / 400 / 0.3px tracking). ### Buttons **`button-primary`** — The signature primary CTA. Background `{colors.primary}` (BMW Blue #1c69d4), text `{colors.on-primary}`, type `{typography.button}` (BMW Type Next Latin 14px / 700 / 0.5px tracking), padding 14px × 32px, height 48px, rounded `{rounded.none}` (0px — rectangular). Press state: `button-primary-active` shifts to `{colors.primary-active}`. **`button-secondary`** — A white button with a hairline outline. Background `{colors.canvas}`, text `{colors.ink}`, 1px `{colors.hairline-strong}` border, same padding + height + radius. **`button-secondary-on-dark`** — Used over a dark hero band. Background transparent, text `{colors.on-dark}`, 1px `{colors.on-dark}` border, same rectangular shape. **`button-text-link`** — An inline UPPERCASE letter-spaced link. No background, text `{colors.ink}`, type `{typography.label-uppercase}` (13px / 700 / 1.5px tracking). Reads as "LEARN MORE", terminated by a `›` chevron. **`text-link`** — An inline link inside body copy. `{colors.ink}` text, no underline by default; underlines per context. ### Cards & Containers **`hero-band-dark`** — Full-width dark navy hero. Background `{colors.surface-dark}`, text `{colors.on-dark}`, vertical padding `{spacing.section}` (80px). Centered: model name in `{typography.display-xl}` (64px / 700) + sub-headline + vehicle render (right-aligned or below). A single `{component.button-primary}` (blue) or `{component.button-secondary-on-dark}`. **`hero-photo-band`** — A light-canvas model showcase band. Background `{colors.canvas}`, text `{colors.ink}`. The vehicle render takes the wide area; right or below, a headline + two link CTAs + sub-tagline. **`model-card`** — Used in 4-up or 5-up model card grids on the homepage ("BMW iX3", "BMW iX", "BMW 5 Series"). Background `{colors.canvas}`, rounded `{rounded.none}`, padding `{spacing.lg}` (24px). Contents: model render at the top (`{component.model-card-photo}` on `{colors.surface-card}`), model name in `{typography.title-md}` (18px / 700) below, a one-line tagline in `{typography.body-sm}` (14px / 300), and a `{component.button-text-link}` ("LEARN MORE ›"). **`model-card-photo`** — The card's photo plate. Background `{colors.surface-card}` (#fafafa — soft grey), rounded `{rounded.none}`, vehicle render in full silhouette. Zero padding — the photo runs edge-to-edge. **`feature-photo-card`** — A feature/lifestyle card. Background `{colors.canvas}`, padding `{spacing.lg}`. 16:9 photo at the top, `{typography.title-md}` headline + body excerpt below. **`spec-cell`** — A technical spec cell (model detail page). Transparent background, separated by hairline dividers. Value on top (`{typography.display-sm}` 24px / 700), label below (`{typography.label-uppercase}`). ### Inventory & Configurator **`inventory-card`** — One card per vehicle on the dealer inventory page. Background `{colors.canvas}`, padding `{spacing.md}` (16px), rounded `{rounded.none}`. Vehicle photo on top, model + variant name + price + "View" link below. **`filter-chip`** + **`filter-chip-active`** — Inventory filter chips (model, year, price range). Inactive: background `{colors.canvas}`, 1px `{colors.hairline-strong}` border, text `{colors.ink}`, type `{typography.caption}`. Active: background `{colors.ink}`, text `{colors.on-dark}`. Padding 8px × 14px, radius `{rounded.none}`. **`configurator-option-tile`** + **`configurator-option-tile-selected`** — Configurator selection cell (color, wheels, upholstery). Inactive: background `{colors.canvas}`, 1px hairline. Selected: 2px `{colors.primary}` border. Padding 16px × 24px, radius `{rounded.none}`. ### Inputs & Forms **`text-input`** — Standard text input. Background `{colors.canvas}`, text `{colors.ink}`, type `{typography.body-md}`, rounded `{rounded.none}` (0px), padding 14px × 16px, height 48px, 1px hairline border. On focus, the border thickens to ink. **`cookie-consent-card`** — Cookie banner. Background `{colors.canvas}`, 1px hairline, padding `{spacing.lg}` (24px), `{typography.body-sm}` (14px / 300 — Light even in legal copy). ### Tabs / Tags **`category-tab`** + **`category-tab-active`** — Category sub-nav. Inactive: transparent + `{colors.muted}` UPPERCASE label. Active: transparent + `{colors.ink}` UPPERCASE label + 2px ink underline. 12px vertical padding, no horizontal radius. ### Brand Signature **`m-stripe-divider`** — A 4px-tall horizontal tricolor stripe (`{colors.m-blue-light}` → `{colors.m-blue-dark}` → `{colors.m-red}`). Only in M-model contexts, motorsport badges, or as an M-related section divider. Absent from the corporate main flow; on M-model detail pages and the M Performance badge it plays an inline divider role. ### CTA / Footer **`cta-band-photo`** — A pre-footer "Discover the New iX3"-style band. Background `{colors.surface-dark}` with a full-bleed vehicle photo. Centered headline in `{typography.display-md}` (32px / 700) + a single `{component.button-secondary-on-dark}`. 80px padding. **`footer`** — The closing soft-grey footer. Background `{colors.surface-soft}` (#f7f7f7 — not pure white — soft grey), text `{colors.body}`. A 4-column link list: Models / Services / Dealers / About. Vertical padding 64px. Below, a copyright line in `{typography.body-sm}` with `{colors.muted}`. ## Do's and Don'ts ### Do - Sit every page on `{colors.canvas}` (pure white); reserve `{colors.surface-dark}` for hero bands only. - Pair primary CTAs with `{colors.primary}` (BMW Blue) + `{colors.on-primary}` white text + `{rounded.none}` 0px corners — the corporate signature. - Set display headlines in BMW Type Next Latin 700 and body in Light 300. The contrast is non-negotiable. - Use UPPERCASE letter-spaced links like "LEARN MORE" as inline CTAs. - Place the model card photo on `{colors.surface-card}` with the title beneath — the standard BMW corporate pattern. - Hold section rhythm at `{spacing.section}` (80px) — tighter than BMW M's 96px. - Reserve the M tricolor stripe for M-model contexts and motorsport dividers. ### Don't - Don't add a brand color other than blue — BMW Blue is the only primary action color. - Don't use pill or rounded buttons — `{rounded.none}` (0px) rectangular IS the brand button. - Don't drop display weight to 500 — the system uses 700 / 400 / 300; 500 is absent. - Don't bold body type — Light 300 is the BMW corporate editorial voice. - Don't add drop shadows to cards — depth comes from photo + color-block contrast. - Don't repeat the same surface mode across two consecutive bands — light → dark hero → light → light feature → dark CTA → light footer rotation is required. - Don't use the M tricolor stripe as a CTA fill — divider/accent role only. - Don't mix languages in a single page — UI language must stay consistent. ## Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |---|---|---| | Mobile | < 768px | Hamburger nav; hero h1 64→40px; model card grid 1-up; configurator filter chips 2-up; footer 4 col → 1 col | | Tablet | 768–1024px | Top nav narrows, secondary menu hides under "More"; model card 2-up; inventory 2-up | | Desktop | 1024–1440px | Full top-nav; 4-up or 5-up model card grid; inventory 3-up; full configurator UI | | Wide | > 1440px | Same as desktop, content fixed at 1440px; gutters absorb the rest | ### Touch Targets - `{component.button-primary}` minimum 48 × 48px — above WCAG AAA (44 × 44). - `{component.text-input}` height 48px. - Category tabs run with 12px vertical padding, giving an effective tap area > 44px. ### Collapsing Strategy - The top nav collapses to a hamburger below 768px; the menu opens as a full-screen sheet. - The hero band's internal layout drops to a single column. - Model card grid 4-up/5-up → 2-up → 1-up. - The configurator filter chip row scrolls horizontally on mobile. - The M tricolor stripe stays at 4px height across every breakpoint. ### Image Behavior - Model renders scale at every breakpoint while preserving native aspect ratios. - Hero photography may shift to a more vertical crop on mobile (art direction). - Inventory vehicle photos may move from 16:9 to 4:3 on mobile. ## Iteration Guide 1. Focus on a single component. Reference its YAML key directly (`{component.model-card}`, `{component.button-primary}`). 2. New components default to `{rounded.none}` (0px). Use `{rounded.full}` only for circular icon buttons. 3. Variants (`-active`, `-disabled`, `-selected`) live as separate entries inside the `components:` block. 4. `{token.refs}` everywhere — never inline hex. 5. Hover state is never documented. Only Default and Active/Pressed states. 6. Display headlines stay BMW Type Next Latin 700; body stays Light 300; the trio is fixed. 7. Keep UI strings in a single language — match the locale of the page. ## Known Gaps - BMW Type Next Latin is licensed to BMW and not published as a public web font; Inter at weights 700/300 is documented as the substitute. - Animation and transition timings (configurator color swap, model card hover-reveal) are out of scope here. - Form validation states beyond `{component.text-input}` focus were not extracted — error/success states would need a dedicated form page. - The dealer inventory sub-domain shares typography and color with the main corporate site; only UI density rises (filters, tables, prices). - A cookie consent overlay can occlude part of the hero — the lead hero band content may not be fully captured. - The M tricolor stripe appears infrequently on this corporate site; full motorsport context lives on the BMW M site.
